Reverb Comment comment

From: http://bbs.gxhc365.com/thread-346375-1-1.html

[Liupin] This is related to a music enthusiast.ArticleBy reading this topic, we can have a comprehensive understanding of reverb and study reverb.AlgorithmIt still has a certain guiding role. This topic is in traditional Chinese characters and cannot be read.

I have read the topic that I have been using so far. The effect is only a string of knowledge, delay,
Flanger (which includes chorus) and some articles have been written to compresser, which is the most common
The effect reverb should also be used.

(As a result, I found that I had to upload an extremely large article to complete this article. After I finished it, I was very impressed! How can this problem be solved? )

Starting with this topic, you must take a breath! Think of a wonderful age where early equipment was simple,
What are the advantages of this topic? It's not just a speaker, or a reverb on a karaoke companion speaker.
Or echo success. Just make it small!

Then the equipment will become more and more professional, and the rack Effect of zookeeper will be used. It's so strange!
How can there be so many things with a reverb effect? Then, enter digital again,
The power generation, the digital effect, some audios, and plug-in. Wow! Reverb
How can there be so many parameter numbers! You can't understand all of these products!
Even if we understand their meaning, how can we use it?

At that time, I went to ask some old people who were playing audio games (there was no Internet to find information ).
What is the meaning of linear regression? How to use it! As a result, ODPS was unfortunate to have met
It's a bunch of old people who don't want to solve the problem. They actually replied that reverb is not just a sense of space!
Just try again and try again to get the space you need. Remember that it will be good to use it next time!

[Liupin] reverb is the special effect of various virtual spaces.

(1) What are the differences between the basic concepts of reverb effect and delay?

I started to explain today's reverb problem! Audio equipment is already in such high technology,
I think we can no longer try it out, so we should study it well (not just liquor ),
In particular, so many netizens have digital devices, diagnostic tools, and efficient devices, and a bunch of words inside them,
I don't know the data. As a result, it turns into something else. I believe many people are doing this.

I will use the most white-spoken text (or White-Eye text) to solve the problem, so that various levels of netizens can
After reading this article, you will understand it all!

Let's take a look at the formation of a reverb space. We all know that in a big room, a big hall, a cathedral,
Or what kind of feeling is the voice and space produced by different environments when I listen to the concert at the training venue?
There must be a concept in this article.

First, let's analyze all the components that form such a blank effect. What are the things that make reverb,
Echo, what about delay?

Let's assume that you are on the four walls of a house. Nothing is empty. Cement and high-rise buildings, one
It's good to be in a huge empty room. I sing here and you are listening. This kind of environment will certainly feel free to analyze.
Here are some things you can hear:

1. When I sing to you, the original sound of your ears is straight from my mouth, that is, the original music of your ears.
Direct Sound

2. audio streams are directed to the walls, houses, floors, and so on in all directions. They are re-reflected and combined.
When it comes to your ears, the original speaker is early reflection, Echo
In fact, this is the case. However, this case is more accurate than direct to your original direct
Sound must appear slowly, and the sound quality is usually not the same as that of the original sound.
Empty space, because of the impact on the ceiling, there are still windows, such as low windows, equipment, etc., the energy is absorbed
After reflection, the tone is often blurred, blurred, or even buzzing.

What kind of tone does early reflection sound like this slow one to your ears? Is very close
Original tone? Or is it blurred? It is quite different from the original sound.
Buzzing? What is the cause of this situation! Big Data room, big pub, big data Hall
In the education field, are there furniture and other oriental shadows in these places? Early
Different reflection sounds

[Liupin] the reply should be under 30 ms. Otherwise, the voice may be ambiguous.

3. The next step is the regression of the regression, which is decay, that is, early above.
The reflection sound will not be like the direct sound that I originally sang. I can instantly change my mouth
Without sound, it will naturally become smaller and smaller, and it will become less time-consuming,
Is the decay time of the reverb numeric (some devices use the word decay or time ),
It is calculated using a law called rt60. Simply put, it is a scientist studying reverb.
After studying natural audios, it is found that the audios in this region are all lost when the audios are reduced by 60 dB.
Therefore, the decay time is the time it takes for early reflection to drop 60 dB.
Long and Short

4. There are early reflection and late reflection. Simply put, this is the voice.
It will hit other ideas and reflection again, but it will hit your ears again! In many natural sounds
Normally, this late reflection is unknown or does not exist at all. If there is, there are many
It is not necessarily practical, so it is usually a reverb equipment or
This late reflection will be available for you to set

 

The above are the most basic elements that make the reverb space sense.
The most simple principle of reverb creation is-the method to use the original audio to create an image like early
The reflection of the reflection tone will naturally decay, and then a little longer
Mixing in the original sound has a reverb effect.

I just need to refresh the reed reverb on the guitar speaker as an example. It works by taking the guitar
There was a mirror on the other end of the mirror, and there was something like a picker or a hacker.
Receive, the person who found the spring reverb found the energy absorption and vibration of the spring,
The sound received by the other end is a kind of early reflection tone, and then it is slightly
The original guitar sound is mixed into Yan. do you understand this?

 

Again, the reverb is different from delay. One of the earliest mechanical rebs is tape.
Reverb, that is, after the original sound is downloaded using the audio band, it is played at an extended playback point and mixed into the original sound,
It's time to feel free, but it's time! The voice in this region is of course the same as the original sound.
Early reflection, natural decay and so on are mostly not the same, this tape reverb
Sometimes, the device has to handle the tone with a deliberate attempt to make it look like a natural echo,
In addition, I want to make a natural sense of decay.

Digital delay is widely used to know that, when it is used for reflection, it should be called a delayed audio
The original sound is completely the same as the perfect reflection, which is unlikely to have such a perfect reflection in the natural environment.

The second point is that the delay effect is not in charge of the decay time, but is the length of the original sound.
The sound is as long as it is. The delay effect must be replaced with a smaller value because it appears.
I cannot hear it. The time length of the delayed audio and the ratio of the original audio volume are different.
My delay questions

The third point is that delay's delayed voice can be generated only when it is very slow, and the ears can clearly differentiate, for example
It can be two or three seconds. Generally, the early reflection time difference may be extended in the room,
It may be as short as the ears can not be distinguished, just like the previous, early reflection is a lot
The reflected voice is not a single voice, and it is not necessarily a standard voice like delay.
Effector ~ Ah ~ Ah ~ Ah ~ Ah ~ This is a perfect overlap.

Now that everyone understands reverb, why is the delay effect different? Delay is not natural,
Just like chorus, it is the effect set by the engineering engineer, which is similar to reverb.
In principle, delay is like an imaginary perfect music environment, and it is always super hard to be perfect.
When you yell at the wall of the reflection wave, it will only generate a single reflection audio when it is not in place.
The sound is similar to your original sound, and it will take a fixed period of time for the second place,
In the third sector, even when I was not able to hear it, it was unlikely that the natural music environment would generate such a situation.
DELAY EFFECT

[Liupin] the implementation of a simple reverb algorithm is to use a filter to make different Delays for Different frequency components and then add a mixture.

A simple structure of the Schroeder mixer:

 

Naturally, the reverb may also have some delay audio back for several times, so our Effect Generator
You can also use reverb and delay to create this sensation.

Therefore, delay and reverb work in a similar way, they are all results that can create a sense of space, so
In terms of classification, these two are empty series efficient devices. However, for example, if the delay scheme is not good
Without a sense of emptiness, it changes to imaging a person's stuttering speech, so what is the case when reverb is used together? What
What is the case when combined with delay? What are the mixed scenarios for use? When should I use it? This article
Further explanation

 

(2) parameters of the reverb

 

Now, we are beginning to adjust the reverb numbers, and I will also introduce some ways to set their knowledge and application.

Reverb usually see the number of images, or there are probably some such images, and all the equipment or software in the memory will have
More, there may be only one of them:

Early reflection:
The data volume on different devices or devices is not the same, and there is a possibility (or it is fixed at all)
Type, no data for Coco charts). For example, room size is a common metric.
The temperature of the device is not the same as that of the device.
We will give you some audio venues and domain names for you to choose, such as small room, large room,
Large Hall, arena, large club, and spring reverb
Spring), plate reverb (gold plate, what is this thing in the future), tape
Reverb and other equipment, each of which has its own characteristics, such as Hall.
Of course, the space is larger than the room. What kind of space is used? Some application will be implemented later

Some devices also have early reflection level that can be used in the early stages, as well
As mentioned above, some of them have reached the late reflection (which will include some of the following metric data) so that you can
In addition, the homophone rereflects the secondary part.

 

Decay time:
Some devices use the word "Decay" or "time", which means that the device has been replaced
Early reflection has a short length, and the rt60 law mentioned earlier has less than 60 dB.
The required time, so if you want to hear a natural voice, you need to select early reflection
To work with the optimization, you can choose a large space, and the waiting time will take a long time. However, if you set it very short, you can hear it.
It is not natural, but it may also be a good setting for a timer. There is no law for the play effect.
In the end, I heard it very well. That's right. If you don't hear it, it's just a warning.

Some devices or software have high frequency and low frequency decay time.
It can be set to different lengths and lengths of high and low voices, for example, female tweeting, or learning the color wolf.
When the high-pitched crying component grows the decay time in the high-pitched part, the high-pitched speaker will remain angry,
There is also a sense of shock when I learn the tiger's low-performance hacker, increasing the decay time of the low-pitched hacker
More

 

Pre-Delay Time:
It is also a unit of milliseconds (milli-second). This is when the original sound is set to your ears,
Sometimes there is a lot of space in the future. Early reflection's voice may only arrive after a while, ears
It is clear that when the time difference is reached, setting the time to be longer will make the reverb seem a bit similar.
Delay effect, because a voice is slower, but the reverb and delay are still
Different, early reflection is usually the original voice that is lost, and it will not always be clear.
The voice of the delay effect device must be replayed for a long time.
Once or twice, and too small

There is also a common application to extend this pre-delay: for example, we have a very strong financial base,
A strong attack sense is required. If the reverb is set to NULL for a moment, the audio will be sent
When attention is removed, the robustness and attack sense are lost. This pre-delay is set to a long time, with the original sound
The voice is separated from each other, so the voice will not be sent to other places at once, and the robustness will be saved.
This is also my topic about delay. Many gold-heavy gamers only use delay for short-selling,
One of the main reasons why reverb is not used at all, many netizens do not mean to look at Joe satriani
He performed with Steve Vai and found that they only used one pair of delay short connections.

 

Damping:
This is to say that if the big room is both magnetic and empty, there will be no such thing.
None of them, the sound produced by the hacker will be more difficult than the hacker. If there are furniture windows or furniture
Hard Wood, then the strong voice may be less, that is, warm up, set this
It depends on your needs. For example, I may want to make a strong music, sing a love song, and write a classical song.
Guitar, etc. I may need to Damping more soft beats.

 

High/low frequency filter or attenuation:
This is the EQ of the original early reflection audio, which removes some regions of the high and low levels.
The number of audios that can be listened to is approximately 20 ~ 20 k Hertz, the guitar's central voice is about Hz,
However, the early reflection should sound within the room, or a reverb such as a spring or plate type,
Generally, many of the high and low audios are lost, so you need to listen naturally, that is possible.
100 ~ Low latency of less than Hz, and 4 ~ Filters out all the highly efficient values above 5 k, and for example, the low
Drum, you can remove the low voice of audio so that it will not be added, because it may confuse the bass,
The hit rate is better than the hit rate.

Some reverb devices or software only have one tone, which can be used, but may only
Tweeting

 

Diffusion:
This is because the early reflection mentioned by us has been widely used or scattered in all directions, for example
The room is in the right shape. when you stand in the middle of the room and yell, early will reply to the four sides.
The reflection should be the same as the record size and the response time, which is the same as the response time.
Diffusion
Early reflection will have a large number of small rows, and some will be slower than others, so diffusion will be scattered.
Very strong, the diffusion of the average voice will make the voice sound thicker than the average voice, but sometimes the audio will be convex,
Some original sounds have become a bit confusing, so I may not like singing sounds.
When the original sound is voiced, it splits the diffusion into a bit, but note that the diffusion is too scattered.
It seems that it is not good to break into a song, so pay attention to the problem.

 

Density:
The density of audio. This is when early reflection is used, it may be used again to make a difference.
Some of the reflection components that you can hear are density-intensive and empty.
It sounds clear, or the density of mixed communication is low, and the sense of space is weakened.

The application concepts of damping, diffusion, and density are very similar in practice. You need to be sensitive.
The audio is still unencrypted. For example, I set the decay time to a long time, but I don't want the audio to be too convex.
When audio is written to the original sound, I will set the density to a lower level.

 

Direct level:
This is too easy to understand. Of course, it is the size or percentage of the original sound directly written to your ears,
This article also needs to be taken into consideration. For example, when you listen to a concert at the egg, you can only
In the back seat, the speaker on the stage was million again, but after such a long distance
It may not be easy to listen to your direct sound. You can hear the voice coming from all directions.
There is a large proportion, but it turns out that you have been playing a guitar in a very strong music hall, and your ears have a speaker.
It's only two or three feet long and you are on a huge scale again. Then, you didn't even hear the sound of this huge volume,
Almost all of them were dropped by the ultra-large direct sound generator. If you put the speaker 10 meters away, it changes again.
The ratio of the two is different, so the guitar like the one in the previous section must be strong, and the direct
Sound must be large or crisp, 100%

 

(3) Different Types of reverb explanation

[Liupin] There are many reverb types, and there are many Dolby audio technology laptops. It sounds like that.

 

As previously mentioned in early reflection regression, reverb devices or datasets often have many types
You choose, this section mainly refers to some types that you don't understand or are not familiar with, or you know,
But some features are worth mentioning: Room, Hall, church, Cathedral, large club, arena
There is no need to solve these field-based selections? What are the audios in everyone's workshop?
In this sense, I would like to mention some other things and their usage directions:

Spring reverb
As mentioned above, it is a kind of data received at the other end, which is similar to early.
The reflection sound is then mixed with the original sound to create a space effect. This is because it
Some features need to be further explained. You may find that when you have used the reverb in the reed room on the guitar
The dynamic Spring in it will generate a burst of music due to the earthquake, and now the digital
Many efficient devices also have the modular feature. Some of my equipment is too busy to work properly.
Then

That is, spring reverb has a sense of vibration, and many people have described it as Telecaster.
Sound, there is a strong smell, so it may sound quite appealing to some devices such as guitar and organ,
It is sometimes not suitable for singing in the upper-right corner, or many other hosts such as the violin.
It will also make the overall tone quite mixed. You have been connected to a guitar speaker and sang with its own voice spring.
What Is A reverb when you hear it?

Plate reverb, or some equipment is called metal reverb
That is, because spring reverb has poor performance in many usage scenarios, and even has been sealed.
The spring room is filled with oil to reduce the vibration of the spring. The result is still not good, and the project is similar
The principle of using a large gold plate instead of a spring, using a transducer in the center
However, when the sound is received at the audio pickup center on the audio board, it is found that the sound has passed through the gold board.
Early reflection is more common than spring reverb. It can also be written on the board.
Less decay time for audio-absorbing cotton, or change the receiver location to receive early reflection for different sounds

In the 670 s, tape reverb appeared previously, which was the most common reverb in the audio room,
The lead singer or all kinds of drivers are very easy to use. Today, few people may have read this big stuff.
Super busy location. You can use this screen as your guest. I searched for it and found a plate sonic.
The company is still building the website. The following is the website:

This plate or metal reverb, in fact, is not very similar to the big room, the nature of the big hall
Reverb, which is similar to spring reverb, which has its unique characteristics.
Listening results, so many current digital reverb have this option

Tape reverb
As mentioned above, we will not repeat the solution again, but like spring and plate, it produces
The reverb effect is similar to the natural voice of the big hall in the real big room.
A mechanical reverb sense, and some devices or software can be used to change the imaging delay effect device,
However, it certainly does not have the flavor of spring or plate.

 

Ambience or fight ambiance
Many people are not familiar with this issue on the international forum, because many reverb devices have such problems.
Choice. Literally, isn't it just an environment atmosphere? No! Is it

For example, if you attempt to call your girlfriend at your office, you may have a chat,
But your girlfriend still heard it and asked if you are right in the queue? You are outdoors, in-room,
She can't tell the difference.

We use ke's voice. The voice we receive also includes the voice produced by your background atmosphere,
This ambience is just about this, and it's about time. If you have a chance
Go to that kind of audio-Absorbing Material and talk in the complete audio-absorbing room of the Audio-absorbing equipment.
There is no ambience tone at all. You will find that your friend's voice changes, and you are
You may not be able to wait for a long time, and your ears will feel overwhelmed, because you don't have to worry about ambience.
When the feeling is zero, the ears are too large.

 

Gate reverb
I still remember the previous example's solution, called decay time, mentioned the rt60 law! This gate reverb
It will not wait until it reaches 60 dB, for example, when it is half 30 dB, the decay will suddenly fail,
This makes a strange reverb effect, and sometimes it may have a sense of dryness.

But this gate reverb still has its purpose. For example, when I play a drum, I don't want to play a sound,
The decay of the previous sound reverb is not complete yet. When the next sound is mixed, the dryness is lost.
If every next sound changes before the gate switches off decay, the entire system can reach the last
A sound is like this, because it is so fast,
There may have been more than a dozen audios. the decay of the first voice is not complete yet! Some equipment will give you
The other dynamic data gate appears soon.

 

Reverse reverb
This is to reverse the decay, and it does not mean that there is no warning.
The larger the latency, the longer the decay time settings will disappear. This is also a strange reverb,
Actually, I haven't applied it yet.

 

(4) Application

 

In fact, there is no rigid law when it comes to application. As I often say, there is no right or wrong effect on the server,
The final product sounds right to you. Here, we only want to give you the direction of thinking.

In fact, we have already mentioned a lot of application instructions. I believe you will not
Spring reverb is selected for the main singing contest? The reverb should be used to separate it into simple ones.
Category 3: Root qu, root Qu, and root Qu

 

Root cause:
For example, if the caster is playing a surf guitar, the speaker will know
Spring reverb exclusive, and many songs are still intentionally used by the hacker. You use other
The appearance of the fender may be a little blurred, and the early fender did not have that effect.
Dick Dale asked Leo fender to increase the lawn spring room to become today's well-known fender spring
Reverb Effect

You want to publish pop. A lot of songs are very popular, maybe reverb + delay is very popular.
If you are an old-fashioned jazz, you may not have a delay,
The reverb may be very heavy to hear the feeling of the vast wilderness. You may also feel the nu-metal.
There is almost no reverb, and delay is the most intense. You are always eager, for example, the decay mentioned above is too long,
Decay, which has many voices, has not been completed yet.

There is also the article about delay, which is also mentioned in the previous article. It is only used to play many heavy-duty guitar games.
Delay does not need reverb. In this case, we want to keep in your face and hit your attention, but I also
If you want to feel the effect for a while, you can try again in my workshop, as shown in
The reverb will easily send the voice to the speaker in a short time.
I lost the feeling of in your face, and the previous response made the reverb pre-delay pretty long.
The method of saving the token to keep the brute force, but it is still different from the sense of hearing made by delay.

 

Root scanner:
Many audios, like Bass, do not have any space effect at all. When it is added, it loses its heavy and thick sense of reality,
It will become unknown, and as mentioned above, many plug-ins do not use spring reverb, especially
Acoustic (co-native guitar), it's great to stick to the guitar. What kind of reverb is it?
They are all used together, so let's get it done!

There are also drumming or drumming machines, many of which are divided into seven or eight cores, and each component has one core,
For example, I don't want to refresh a drum to maintain a strong or a heavy upstreaming sensation.
To have a deep sense of attention, add Hall reverb and hi-hat as long as there is room reverb,
Cymbal should also be deep-seated. Tom has some similarities, but also has the most important ones.
Too late Early reflection or delay, it will become more than just a bit

 

Root effect what you want
For example, if someone wants to add a fake album live effect to a song, it is better to make a picture,
Each of them adds a different reverb near each other and re-mixes it. Then there will be an audience close to each other.
In the sense that you want to refresh the wine, you may use room, small club, and then direct
Sound should be a little late. If you want to be a ghost called a hacker, the longer the decay time should be, the better.
Five sons cry tomb, then choose the reverb like karaoke

 

I really don't want to say it's so fast. Many people playing the browser are very happy with karaoke.
The reverb on the machine is good or vulgar! In addition, it is a combination of heavy reverb and delay,
Will the original voice be heavily rendered, sometimes not like the original voice of this person?

You don't know this. At that time, when the pioneer product design team and engineering design team designed it, there were
As I thought, the largest group of karaoke machines should be those who are not doing singing and masturbate,
Finally, this reverb is used to block (or even beautify) the fans of the song king,
It will also lead to singers who have the feeling of being empty for listening and singing on the big stage.
It will be more self-built. This is why the hacker will sing, the hacker will not be able to hold it, and the last fight will continue.
Why is the JC bureau! You must have taken the reverb of karaoke as a rough record! That
I think it is a huge reverb, and it should even be a famous word.
--Karaoke reverb for me to choose
