Popular Science: gapless playback (seamless playback): -- The advantage is that you can watch continuous audio and video to achieve seamless connection, let you feel the transition from yarn to slice a to slice B.

Gapless sound
The gap-less sound is a digital audio/video format that allows seamless sound recording. It allows live music or coherent tracks to hear exactly when they are mastered and there is no blank between tracks.
Why is blank?
Most lossy audio compression methods are planned to be involved in a time/frequency domain transformation. In this way, the transformation cannot cope with any amount of data, and the change is performed once in the data block. To ensure that audio and video signals are input to all of them, a small amount of Shen Mo is added to the front and added to the input before the conversion. If a considerable amount of Shen Mo is not occupied, the entertainment time of audio and video data cannot be equal before and after compression. In these cases, Shen Mo will be decoded along with audio and video data, and the introduction will cause gaps between tracks.
Most audio and video playing software will disable the time when the audio output River will be switched to track, introduce the blank or make the existing blank bigger. Unless the starting point of the next track is immediately buffered and is introduced when the current track ends, a blank space will occur.
A compression method may be difficult, for example, because the MP3 standard does not define the method to record a considerable number of padding for the latest removal. Even if the two tracks are extracted and merged into a unique track, the blank space remains between them. This issue has recently been designed to address audio and video formats, and will lead to the correct playing of gapless audio and video.
Best Solution
It is possible to store metadata in audio and video clearly claim the entertainment time, and/or a considerable number of padding/delays are introduced in the internal code process. This information may be guaranteed, and entertainment time will remain the constant silence that has not been added after decoding. Audio and video playing software must recognize metadata and organize decoded audio and video.
The software may then need to care about keeping the output stream open between tracks. It must also buffer it similar to buffering the starting point of the current track during normal sound releasing.
If the compression method supports playing in the gap-less mode, the software properly decodes audio and video data and metadata, the next track is buffered and ready to play, and the output stream remains open between tracks, the preferred gapless audio and video are available. A collection of consistent tracks will then play like they are mastered, allowing the listener to hear their album pages as intended by the author.
Available solutions
(DSP) plugins may be used to detect the sound of Shen Mo between tracks and organize audio and video when necessary. This is not the best solution because it does not always lead to the same results and sources. Sometimes the artist may intentionally leave the role of Shen Mo in the orbital boundary as intense; cancel this and cancel that role.
It may and is difficult to implement Shen Mo removal as appropriate. If the Shen Mo threshold is too low and the track contains decoder manual products, the software cannot recognize some Shen Mo. Conversely, if the threshold is too high, the software may remove the whole part of the quiet music at the beginning or end of the track.
DSP plugins may be used between tracks. This eliminates scattered gaps found by some listeners, and greatly modifies audio and video data and is not desirable. In particular, when the track is considered to be playing and performing together at a large capacity, the cross fades and causes a large capacity to fall.
These two solutions are typically used. The speech does not support the method for compressing the sound of metadata for the gap less. Like the best solution, they still require intermediate conversions and do not close the output stream; however, they require more computing to make them less efficient. In portable digital audio and video players, this may mean reduced playing time in battery.
Due to the disadvantages of the alternative solution above, some of the listeners they try to remove are annoying and their negative effects are more blank.
Other options will ignore the orbital boundary. A unique collection of input tracks serves as a unique compressed file, relying on implied sheets (or similar things) for sailing. When this method causes the collection of gapless sound within the orbit, it may be bulky due to the possibility that the resulting compressed file may be large or small. In addition, unless the sound-releasing software or hardware may recognize the implied sheet, driving between tracks may be difficult.
Supported formats
From then on, excluding the possibility of introduction of padding, all lossless audio and video file formats are inherently gapless. The following audio/video file formats are available in the gapless internal code.
Other formats do not officially support the gap-less internal code, but some implementations of encoder or decoder may process the gap-less metadata.

3. Some outdated and classic players, such as widows Media Player and Real Player, are usually not popular because the formats supported by these players are not full.

Since there are many companies and organizations working on players on PCs, this also leads to players that cannot be memorized, and some players disappear as quickly as they are available.

4. Quiet listening

This should be the most popular audio player in China. The latest version 5.30beta now supports online listening to music. This feature is quite good, but it is also worth noting that this player has a classic skin, there are several audio effects supported, but some improvements should be made: first, a Comprehensive audio format, such as ape or FLAC, must be supported; second, it is best to support seamless audio playback formats.

5. footbar2000

This player is also a foreign player. It supports more comprehensive audio playback formats and also supports gapless playback, however, I have a superficial analysis of the insufficient skin for this video. Foobar2000 is an audio playback software developed by Peter Pawlowski, a major developer of Winamp. Peter Pawlowski left the Winamp development team due to dissatisfaction with Winamp's development direction. The foobar2000 player is still in the testing stage, but has outstanding sound quality. Currently, apsaravideo player supports audio formats such as ape and MP3.

6, monkey's audio

Mention lossless audio ape, It is not to mention monkey's audio this player, because I do not have how to try this player at ordinary times, here gives its home page linking: http://www.monkeysaudio.com/

7. Some players that support online music, such as cool and cool dogs, can be listened to and downloaded, and are now becoming more and more favored by the Working clusters. I will not introduce it here.

The above is mainly about PC players. As devices on smartphones and mobile digital terminals go deep into the lives of ordinary people, mobile multimedia players have now gained rapid development.

Early mobile multimedia players were combined Based on hardware or software. For example, MP3/MP4, which was popular in year 23, was also proposed as an mp3.5 player, because these chips use dedicated audio/video decoding chips and support a single format, it is almost dusk. Due to the popularity of multimedia players on smartphones, audio and video chip manufacturers will have to switch. For example, sigmtal, once the world leader of MP3 chips, was eventually acquired by freescae. The No1 Zhuhai moments of domestic MP3 chips have also been difficult in the last two years. This shows that the soft solution should be the first choice because the main CPU power of the mobile terminal is powerful.

1. Video dragon Software

In this industry, you may be familiar with Campbell, which is headquartered in Silicon Valley and is committed to becoming a leading provider of mobile multimedia software solutions around the world. Main products please see connection http://www.visualon.com/english/Products/VisualOnStudio.htm

Its main products have been used by several smart phone manufacturers, and the company has many Senior Audio/Video/speech/image CodecAlgorithmAndCodeLevel optimization experts, and domestic expert level direcshow filter enginner. The company's related products support the current comprehensive audio and video formats and the lowest playback power consumption.

2. Apple iTunes

The popularity of Apple iPod and iPhone has become a popular fashion, which also makes the corresponding payer popular, but for a variety of more complex reasons, currently, the iPhone has not been promoted in China, and there are many iPhone counterfeits on the market.

In addition, there are many non-mainstream mobile players or related solutions. I will not introduce them here one by one. If you think that the player is excellent, you can recommend it to me in the message, I want to complete this article.Article. The final statement states that the player mentioned in this article is mostly used by me and is evaluated by industry personnel.
