"grasping track") to get the WAV file has about 800MB. Such a large file, although good quality but not conducive to transmission on the network! So a variety of compression technology appears, the most famous when the number of "MP3", there are "RM, WMA" and so on, these compression is to some pieces of sampling, belong to the "lossy compression." 320KB MP3 Despite the so-called "close to CD quality", but as long as the access to a slightly better a

So to speak the audio format, CD is naturally the leading pioneer. In most of the playback software "open file Type", you can see the *.CDA format, this is the CD track. The standard CD format, also known as the 44.1K sampling frequency, is the rate 88k/s,16 bit quantization, because the CD

, you can discard MP3 and stop CD directly. CD carries waveform files in a completely lossless format, this will produce better results.If you want to reduce the distortion, increasing the bit rate is the only way. It is best to use a variable bit rate (VBR) to compress the MP3 file to achieve a balance between the maximum fidelity and the minimum file size.Finally, if you want to completely lossless sound

lossless format. 12 Wma WMA (Windows Media audio) is Microsoft's masterpiece in the field of Internet audio and video. The WMA format is a way to reduce data traffic but maintain sound quality to achieve a higher compression rate, the compression rate can generally reach 1:18. In addition,

Audio multimedia files mainly store audio data information, audio files in the process of recording the sound signal, through the audio encoding, into the audio digital signal to save to some format file. During playback, the audio file is decoded, The decoded signals can be turned into sound waves by means of devices such as loudspeakers. audio files are very large in the encoding process, so some file formats compress the data, so the audio file can be divided into:Lossless format, non-compres

, WMA, Ogg is known as lossy compression, lossy compression by definition is to reduce audio sampling frequency and bit rate, the output of audio files will be smaller than the original file. Another kind of audio compression is called lossless compression, which can save all data of the original file in 100% the volume of audio files compressed smaller, but after the compressed audio file restore, to achie

Put too many music files directory series, or the existence of the Android system does not recognize the code3. Memory card problem4.

In addition, the current speed of transmission faster USB3.0 and more than 16G large capacity MP3 is accelerating the popularization, but also make AAC head "small" aura ceased to exist.

From: http://bbs.imp3.net/thread-251659-1-1.html Compared with the MP3 format released in 1990s, Ogg format support is of great significance to MP3 digital music players: first, the memory space of digital music players is limited, while q0 (64 Kbps Bit Rate) the quality of the Ogg music format can be 1/2 kbps bit rate of the MP3 music format. It can fully meet people's daily appreciation requirements and save at least of the storage space. Secondly, the Ogg format of Q10 (500 kbps) quality is b

WMV (Windows Media video) is a group of digital video codec formats developed by Microsoft. asf (Advanced Systems format) is its Encapsulation Format. The WMV file encapsulated by ASF has the "digital copyright protection" function. Extensions: WMV/ASF and wmvhd. ASF (Advanced Streaming Format advanced stream format ). ASF is a File co

encoding decoder to compress and decompress audio signals. Let's talk about its basic process. First, we can record PCM from the microphone. This codec converts PCM into AAC format and writes AAC into a hard disk file, which can be achieved in three steps, in the middle of a codec transcoding process, you will find out how it records the data format. I just talked about codec, but the focus is on codec. We may not have IOS support for recording this codec. Let's take a look at the codec support

have an audio file on our computer, whether it's MP3, WMA or WAV, which is usually a song. We heard a song with the original singing, accompaniment. And the characteristics of the original singing is broadly divided into two: 1, the voice of the audio-acoustic position in the entire sound field of the central (balanced distribution of left and right channels); 2, the sound frequency concentration in the intermediate frequency and the high-frequency p

Compared to VBR and ABR, it compresses the file volume is very large, but the sound quality will not be significantly improved.Lossy and LosslessAccording to the process of sampling and quantification, the audio coding can only achieve the infinite close to the nature signal, at least the current technology is not likely to be exactly the same. This is because the signals in nature are continuous, and the values after the audio en

bandwidth for the audio file format is 20KHZ. According to the Nyquist theory, only if the sampling frequency is higher than twice times the maximum frequency of the sound signal, the voice of the digital signal can be restored to the original sound, so the audio file sampling rate is generally 40~50khz, such as the most common CD quality sampling rate of 44.1KHZ. The process of sampling and quantifying sound is called Pulse Code modulation (modulation), or short PCM . PCM data is the most orig
