WAV is a lossless sound file under Windows, the file holds the audio PCM information and the player plays that music when most information is made, he has two blocks, the first block is the format block, the second block is the data blockFirst, the format block, the format block with a picture can be explained, as followsUsing Winhex to analyze a WAV audio file, Han Lei's farewell message is as followsBy co

value is the number of channels × the data bit value per sample/8. The playback software needs to process multiple bytes of data of this value at a time to adjust the value for the buffer zone. 22 h 2 　 The number of data digits of each sample, indicating the number of data digits of each sample in each channel. If multiple channels exist, the sample size is the same for each channel. 24 h 4 Char DATA tag "data" 28 h

Another product of the company, when monitoring CTI, the recording format is PCM.To play in IE, You need to convert it into a standard WAV. previously, I used a com library for conversion. Now I can't use that library for various reasons (64-bit support is not good), So I implemented it in Java. The basic code is as follows.In fact, WAV is only a PCM file with the relevant file header and description inform

There are two types of audio recording in Android: audiorecord and mediarecorder. The former is suitable for real-time processing of audio data. The latter is suitable for storing audio and video locally. However, the latter seems to only store MPEG4, Amr, and 3GPP media formats. Why do they be saved to WAV format? It is best to have a ready-madeCode. Of course, if you tell me to use audiorecord to retrieve byte streams and splice them into

If this problem occurs, search for historical data as usual. One clue was found: "merging through WAV file format" Let's take a look at the wav file format first. Obviously, subchunk2size indicates the audio data size. If the format is the same, try to merge the data area. Of course, the subchunk2size audio data size and file size chunksize need to be recalculated Type Twavformat =Packed Record Chunkid:Ar
