WAV files are resource Interchange file formats (RIFF), including a number of named blocks that contain header information, such as a sound sampling format, or data (such as the sample itself). The Win API provides functions such as turning off Fiff files, finding blocks, and so on. The names of these functions begin with "Mmio". The DirectSound API does not include methods for writing WAV files. However,

This uses FAAC to implement AAC encoding. In addition, the data segment of WAV is PCM, the code will appear many PCM abbreviations. 1 Download and install FAAC The installation process here is implemented on MAC and Linux, and windows can be similar to the reference. wget http://downloads.sourceforge.net/faac/faac-1.28.tar.gz tar zxvf faac-1.28.tar.gz cd faac-1.28 .

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
