![]() ![]() ![]() ![]() Although these formats are also standard wav, the formats are slightly different. However, in the modern wav file, in addition to the 44 bytes, there are many extended formats. Where w_fileid is a fixed string RIFF, 4 bytes, and the next 4 bytes w_chunksize is the size of the entire file. The above formats are compatible with all wav formats. Uint32 w_datachunksize /* length of data chunk */ Uint16 w_nbitspersample /* number of bits in a sample */Ĭhar w_datachunkid /* data chunk id 'data' */ Uint16 w_nblockalign /* number of bytes per sample */ Uint32 w_navgbytespersec /* average bytes per second */ Uint32 w_samplespersec /* sample rate in hz */ Uint16 w_nchannels /* number of channels */ Uint16 w_fmttag /* format tag, 1 for PCM */ ![]() Uint32 w_fmtchunksize /* format chunk size */ This may not always be true.įor the wav header of a PCMWAVEFORMAT, we can usually understand that a structure as follows is at the front, and then followed by pure PCM, the format is as follows:Ĭhar w_waveid /* wave chunk id 'WAVE' */Ĭhar w_fmtid /* format chunk id 'fmt ' */ Usually we use data to eliminate the header information of wav files, and then assume the rest data is PCM. ![]()
