WAVE_HEADER Field - usBlockAlign

usBlockAlign (USHORT)

Block alignment, in bytes, of the waveform data. Playback software needs to process a multiple of usBlockAlign bytes of data at a time. This value can be used for buffer alignment. It should be determined by the following formula for audio presentation format of standard PCM data:

   usChannels x usBitsPerSample /8
