Both BWAV and WAV files use the .wav extension (some programs use .bwf). They both refer to the same audio format. The main difference is that BWAV files include more information in the file header than WAV files. So, for example, a BWAV file will include “time stamp” information, which allows a software application to place the audio files in the correct position in the timeline.

If a given software application can not read the extra information stored in a BWAV header, it will still read the actual data contained within the file.
