15.75 WAV files
WAV (Waveform Audio File Format) is an audio file format. Although a WAV file can
hold compressed audio, the most common WAV format contains uncompressed audio in
the linear pulse code modulation (LPCM) format.
Developed by Microsoft and IBM, WAV is closely related to AIFF and is compatible with
Windows, Macintosh and Linux operating systems. Uncompressed WAV files are quite bulky,
but they have a simple file structure which can be processed efficiently in audio editing and
produce archive files of high quality. 8-, 16-, 20-, 24-bit and 32-bit (float) resolutions are
supported.
The file extension is .wav
