Description Waveform Audio File Format is a Microsoft and IBM audio file format standard for storing an audio bitstream on PCs. It is the main format used on Windows systems for raw and typically uncompressed audio. The usual bitstream encoding is the linear pulse-code modulation (LPCM) format. The AU file format is a simple audio file format introduced by Sun Microsystems. AU format was common on NeXT systems and early Web pages. Originally it was headerless, being simply 8-bit μ-law-encoded data at an 8000 Hz sample rate. Hardware from other vendors often used sample rates as high as 8192 Hz. Newer AU files have a header that consists of six unsigned 32-bit words.
Technical details Though a WAV file can contain compressed audio, the most common WAV audio format is uncompressed in the linear pulse code modulation (LPCM) format. In addition, audio in WAV files can be encoded in various audio coding formats, such as GSM or MP3, to reduce the file size.
