What is WAV?
Waveform Audio File Format
WAV is an uncompressed audio format that preserves the original recording bit-for-bit. It's the gold standard for audio editing, mastering and archival work where every detail of the sound matters.
History of WAV
WAV (Waveform Audio File Format) was developed jointly by Microsoft and IBM in 1991. As an uncompressed format, it stores audio exactly as captured — making it the standard for professional recording, editing, and mastering. WAV files are large but lose nothing from the original signal.
