Why Convert MULAW to WAV file?

MULAW (mu-law) is a compressed audio encoding used in telephone systems, especially in North America and Japan, to carry voice efficiently over phone networks. Converting MULAW to WAV gives you the audio in an uncompressed, universally supported format that recording software, editors, and players work with directly.

WAV is widely accepted, so a phone recording or voice file in the mu-law encoding becomes usable on any device. Keep in mind that mu-law is speech-focused and compressed, so converting will not add quality, but it makes the recording playable and editable everywhere. It is the reliable way to bring telephony audio into standard tools.
