What is WAV?
WAV is an uncompressed PCM audio format from Microsoft and IBM. It stores every sample exactly as recorded, which makes it the standard interchange format for audio editing, sampling, and CD-quality mastering.
Why convert MP3 to WAV?
Some editors, samplers, DAWs, and hardware players only accept uncompressed PCM. Converting to WAV gives you a lossless working copy — though it cannot restore detail the original MP3 compression already discarded.
Quality & size notes
The output is 16-bit PCM WAV at the source sample rate. Expect files roughly ten times larger than the MP3, since WAV stores audio without compression.
