Why you sometimes need a WAV
MP3 is perfect for listening to music, but some systems don't accept it. Phone systems and menus (IVR), some editing programs, audio consoles, drum machines and many radio platforms ask for WAV, because it's an uncompressed format any device can read without decoding.
This tool converts your MP3 into a 16-bit PCM WAV with the same sample rate and channels as the original, which is the most compatible setup.
Most common uses
Audio and video editing
Some editors work better with WAV, because it allows exact cuts without decoding the MP3.
DJ and production gear
Samplers, drum machines and some controllers only read WAV from a USB drive.
Platforms and contests
Radio stations, distributors and music contests usually ask for material in WAV.
What to know before converting
WAV is much bigger. A minute of stereo audio in WAV takes about 10 MB, versus 1 to 2.5 MB in MP3. That's normal.
Quality doesn't improve. The WAV will sound exactly like your MP3: converting doesn't recover the quality lost when the MP3 was made, but nothing more is lost either.
