How to convert MP3 to WAV
Some editing apps, phone systems and hardware samplers require WAV. Converting MP3 to WAV gives them an uncompressed file they accept.
- Drop your MP3 file into the box above, or add it from a link.
- WAV is already selected. Use the settings button next to it to change size, quality or other options.
- Select Convert, then download your WAV file.
To do this from your own code, call the FileForge API with "output_format": "wav".
Good to know
- The WAV will be about 10 times larger, but it won't sound better than the MP3: lost detail can't be restored.
- Set the sample rate if your target needs a specific one (phone systems often want 8 kHz mono; use the channels setting for mono).
About the formats
.mp3
MP3 is the universal audio format: every phone, car stereo, speaker and app plays it. It uses lossy compression, so a 3-minute song is a few megabytes.
.wav
WAV is uncompressed audio, as recorded. It's the standard for editing and for software that needs raw sound, but files are about ten times bigger than MP3.
Questions
Does WAV improve MP3 quality?
No. It stops further loss when you edit, but the sound is the same as the MP3.
