What changes when you convert MP3 to WAV
- WAV is uncompressed, so the file will be much bigger than the MP3 (about 10 MB per minute of stereo) – that's normal.
- WAV can't add back detail the MP3 didn't have, but editors and DAWs handle it without any decoding problems.
About MP3 and WAV
- MP3 is the audio format every phone, car stereo, speaker, editor and website accepts. It's lossy, so files are small.
- WAV is uncompressed audio – exact quality, but about 10 MB per minute of stereo sound. Audio editors, DAWs and some upload forms ask for WAV.
Tips for Mac
- Works on Apple silicon and Intel Macs alike – nothing to download from the App Store.
- The file is decoded by your browser's built-in audio support. If one browser can't open it, try Chrome or Firefox.
