My MP3 Sounds Worse Than My WAV
Updated October 2026
MP3 is a lossy format, so it removes detail. A low bit rate or a conversion from another MP3 makes the loss audible. Export from the WAV master at a high bit rate.
The short version
- MP3 removes detail to save space; a low bit rate removes more.
- Converting an MP3 to another MP3 adds loss each time.
- Export from the WAV master at a high bit rate for speech.
- Keep the WAV as the master, and export MP3 only when you need it.
Why MP3 loses detail
MP3 removes sound the ear is supposed to miss, to make the file small. At a high bit rate, most listeners cannot tell it from the original for speech. At a low bit rate, artifacts show on sibilance, breath and room sound.
Why conversions add up
Every lossy conversion removes more detail. Converting an MP3 into another MP3 is the worst case. Always export from the lossless master.
How to export a better MP3
- Start from the WAV master, not an earlier MP3.
- Choose a high bit rate, the highest your platform accepts.
- Check the true peak of the exported file, because conversion can raise it.
When WAV is better
For editing, for handing to another editor, or for platforms that accept WAV, keep the WAV. The format guide explains the choice.
Export from the master, not a copy
Tunedzy keeps the master and exports MP3 from it, so the file is not a copy of a copy.
