A note on MP3 quality
MP3 is a lossy format: every time a file is encoded, a little detail is lost. Re-encoding once at a good bitrate is not something anyone will hear, but for a file you will edit again later, export a WAV and make the MP3 at the end.
If the MP3 has music in it, keep in mind that the noise remover is built for speech and treats music as noise. For a voice over music, switch Noise Suppression off and use the EQ and compressor.
Questions
Is there a free MP3 voice enhancer online?
Yes, this one. Open an MP3, enhance the voice and save a new MP3, free, with no signup and no limit.
Will the enhanced MP3 lose quality?
Encoding once more at a good bitrate is not audible for speech. If you plan to edit the file again, export WAV instead.
Can I enhance the voice in an MP3 with music?
It is built for speech, and the AI noise remover treats music as noise. For voice over music, switch Noise Suppression off and use the EQ, compressor and limiter.
Is my MP3 uploaded?
No. It is processed in your browser and never leaves your device.
Which other formats can I open?
WAV, M4A, OGG, Opus, FLAC and WebM audio, plus recordings made in the app.
