Frequently Asked Questions
Start with Normalize for uneven volume, Hum Removal or High Pass for low rumble/buzz, EQ (Voice) for clearer speech, De-esser for harsh "s" sounds, and the Compressor to even out loud/quiet parts. You can run the result through again with a different enhancement.
No. These enhancements adjust volume and frequencies only — the pitch, speed, and length of your audio stay the same.
It depends on the recording. Files with mild issues (low or uneven volume, hum, slight harshness) improve the most; severely degraded audio has less room to recover.
The result downloads as a WAV file, and you can upload audio up to 10 MB. To convert the WAV to MP3, use our Convert Audio tool.
