Listen for the details
The best setting is not always the highest one. Leave some room for louder moments in the recording, and reduce the gain if the result sounds harsh or squashed.
Make one change at a time. Reset all takes the controls back to their starting settings whenever you want a fresh comparison.
Before you save
Will this remove background noise?
No. Raising the gain also raises background noise already in the recording. Use a clean source when possible.
Can I make a recording quieter too?
Yes. Move Output gain below 0 dB to lower its level. Reset all returns the gain to the tool’s starting setting.
How do I compare the two versions?
Use Original and Processed above the settings. Click a waveform to revisit the same part of your recording.
Which download format should I use?
Choose WAV for further editing, or MP3 or AAC for a smaller file. The bitrate controls the size and quality of MP3 and AAC exports.
