Audio Cleanup Studio
Remove background noise, cut silent gaps, shape bass and treble, add fades, and match the loudness streaming platforms expect. Everything runs on your device — nothing is uploaded.
Your files
Joins your files one after another, in the order above, into a single track you can then clean up as usual.
Selected recording
Selected noise sample:
Zoomed in, drag left and right on the waveform to scroll, and drag up-down-and-across on it to select a noise sample precisely.
Settings
These apply to whichever file is selected above, and to every file if you process them all at once.
Higher removes more noise, but can make voices sound thin or watery.
Auto works well for steady hiss or hum spread through the file.
Anything quieter than this is treated as silence. Raise it (toward -20 dB) if a noisy room is still catching gaps; lower it (toward -70 dB) to only catch true silence.
Only gaps at least this long get trimmed, so quick pauses between words are left alone.
How much of each silent gap to leave in place, so cuts don't feel abrupt.
Cutting treble can also soften leftover hiss; boosting it adds clarity and air.
Sets the file's overall loudness to the target and keeps peaks at least 1 dB below full scale, so it won't sound distorted or get turned down further by the platform.

How it works
- Noise reduction learns the sound of your background noise from a short sample, then subtracts that pattern from the whole file. Works best on steady noise: hiss, fans, air conditioners, road drone, hum.
- Remove silence finds gaps quieter than your threshold and cuts the middle out of any gap longer than your minimum length, leaving a little padding so it doesn't feel abrupt — the same idea as Audacity's Truncate Silence.
- Bass & treble and fades work like a basic mixing desk: shape the tone, then smooth the very start and end.
- Match streaming loudness measures your file's loudness and adjusts the volume to match what Spotify, YouTube and other platforms expect, so your track isn't turned down or up unexpectedly.
It can't separate one voice from another or remove sudden sounds like horns and claps, and heavy noise reduction can make speech sound underwater — start around 50–70% and compare the two players.
