Tutorial
NotchDSP removes static and hiss from Suno & Udio exports in your browser. The Guided path is enough for almost every song — Advanced stays tucked away until you need it.
Your audio never leaves this device. Cleaning runs locally in the browser.
Four decisions. That’s the whole primary UI.
Starts you with a known-good mix of strength and options. Switches to Custom when you change things by hand.
How hard the cleaner works. Midrange (~40–60%) is usually best for full mixes. Push higher only if noise remains.
Keeps low end and attacks from getting soft while the rest of the mix is cleaned. Leave on for most songs.
Optional polish after cleaning — gentle EQ, glue, loudness toward about −14 dB. Skip if you’ll master elsewhere.
Light cleanup when you want less noise without changing character much.
Adaptive cleaning plus hiss control, with bass/drums protected. Best first try for complete AI songs.
Stronger floor for isolated vocals or single-instrument stems.
Skips heavy denoise and runs Studio Master alone.
Open the quiet Advanced disclosure when you need module-level control, regions, or core count. You don’t need it for the happy path.
Static for flat hiss, Adaptive for full mixes, Stem for solo vocals/instruments. Aggression mirrors Guided Strength.
Turn on only what you hear. Hiss for sandy top end; Click for pops; Hum for 50/60 Hz buzz.
Sub-bass protect and Drum Snap match the Guided protect flag. More cores = faster jobs and more RAM — phones should stay at 2.
Mark waveform sections and clean them with different settings — useful when only an intro or outro is noisy.
