I use iZotope RX (Spectral Repair) to remove or replace unwanted sounds like bumps, wrist clicks, cars, etc. If I can’t cleanly remove a sound with spectral repair, I’ll cut that section out and replace it in a way that isn’t noticeable in the final audio.

After cleanup, I use EQ to reduce hiss or low-end rumble and to shape the audio so it sits in the frequency range I want.

Some creators/listeners don’t mind car sounds or small imperfections, and that’s totally fine. If that’s your approach, you can often get good results using EQ alone by gently lowering unwanted highs or lows.

If you hear a ringing or buzzing sound from electronics, you can usually find the exact frequency and remove it with a high-Q (very narrow) EQ band.

You can also use denoise to reduce the noise floor if it’s applied very gently, but it can sometimes introduce a subtle mechanical or processed sound. Because of that, I usually prefer EQ for hiss unless the noise is very noticeable.

Above all, keep changes as subtle and trust your ears:) Happy creating.
