Remove Clicks and Crackle from Audio
Vinyl pops, digital clicks and crackle are sharp, isolated spikes. This tool detects each click and interpolates across it, removing the snap without dulling the music underneath.
How it works
A median filter flags samples that jump far from their neighbours — the signature of a click — and replaces only those samples with a smooth interpolation, leaving the surrounding waveform exactly as it was.

Frequently asked questions
No. Only the samples identified as clicks are altered; everything between clicks is passed through untouched, so the music keeps its tone.
Dense crackle is handled by the same detector at a tighter setting. For a hissy surface noise underneath, follow with the hiss-removal tool.
Yes — sample-level digital clicks look the same to the detector as vinyl pops and are removed the same way.
The detector targets spikes far shorter than musical transients, but very percussive material can trigger false positives, so use a gentler setting on busy drums.
Yes. Left and right are de-clicked separately, since vinyl pops rarely strike both channels in exactly the same place.
No. Click detection and interpolation are fast CPU operations that run quickly even on a full album side.
Yes. A lossless WAV or FLAC transfer gives the detector cleaner samples; MP3 compression can smear the sharp edges of a click and make it harder to flag.
