Remove Clicks & Pops in Audacity: AI Music Repair Guide (2026)
Share
One click can ruin an otherwise usable AI music render. That does not mean you should regenerate the whole song—or run aggressive cleanup across the entire track.
First identify the artifact. An isolated click, repeated pops, rapid crackle and broad digital distortion are different problems, and Audacity gives you different tools for each.
First: identify what you are actually hearing
One sharp click or pop
Start with a very small local repair. Audacity's Repair effect is often a better first choice than processing a large section.
Several obvious clicks
Click Removal can make sense when transient clicks are spread across a larger selected region.
Rapid soft crackle
This behaves more like repeating background contamination. Noise Reduction may be a better fit than Click Removal.
Broad glitch or distortion
Do not assume Click Removal can rebuild damaged audio. A local edit, replacement, re-export or source-level fix may preserve the song better.
Do you need to normalize before removing clicks?
No. Normalization is not a required first step. In fact, a loud click can influence peak-based level processing, so repairing obvious transient defects before final level work is often the cleaner sequence.
If your actual problem is level—not clicks—use the dedicated Peak vs Loudness Normalization guide. Do not use normalization as a substitute for repair.
A safer Click Removal workflow in Audacity 4
There is no universal Threshold or Max Spike Width
The old version of this guide recommended fixed values. That is the wrong mental model for AI-generated audio.
Threshold
Lower = more sensitive. You may catch softer clicks, but you also increase false detections. Higher = less sensitive. You protect more wanted material, but may leave clicks behind.
Max Spike Width
Higher = allows wider detected spikes. That can help with wider defects, but it can also mistake wanted transients for damage. Use the smallest intervention that solves the audible problem.
The winning setting is not the biggest cleanup. It is the least processing that removes the defect without making the music worse.
If Audacity says Click Removal was not effective
Do not immediately force stronger settings. First confirm that Click Removal is the right tool. If it is, try a larger selection, carefully lower the Threshold, or carefully increase Max Spike Width.
If the click is isolated, switch approaches rather than fighting the algorithm.
For one isolated click, use Repair
Click, crackle, glitch or clipping? Use the right first tool
Lowering gain after clipping does not restore the waveform that was already lost. Likewise, a broad AI generation glitch usually needs more than click detection. Diagnose first; process second.
Where click repair belongs in the finishing workflow
A cleaner order is:
Choose the best source → repair obvious clicks/glitches → reduce noise only if needed → tonal/mix work → limiting/mastering → loudness and export checks.
That sequence prevents a small artifact from driving later processing decisions. It also keeps you from treating every generated song with the same chain.
Fix the whole track without turning cleanup into guesswork
If the click is only one problem in a nearly finished song, use the complete finishing workflow to decide what actually needs repair before release.
Finish the track in the right orderStop fixing every song as if you are starting from zero
If each generation sends you into a completely different repair process, the deeper need is not another Audacity setting. Build a clearer creative lane and a repeatable decision process so you know what is worth keeping, what should be regenerated, and what deserves finishing.
