What does the sensitivity number mean?

It is a threshold multiplier between 3 and 12, and it works backwards from what you might expect: lower values catch more events because the bar an event has to clear is lower. The default of 6 is a middle setting, so start there and move down one step at a time if ticks survive, or up if real transients start sounding clipped.

How does the tool decide what counts as a click?

By comparing each sample with the median of its neighbours and judging that residual against a robust estimate of the local scale. Because the test is relative to the neighbourhood, the same setting behaves sensibly in a quiet passage and a loud one, and it does not need a level threshold tuned per file.

Does the repair leave an audible hole?

No. The affected window is replaced with a cubic Hermite curve whose tangents match the waveform on both sides, so the splice rejoins without a step or ringing. Measured behaviour is that the repair stays within bounds and that samples outside roughly six samples either side of the event come back completely unchanged.

Can it clean up worn vinyl crackle?

Only partly. Sparse ticks and pops are exactly what it is built for, but heavy wear produces a dense texture of very small clicks that a detector tuned for isolated events will not address. Light pressure here plus the hiss filter, or a better copy of the record, gets you further than pushing the sensitivity down.

Is it safe to run on studio recordings?

It is safe in the sense that clean signal passes through untouched, but it will act on genuine transients if you set the sensitivity low enough, because a snare hit and a click are both sudden broadband events. Use it on studio material only when you can hear specific defects you want gone, and check percussive passages afterwards.

Click and Pop Remover repairs the sharp ticks and thumps that vinyl and dirty electrical contacts leave behind, by finding them and splicing them out. Detection is local and repair is surgical, so clean stretches come back byte for byte identical.

What is Click & Pop Remover?

Load a file, set the sensitivity and the tool scans each channel for impulsive events, performs a click repair on each one and reports how many it found. It is designed around the shape of the damage rather than the material, which is why it can work on a vinyl transfer and on a clean digital recording with a handful of stray ticks without any retuning.

What it gives you:

A sensitivity slider from 3 to 12, defaulting to 6, where lower numbers catch more events.
Detection by comparing each sample against the median of its neighbourhood and against a robust local scale estimate.
Repair by a zero-tangent cubic Hermite splice, which replaces the event and rejoins the waveform smoothly.
A report line with the total number of clicks repaired across all channels and the sensitivity used.
A WAV download named after the source with a declicked suffix.

The detection works on a seven-sample median residual: each sample is compared against the median of its immediate neighbours, and the size of that residual is judged against a robust estimate of the local scale rather than against a fixed threshold. That is what lets the same sensitivity cope with a quiet acoustic passage and a loud chorus, because the test is relative to the neighbourhood rather than to the file as a whole. When an event is found, a short window around it is replaced with a cubic Hermite curve whose tangents match the surrounding waveform, so the repair rejoins with no step and no ringing. The verified behaviour is that a single full-scale impulse is repaired within bounds and the signal is byte-identical outside a window of about six samples either side, which is why the tool is safe to leave switched on for a whole side of vinyl.

Where it is the wrong answer:

Very wide flat-topped bursts, such as a chopped note head or digital dropout, look nothing like a click and are better fixed by hand.
Sibilants and true transients such as snare hits are loud and abrupt, so an aggressive sensitivity setting can start shaving real musical attacks.
The repair is local, so it cannot restore information that was lost across a long stretch of damage.
Detection runs per channel, so a stereo event that appears in only one channel is reported once and repaired only there.
It does not remove the crackle bed of badly worn vinyl, which is a dense texture of many tiny clicks and pops rather than a series of isolated events. Treat it as a declicker rather than a restorer: it fixes the events a listener would point at, and leaves the general character of the surface noise alone.
The count in the report tells you how many events fired, not how audible they were, so a high number can be trivially correct or over-eager.

Use it on transfers from vinyl, tape and old hardware where the damage is impulsive, and lower the sensitivity only when you can still hear ticks in the result. If snare drums or plosive consonants start sounding softened, you have gone past the point where the detector distinguishes damage from performance and the setting needs to come back up.

How to use Click & Pop Remover

Load the recording and set the sensitivity from 3 to 12, remembering that lower values catch more events.
Run the pass and read the report line to see how many clicks were repaired.
Listen to a passage you know had ticks to check they are gone, and to a percussive passage to check nothing was shaved.
Adjust the sensitivity in one step increments and re-run if either check fails, then download the declicked WAV.

When to use Click & Pop Remover vs related tools

Click and Pop Remover is for isolated impulsive damage, which makes it the natural partner of a vinyl transfer. Clipping Distortion Remover addresses a different failure, where a waveform was flattened by too much level rather than punctured by a tick, and Hiss Remover clears the steady bright noise that usually accompanies the same old recordings. When the noise is broadband rather than impulsive, Noise Reducer works across the whole spectrum instead of hunting individual events.
