Reaper: Removing audio clicks with sample editing

The REAPER Blog·May 2026

Demo summary

A practical demonstration of using the sample edit tool to silence a sharp click in a noise recording by dragging sample values to zero.

Step-by-step

Identify the sharp click or thump in the waveform
Zoom in closely to the individual sample level
Select the sample points causing the click
Drag the sample values down to the zero line to silence them
Smooth out any discontinuities in the waveform by redrawing adjacent points

Options

Keep the low end of the waveform while only removing the high-frequency click at the end

Watch out for

Editing at the sample level can be difficult to keep the desired area centered on the screen while zoomed in

Tips

Smooth out discontinuities after silencing a click to prevent new artifacts
Be prepared to draw many individual points, as there are 48,000 samples per second

Highlights

“that didn't take very much time at all, and we've completely gotten rid of that thump”
