Tunedzy Repair
Updated October 2026
Repair is Tunedzy’s set of targeted fixes: flat-topped clipping, clicks and crackle, mains hum, and DC offset. It runs before the cleanup and reports what it changed.
The short version
- Clipping repair rebuilds flat peaks at the file’s own sample rate.
- Click repair mends short spikes and crackle.
- Hum repair notches the mains frequency and its harmonics.
- DC offset is removed so the wave sits around zero.
Clipping
Flat-topped sections of a waveform are found and rebuilt from the curve around them. The repair works at the file’s own sample rate, so a 48 kHz phone file is repaired correctly. Heavy clipping cannot be rebuilt reliably.
Clicks and crackle
Short spikes that stand out from the voice are replaced with the sound around them. Use the lowest setting that removes them.
Hum
Mains hum at 50 or 60 Hz and its harmonics is notched out. The hum guide explains the method.
DC offset
A DC offset shifts the wave away from zero, and it can make a file look louder than it sounds. It is removed.
Repair first, then clean
Repair runs before the cleanup in Perfect it, and tells you what it changed.

Frequently asked questions
Does Repair change the voice?
It changes only the faults it finds. Compare Before and After.
Why does Repair report clipping in my file?
It found flat tops in the waveform. Repair rebuilds what it can.
Can Repair fix every click?
It fixes most short clicks. Recurring clicks point to a fault to fix at source.
