Klick Detection

Klick detection in audio materials. An easy method.

In Short
a. use a Gain Plugin,
b. invert one channel,
c. make it mono.
Result: clicks are better to hear.

You may use
Gain from Logic Pro,
4U Meter Fader MS-Pan from hofa,
PHA-979 from Voxengo (use mono mix, not force mono),
and others…

What and Where:
On fresh tracks, check for clicks;
After massive effects, check for unwanted clicks;
On a rough mix, check for clicks and imbalances;
Before rendering, check a stem or a bus;
When mastering, check input files.

Clicks in recorded material are mostly from clipping due to too high recording levels. Two best practices to avoid this: use a 32bit-interface, level correctly.
Inappropriate handling of 32bit-files. Use a 32bit cabable editor when importing such files. Not all DAWs can handle them properly.
Popping a sensitive membrane with an explosive burst of air is beyond the capabilities of most microfones. Use a good pop screen (not simply stockings, but double layer very fine weave).
Static discharge. Always be grounded.
Any modeling plugin has some nonlinear behavior. If pushed too hard, clicks might be the result of the modeling process. Know what you are doing (aka know your plugins, know your DAW).
Cuts not made when waveform crosses zero, no fade around cut area.
