Does ClickFix work with Audition CS5.5 and later?

No.

ClickFix is an XFM plug-in. Starting with CS5.5, Audition no longer supports third-party XFM plug-ins like ClickFix. It supports only VST plug-ins.

This is unfortunate because ClickFix needs and takes advantage of capabilities provided to XFM plug-ins that are not available to VST plug-ins.

I have no plans at this time to develop a VST version of ClickFix.

Adobe Audition includes a Click/Pop Eliminator.  Why would I use ClickFix instead?

  • ClickFix is much faster than the Click/Pop Eliminator in Audition and Cool Edit. You can get comparable results with ClickFix in less than one-tenth the time.
  • ClickFix has Real-time Preview -- Click/Pop Eliminator does not.
  • ClickFix has a Keep Only Clicks setting -- Click/Pop Eliminator does not.
  • ClickFix optionally displays a detailed summary dialog after processing completes -- Click/Pop Eliminator does not.
  • ClickFix is easier to use. The presets work as-is for the vast majority of cases.
  • Both give excellent results. However, with ClickFix you'll spend much less time adjusting settings to get those results. There are fewer settings to adjust, and the settings are very forgiving.
  • Both let you repair single clicks and other short defects individually.

Which versions of Adobe Audition work with ClickFix?

ClickFix works with Adobe Audition 1.0 through 3.0. ClickFix does not work with CS5.5 or later.

Does ClickFix work with Cool Edit 96?

No. ClickFix works only with Cool Edit 2000 and Cool Edit Pro 1.2 or later. Cool Edit 96 does not support plug-ins like ClickFix.

Does ClickFix work with Cool Edit 2000?

Yes. Both versions of ClickFix 3.04 are compatible with Cool Edit 2000.

Does ClickFix work with Cool Edit Pro 2.0 and 2.1?

Yes. Both versions of ClickFix 3.04 are compatible with Cool Edit Pro 2.0 and 2.1. Previous versions of ClickFix were not compatible with Cool Edit Pro 2.0 and 2.1.

Can I use ClickFix if I already have other plug-ins installed?

Yes. You can install and use ClickFix along with other plug-ins.

Does ClickFix run under Linux with Wine?

Yes.

Also, the versions of Cool Edit and Adobe Audition that support ClickFix work well under Wine.

One problem you may encounter is that the time display is blank in Cool Edit or Audition. This happens if the Microsoft Sans Serif font is missing from your Linux installation. To fix this, copy this font file (micross.ttf) from a Windows installation (typically in C:\Windows\Fonts) to the appropriate Linux font folder (example: /usr/share/fonts/truetype).

Why should I register?  How much does it cost?

ClickFix Free is freeware. You can download it, install it, and use it for free.

You can use ClickFix (full version) for as long as you wish before registering. However, until you register, you are limited to processing up to 30 minutes of signal per Adobe Audition or Cool Edit session, and you can use Force Fix up to 30 times per Adobe Audition or Cool Edit session. When you register, you will receive a Password (as an email attachment) to "unlock" the software. This will remove the limits, and allow you to use the software indefinitely. Your registration will be effective for all future releases of ClickFix (full version), so there are no costs to upgrade.

I am a registered user of an earlier release of ClickFix (full version).  Do I have to register again?

No. Your registration is effective for all future releases of the same version of ClickFix (full version). There is no cost to upgrade to a later release.

What technique does ClickFix use to detect clicks and pops?

ClickFix uses a proprietary statistical detection technique to locate clicks and pops. It does not use edge detection or spectral analysis. This special technique results in much faster and more accurate click and pop detection than other methods.

The method ClickFix uses is equally effective in both loud and soft passages, so there is no need for settings to adjust behavior based on signal amplitude.

With some other click and pop removal tools you may get better results if you first reverse the waveform before processing. This is not necessary with ClickFix. The ClickFix algorithm is symmetrical. That means that the results will be of equal quality whether or not you reverse the waveform before applying ClickFix.

What technique does ClickFix use to repair clicks and pops?

ClickFix analyzes the waveform in the immediate vicinity of the click, constructs an appropriate replacement fragment, and then replaces the click with this fragment.

ClickFix does not use linear or polynomial interpolation nor does it use frequency analysis to construct a replacement fragment. The method it uses ensures that the replacement is as close as possible to the signal fragment damaged by the click.

Does ClickFix use any kind of equalization, such as band-pass or band-reject filtering?

No. ClickFix repairs only those parts of the waveform damaged by clicks and leaves the rest of the signal completely unchanged. This means ClickFix won't dull the sound or introduce undesirable artifacts, as some other click and pop filter plug-ins can. If you wish to use Audition or Cool Edit to perform additional noise reduction, the choice is yours.

Does ClickFix support 32-bit processing?

Yes. Both versions of ClickFix process 32-bit signals using true 32-bit floating-point math, and 16-bit signals using 16-bit integer math.

How do I remove "crackle" from LPs?

Refer to the Tips and Tricks page.

Why do I sometimes hear a "thump" in the signal after using ClickFix?

The "thump" is usually the remnant of a repaired click, typically a large one. It is caused by damage to the signal surrounding the click. ClickFix (or other declicker) removes the click, exposing the thump. If you listen to the signal before ClickFix, the thump is there, but it is masked by the much louder click.

It is difficult, if not impossible, for a declicker like ClickFix to determine whether the signal on each side of the click is damaged (part of a thump) or part of the original signal if it doesn't bear the characteristics of a click. So, it leaves the surrounding signal as-is.

You can often avoid this problem by using ForceFix to repair the click rather than letting ClickFix repair it automatically.

What happened to the ClickFix toolbar button in Audition 2.0 and 3.0?

Starting with version 2.0, Adobe Audition no longer supports toolbar buttons for third-party plug-ins like ClickFix.

As an alternative, use the Favorites feature in Audition or Cool Edit to define a hot key combination for ClickFix. To do this, select Favorites / Edit Favorites. I use Ctrl-Shift-C.

ClickFix does not display as a menu choice in Audition or Cool Edit. What might be the cause?

You can try turning Data Execution Protection (DEP) OFF in Windows for Audition or Cool Edit.

For information about DEP, see:

NOTE: You should turn DEP off ONLY if ClickFix does not display as a menu choice. Otherwise, it is better to leave it turned ON.
