If you want to make a recording sound like it came off aĪ recording from an actual scratchy LP with Keep Only Clicks turned on. Then use Adobe Audition's Mix Paste feature to add those clicks and pops to a clean Lasso selection tools while in Spectral Display view to limit detection andĪdding clicks to simulate the sound of a scratchy LP In Adobe Audition you can use the marquee and Spectral Display view from Adobe Audition's View menu. The click will show up as a narrow vertical line. You can even use ClickFix's Force Fix feature to repair the click This, zoom in on the portion of the waveform that contains the click, then select Locate it in the waveform, switch to Adobe Audition's Spectral Display view. To do If you hear a click you want to repair using In these cases, it's best to experiment and see what works best. Get better results performing at least some noise reduction before usingĬlickFix. However, with extremely dirty signals, you may Them first. The reverse is not generally true - noise typically does not "confuse" the noise reduction process, so it is best to get rid of Performing click removal first, then noise reduction. Clicks and pops can Users sometimes wonder whether to perform click removal before orĪfter noise reduction. In most cases, you'll get better results by To make it easy to call up ClickFix, use theįavorites feature in Audition or Cool Edit to define a hot key combination forĬlickFix. To do this, select Favorites / Edit Favorites. I useĬlick and pop removal before or after Noise Your selection, so make sure you select the entire click plus a few samples on Select each click and press F3 ("repeat last command").ĬlickFix will not change any part of the waveform outside Use ClickFix's Force Fix feature to repair it. To repair more clicks, just Individually, use Adobe Audition's F3 feature. If you prefer to use ClickFix to repair clicks The Sensitivity setting, or increase the Musical Transient Rejection setting. If you hear musical content, you may need to decrease Removing too much from the signal you're trying to clean up, turn on Keep OnlyĬlicks and click the Preview button. This lets you hear what ClickFix will (Full version only) To make sure you are not Set Sensitivity high enough for your particular signal. Sensitivity. You may find that you get better results by increasing the Sensitivity setting. The presets may not In ClickFix (full version), the setting that makes the most difference is But don't be afraid to experiment with the settings to get theīest results with your particular signal. Using this flow, automatic up to clicks 10-20 samples wide (for a hi-res recording at 44.1kHz I put the limit at 10 samples), manual/visual above that, combined with a low detection sensitivity (5 to 10), I can process an album side in 10 minutes or so, while remaining confident in the sonic outcome.The presets that come with ClickFix work well for most are repetitive: when I see such an artefact twice or thrice in a couple of seconds, I know it is the music itself and I omit correction. While there is a preview/prelisten feature I never got to grips with it, but I found after only a short while that many real clicks are visually distinct from real sound, obviating the need for listening! In those cases where it is too hard to see directly what it is, I found that false positives often follow the music's rhythm, i.e. Alternatively, it allows you to edit the repair manually. If the presumed click exceeds that size, the program stops, displays the waveform, and asks you to decide if it is click or music (clicking Accept then makes the repair, while hitting the return key skips to the next click). ClickRepair has a programmable detection threshold, and lets you have automatic repairs done to clicks up to a specified duration or number of consecutive samples. For me it is the only sonically tranparent tool that still allows a reasonably fast workflow. This is part of an article soon to be published at TNT Audio:ĬlickRepair is a shareware application for PC and Mac, written and maintained by Australian retired mathematics professor Brian Davies.
