![]() It only affects the samples that it identifies as clicks or pops.Īs I explained elsewhere in this thread, Here are the statistics for a 20 minute side of an album : It is not like some sort of filter that affects the entire track. But so long as the threshold setting is used correctly, the music is unaffected. Of course it is possible to set the threshold setting too high so that Click repair falsely identifies fast music transients as clicks and pops. The music is unaffected except where a click or pop occurs. This means the two files are bit-identical except for those very brief times. You will see the result is exactly zero except the few milliseconds where a click or pop has been acted on. Invert one of the files and add the two together. Use a DAW to look at the original file and the file after Click Repair has been used on it. So, export the project as a WAV or AIFF, then open it again in Audacity and you can play with the entire Noise file all at once.Ĭlick to expand.Try the experiment suggested above by John Purlia. When played back or exported, you effectively get a diff of the two files, leaving only the Noise. ![]() Select the waveform of the ClickRepair file and Invert it. You can generate a waveform by creating two stereo tracks in Audacity - the original file, and the file generated by ClickRepair. I find it VERY helpful to look at and listen to the waveform of the noise identified and eliminated by ClickRepair, and make adjustments based on what has been removed. For used albums where I have no idea of how well the album was cared for, I typically look at the waveform in Audacity, and - if I see lots of spikes - begin with a value of 36, which I adjust up or down depending on what the Noise waveform looks like. Using that as a starting point I've been using a value of 24 for LPs I've digitized myself where I know the original album has very little wear. They could be viewed as correcting flaws in the original recording and mastering process which frequently end up on many master recordings. These, on examination, were really minor and very deep in the mix. (Given, this was on a single CD source and a single style of music, so far from a thorough examination)ĭeClick values of between 12 and 25 using the Simple method and Reverse turned ON all yielded about 12-13 false positives combined between the left and right channels. My goal was to find the combination of setting that would yield the fewest number of changes (in theory, the lowest number of false positives. ![]() One of my first tests was to see what would happen when running the software against a source known to not have any clicks - a CD, which in theory doesn't have any audio anomalies typical of vinyl playback. I'm just getting started using ClickRepair, so have been going through all kinds of experiments.
