I find it valuable to repair the low frequencies too in speech (certain lip-closing thumps and rattles in the sibilants get removed) but the lower frequency bands do take more computation time. Impatient for results? Use fewer bands, or raise the bottom of the range. Both tools specify a range of frequencies and a number of frequency bands (of equal width in log-frequency) for detection and repair.I don’t do any of this once I find settings I trust. You might silence corrections you don’t want before mixing. If you duplicate a track, then isolate changes in one, you can listen to the tracks together to hear the repaired sound (the isolated clicks interfere destructively), or mute one to hear just the original or just the subtractions.You may notice that the attack of many consonants is somewhat affected, but you might judge that this is acceptable and sometimes even helpful. You don’t want to hear a lot of “murmur” so that you almost understand the words: your settings are taking overtones out of your vowels and muffling the voice. Or, choose Isolate Changes to hear only what is subtracted from your signal. In either tool, choose Apply Changes to hear just the results.(I’ll blame garbage collection.) But I have improved performance much over the previous version.Īs mentioned below, do low-frequency rolloff (highpass filtering) before De-Clicker for slight improvement of some results. Compute time does unfortunately go nonlinearly with length of the track to some extent. I treat typically no more than a half hour at once. So select it and fix it and move on, don’t fuss with zooming in and out. The surrounding signal is usually unaffected. Yet the nice thing is that you do not have to select the interval around the click very narrowly. But such settings may be too slow and too aggressive for batch treatment. I successfully treat most of the more resistant clicks by hand with a single pass and double the number of bands: NOT by lowering the dB threshold control. Do you have different opinions about good default settings? Let me know. The default settings in both tools are the ones I favor now for treatment of whole tracks. I did not intend this for music or vinyl repair, but I would like to hear whether it has unexpected other uses. DeClicker).Īs written by the autor, De-Clicker is designed for filtering of natural but undesirable noises that take a few milliseconds to decay, not for repairing spikey damage to a digitized signal. Possiblyįinally, from the Effects menu item, select Add/remove plug-ins: you can choose to select all pug-ins and activate all of them or select New and enable the ones you want to add (e.g. by default C:\Program Files (x86)\Audacity\Plug-Ins ). Then you have to put it among other available plug-ins in the proper Audacity program directory (i.e. De-Clicker).įirst you need to download the plug-in for example from an post of the Audacity forum. In the following there are some screenshot that show how to import and use a new plug-in (e.g. As an payment alternative (limited free use): GoldWave or Sound Forge Audio Studio. The following link allows you to add the LAME MP3 encoder – so allowing Audacity to export MP3 files. For example you can find a De-Clicker and new De-esser for speech plug-ins that you can add in Audacity in order to use some them. Plug-Ins) that you can download to use additional effects and filters: you can find even more looking into its forum. I already said that it is a free multi-track audio editor and recorder ( for Windows LADSPA plug-ins 0.4.15 installer. In my post Nice tools/services (for free) … and other useful links I already listed Audacity as a very nice tool.
