Noise reduction is always a compromise because, on the one hand, you can have all the music and a lot of noise and, on the other hand, no noise and only some of the music. Frequency smoothing (bands) - no more than 6 (3 or lower is a good setting for Music).Noise reduction - no more than 12 dB (9 dB is a good guideline).If it is OK, undo the amplify, then re-apply the Noise Removal effect with these recommended settings: Try amplifying the sample and audition it to ensure that no real audio signal is present. The length is not important but, typically, it will be less than a second what is important is that you have a true representative sample of the noise without any audio signal at all (such as a very quiet fade lead in). Use the Noise Reduction effect's Get Noise Profile to obtain a noise sample from either the lead-in grooves immediately before the music starts, or from a lead-in between tracks. Whether you need to use Noise Reduction will depend on the quality of your LPs, your stylus and cartridge. Also see further down this page for a set of alternative tools known to work well in removing clicks and pops. See Click and pop removal techniques for a detailed tutorial on these tools. You do not need to be zoomed in so far as to see the individual samples, but the silenced sections must be short enough so as to not be audible. Edit > Remove Special > Silence Audio.Some patience may be needed with this tool, but the principle is to put samples back into line with their neighbors so that a smooth contour is presented. You need to be zoomed in to the individual samples to use this. For somewhat longer regions of audio, try:.For hard to spot clicks you may want to try Click removal using the Spectrogram view.You will need to zoom in to see the individual samples to use this effect. This repairs a very short length of up to 128 samples by interpolating from the neighboring samples. These methods are only really useful if you have a relatively small number of clicks and pops to deal with otherwise, these approaches will be too labor-intensive and time-consuming: Then, using the settings from your preview testing, use the Click Removal effect on selected regions of audio or on the whole project.Ĭlicks which did not get removed with Click Removal can be treated individually with other methods. After determining that your selection indeed needs to have clicks removed use the Click Removal effect with various settings - preview the effect with these different settings to get the best results. Select a region with one or more of these spikes and listen to it to ensure that they are clicks. First, without zooming in too far, visually inspect your recording for clicks - they will show up as abnormally tall (sticking up or down), very narrow (one or two pixels wide) vertical lines protruding from the waveform. There are a number of ways you can use Audacity to remove clicks and pops from your recording. Reduce subsonic rumble and low frequency noise. #Best clickrepair settings software#While all of the processing in this tutorial is carried out using Audacity, some users may prefer to use alternative software for specific sub-tasks like noise removal and the removal of clicks and pops (Audacity's Click Removal may not give as good a result as other software).įor more details of the steps involved in this workflow please see the tutorial set Copying tapes, LPs or MiniDiscs to CD. Your final goal will be to export WAV files for CD creation or other file formats which might be more suitable for your needs. This workflow does not at any stage necessitate the saving of an Audacity project (though you may wish to do that if you need to interrupt your work). There is no fixed " right" way of working - there are many alternatives like any recipe, it can be adapted to suit your personal needs. #Best clickrepair settings portable#This tutorial outlines a set of example steps using Audacity to digitize LPs to create files that are ready for CD creation, loading into a digital jukebox or portable music player.
