whether you installed your distribution's release, PPA version, or compiled Audacity from source code. I was afraid of that.
The signal could be anything but a peak: it has time to do lots of things until the clipping stops. Very soft and rapid light ticks that sound like static electricity and which are typical of vinyl (even though the pressing is often the cause rather than a static charge) will not be effectively removed with Click Removal.
A clip event is one tiny blue wave. In general, a clipped source is still a broken source if it is anything more than very minimal clip recovery needed. Silencing highly zoomed areas or redrawing samples can get tedious even over a relatively short stretch of audio. I selected All, then went up to "Effects" and scrolled down to "Normalize". What causes it, and how to avoid it when recording audio? For details of how Audacity's Click Removal works see this page in the Wiki. For broader clicks, move the "Spike Width" slider further to right. Even if there was, it would have to basically be completely guessing at what should be there. 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. When the clipping is showed, there are so many clip-lings that on one the song is almost completely red, and the other is just really loaded with clipping. Move the "Threshold" slider to adjust how sensitive the click detection is, and the "Spike Width" slider to adjust the length of spiked audio to be considered as a click. Which tasks can be visually confirmed by other crew members?
the green one) could have actually happened in the lapse of time we don't have info about. Use Spectrogram view to identify clicks more easily, Check current version of this page (development Manual). If it was actually an analog clip, then it is a similar principal where the circuitry can't process or create a large enough signal. For somewhat longer regions of audio, try: First, select the area of track that has the click, then click in the track name by the downward-pointing arrow to open the Track Dropdown Menu (right). Either way, it would take me days to manually fix them, or even use the clipping tool to fix them. Audacity has a Repair effect which can be used to repair a short length of up to 128 samples long (for most audio, only a few thousandths of a second) by interpolating from the neighboring samples. I've been combing my music library for old songs that might need attention, so that's how I came upon these. You can select all of a track by clicking on its Track Control Panel.
What's saving you is the damage isn't enough to be audible. Thanks.
Just when I thought I had come across a great idea, Wikipedia told me that I'm not the first to think about this: Several software solutions of varying results and methods exist to counteract this problem: Sony Sound Forge, iZotope Rx2, Adobe Audition, Nero Wave Editor, and a plugin in the Audacity LADSPA package come with clip restoration software. It works surprisingly well for mild clipping. The reason you must first reduce the volume is because when you run the Clip Fix plugin it tries to re-draw the wave-form where it clips. Though this is an old question, a Google search brought me here. Nope, the sound information is missing and there is no way to recover it. To learn more, see our tips on writing great answers. You need a separate video editor to put the sound back in the video. The pointer will now change to a brush (or spray can on Linux). To use Audacity's Click Removal first select the audio from which you want clicks repaired. Create a catalog of wavelet shapes, and then do affine transformations on them until you find the best match for the clipped wave and apply that. There are a number of ways you can use Audacity to remove clicks and pops from your recording. There is also an Audacity plugin called Clip Fix that uses cubic splines to attempt to restore a continuously differentiable signal. Link to Audacity docs. If there is no healthy sound before and after a clip event, there is no fix.
