On the click noise, I only used the Multi Tool once and on the Thuds, I used it multiple times. My settings for the Spectogram are as follows as I think it gives a clearer picture of the areas in the wave that need repair:ġ - Filter Curve – 100 Hz Rumble – on the whole audio.Ģ - Highlight the area to fix and use Effect > Nyquist > Spectral Edit Multi Tool – you may need to use it multiple times on the same spot. Also, if you zoom in closer to the bad sections of the audio, you can get the rectangular selection area of the Spectral Edit Multi Tool to fit better into angled areas to clear them up. If you wanted to try multiple fixes on different areas, you could probably narrow it down to a better quality. But I did not spend a lot of time to get a more precise fix. The noises are reduced, definitely not completely, and the editing probably negatively impacted overall audio quality. I’ll tinker with your audio when I get a moment and see if there is anything I can come up with. You probably want to look at the 4 part Spectral Editing Mini Course by Paul Licameli – the person who worked on the Spectogram feature for Audacity. The other two are likely mixed in with audio that you want and so pulling off the noise in those cases likely will not work well. When you look at the first noise, it stands out nicely. I think that unless you are really good with Spectograms, the adjustments you need to make are going to be trial and error. A description of the De-Clicker and De-Esser Plugins are here along with links to the Plug-Ins: Relative to using the De-Esser Plugin, I think once you locate the frequency of the sounds that are a problem, you would narrow in on that frequency in the selected audio and apply the De-Esser Plugin. If there are a lot of these noises in the recording, doing it this way will definitely be tedious I can look at that later tonight when I get home and see if there is anything I can do - but like I mentioned, I’m fairly new to all this too. You would just highlight the small section of the Spectrogram that is causing the problem, instead of the full height, and use one of those tools. The other Spectral Editing Tools (under Effects) might help. The other noises are a bit more difficult as they seem to be more mixed in with vocals and they don’t cover the full spectrum of frequencies. If the preview of the audio with the cut sounds okay, then you can just press delete and that section will be removed. You can adjust the length of the “Play Cut Preview” by going to the Playback section of Preferences under the Edit menu item. Then press the “C” key which give you a preview of the audio with the selection removed ( ). Then press the “Z” key which moves the selection just slightly so that the boundaries of the selection are at a zero volume (that helps to avoid creating new clicks when editing). An easy way to remove this might just be to zoom in a bit and then carefully highlight just the section of the audio with that vertical line. I’m at work and can’t mess around with this right now, but a simple fix might be that first noise since it is clearly visible as the red vertical line. I’m at the beginner level too but like you I am willing to try what is available. Am I right? And what about the first noise? What kind of noise is it and what should I be looking for on the spectral view? Can you please explain to me step-by-step how exactly can I remove those noises either using the De-Esser plugin or the spectral editing tools? Related to that, OK I think I can identify the thud noises on the spectral view as the yellow bar that drops bellow 100 Hz frequency.
