I just updated to v 3.0.2 from 2.2.6 or 2.0.6 )gone, so I can’t verify).
In 2015 I recorded some concert video with a modified camcorder (replaced electret mic capsule with an external XLR jack & used a percussion mic screwed in to the camera tripod socket).
Somewhere I saw a graphical editing tool for other software that allowed graphical removal of offending waveforms via the mouse.
In 2015 I couldn’t find a way to do that in Audacity and tried many methods, starting with LPF/wind filter approach, but that caused too much degradation in general (LF content loss).
What worked best (in my mind) was creating a narrow notch filter and running that as many times as necessary on each narrow time slice affected with hand-rustling sounds. It worked but took many hours…I ‘processed’ one 10 minute tune which probably took that many hours. Haven’t touched it since.
So, maybe plugins are more sophisticated several years alter or I’ll figure out another method. I am not even sure I used only Audacity. I’ll have to get back up to speed on whatever I considered my ‘method’ previously. One problem I encountered frequently was removing audio from .mov files for separate editing often reattached with a different video frame rate. I had best results where I wished to keep the video and audio together editing the audio in a video program (to avoid ‘breaking’ the audio/video interleaving/sync).
I may separately pursue removing the audio as the video wasn’t very good). This will solve the A/V sync problems and allow audio-only processing methods.
Any suggestions are appreciated.
