Go ahead and post a sample.

That is indeed curious, and I suspect the problem is not where it appears to be. It's probably too late to get an exact, detailed list of events leading up to the problem, so some detective work is needed. What sort of sound card are you using? Do you have any other audio devices other than that sou...

Right now I do have some semi-effective EQ settings: just a high-shelf filter That's easy in Nyquist, just use a high-pass filter. For a fairly steep filter (8th order, 48 dB per octave) (highpass8 <sound> <frequency>) for example, to high-pass the selected audio above 2 kHz (highpass8 s 2000) For ...

Can't you just turn up the volume on the player?

All forms of Noise Removal need to be able to detect a definable difference between "what is noise" and "what is the sound to keep". Some "identifiers" make separation easier than others, for example, "noise on the left, sound to keep on the right" is very eas...

Edit3: Signal Finder generated some 23,000 labels. Hmm, may have to work on the false positive thing a little bit. You're lucky. When I was working on an "advanced sound finder" effect I accidentally generated about 10 times that number :D Is there a predictable minimum gap between "...

I know nothing about Macs, but I'm on Linux, so good to know that if I refer to the command line you'll know what I'm talking about ;) If your sound card is reasonably good (accurate) you should be able to go pretty tight with the notch filter, which may help to clean up your low frequency display (...

if mdubin wants to test, I can make a build that has the quality improvements but goes back to memcpy. That would be a very useful test. As far as I'm aware those are the only two commits (changes) to the effect between 2.0.0 and 2.0.1 so if we could narrow it down to one or the other that would be...

When playing with loops and stepping through sounds, make sure that you know how to crash Audacity in case it gets stuck in a loop. In Windows you can use the Task Manager to force quit Audacity. What operating system are you using?

For single labels, use "Silence Finder".
It is not really very well named - what it actually does is to detect sounds, then place the label before the sound.

If speed of processing is not important we can make it sample accurate so that it will mark the exact start of a sound.
