Are you working in 32-bit float format?
If not, could you?

Notch (50,0.7) -> Notch (100,0.7) -> Notch (150,1.4) If you're in the UK, you can probably go narrower on the notch filter because the UK mains frequency is very stable. For a notch Q of (say) 2.0 you can combine those easily: (notch2 (notch2 (notch2 s 50 2) 100 2) 150 2) or for a few more notches ...

Please note that the plug-in in the "ReplayGain" topic here: http://forum.audacityteam.org/viewtopic.php?f=42&t=63067 is not "ReplayGain". As it says in the first post of that topic: "This plug-in is an implementation of ReplayGain that calculates the Track Gain of the s...

I agree that this issue is surprisingly complex, but it's only when we get really picky about the ultra low level performance that it really matters. For 99.9% of users, leaving Audacity Quality settings at their default settings is more than adequate. If we come out of these with an easy way to exp...

I thought from an earlier post that when the only editing being done is cutting and/or pasting, that 16 bit was acceptable as a quality setting because no processing was being done and that the result would be lossless. That is strictly correct. There will be no loss in quality whatsoever up to the...

sounds like the next step is to design the right filter stack Just what I had in mind. Because there's a low-frequency component too. It's just that the high frequency component is what distinguishes them. Oh, I see. Using Audacity's multi-track abilities may come in useful here - possibly filterin...

Really?

At least we know that the 16-bit aspect is probably irrelevant. It's a shame because the newer version gives definitely better quality. If you find any more information that you think may be relevant, please let us know, but as the only way that I've been able to reproduce a crash is by flogging my ...

The effects that you need are: Equalization - reduce some of the higher frequencies (treble) - sounds tend to become more dull with distance. Stereo Delay/Echo/Reverb type effects to simulate the sound bouncing around off other objects and to "diffuse" the sound. I'm not sure what good ste...

I was rather hoping to do the filtering/processing in the plugin: the filtering to extract the signal in a way that's useful to the plugin makes it nearly impossible to analyze by eye later. We can possibly do that, but it it would help a lot if we know exactly what sort of filtering we need before...
