Perhaps a different pronlem. You add many one samples sounds but they have the same time extent, not disjoint.

Do you see climbing memory usage before a crash? On Windows I watch Task Manager. I have caused memory exhaustion which makes Audacity crash. But could it be crashing otherwise?

I have emailed Roger Dannenberg about this problem and he has reproduced it. It appears that addition of sounds with domains that do not overlap results in memory leaks.

I tried what I described with snd-xform, and got only slightly different numerical results without the memory leak.

More experiments done with selective commenting-out of the complicated calculation I am attempting. The surprising answer is that the culprit is innocent looking snd-add, but not just any use of it. It seems a necessary condition for the excessive memory use. What I'm doing: Use snd-fromobject to ca...

Yes, I just tried with just one minute and watched Audacity's memory usage in Task Manager climb from about 46 M to 683 M and not drop back even after the computation completed. Is the process taking more memory but not really leaking it? Does its memory footprint not change if I undo and repeat? I ...

Some of my experiments in Nyquist programming are being frustrated by seeming memory leaks. I don't have a small code example to demonstrate it, but let me describe what I'm doing. Iterate over fft frames. (Typically a 2048 window and a 32 skip.) Calculate a certain value based on successive frame p...

I meant to ask about your de-esser. I found discussion of it with a search of old forum posts but only found a broken link to another site.

Can you explain "dynamic compression." Is there any simple version of that one could code for just one sibilant sound? Then in combination with the rest of my work, who knows.

Hello, I posted an earlier experiment here and I see there were many downloads but little discussion. http://forum.audacityteam.org/viewtopic.php?f=42&t=72160 I have been working off and on at this. I am a narrator. My intention is to identify boundaries between speech segments in vocal tracks, then...
