Audacity Forum

I have posted a few bug fixes in a new version. See top of thread.

How in xlisp can I get current clock time so I can print it?

Or otherwise figure out where time is going in my code?

So drop outs are not natural but undesirable parts of the really recorded sound but rather failings of the media. Whereas the clicks I try to filter out are distracting things my misbehaving mouth really did. I don't look at the wiki enough. Where do I learn to edit wiki? I saw a wiki page for the f...

I followed up the suggestion to use iterations of eq-band in my experiments today. Just constant gains on each interval, and a crossfading envelope. Mostly very pleasant results, and speed is not bad. May next try (1) broadening the fix interval a bit to each side of the identified click, (2) using ...

Thanks for the help, but please let's keep this thread a discussion of the tool, not the Lisp language. I don't mind if you delete some of the previous off topic posts once my fixes are successful. Here's a question: what do you call it when a frequency component makes a sharp drop, and then a rise,...

As for those update macros, I wrote them to avoid repeated evaluation of val, and to evaluate x only once as a value and once as the setf target (I think that's "place form" in Lisp jargon). You don't actually need to go so complicated. This version is marginally quicker: (defmacro update-max (x va...

I have found my silly mistake in the implementation of the absolute threshold test. I also found that my changes to make the progress indicator smoother were not quite right. Expect a version 2 file with minor updates. If you are impatient for the fix, replace the appropriate cond branch with this. ...

I have identified a marginal detection case and I am puzzling over it. I may come up with something.

I am aware of the instability of detection of some clicks, as the starting time of the selection changes. I am not yet sure of the explanation. I suspect that some clicks are not symmetrical, having sharp attack and then decay, and that has something to do with it. I have not seen crashes. As for th...

UPDATE 5 Nov 2013: New version labels some clicks that escaped detection in the previous. Also smoother progress indicator. This goes under the Analyze menu. It labels brief bright spots and vertical streaks in the spectrogram, which do not necessarily go up to high frequencies, but might also be lo...
