The trouble with TV is that people see some guy in a film say "computer... enhance" and magically the voice that was hidden by all of the noise is suddenly revealed in crystal clarity. The important word here is "magically". Physics does not work like that. If you have a recordin...

Get a faster computer? You've not said what format the files are in, but assuming 128 kbps MP3, you are wanting to decode around 840 MB of data to around 8.5 GB uncompressed. [update: my mistake - you did say "raw data" - but what is that? PCM? Mono/Stereo? Sample rate? Bit depth? Whatever...

10 years - doesn't time fly while you're having fun but yes in this context I prefer "peak".

You are absolutely correct - but why bother moving / copying everything to the same track? Audacity has multi-track capability, so why not use it?

I would still rather give people a bit more help here, given Windows and Mac hide extensions by default. How about .... Yes I can go for that, but it's an extra line and we're already up to the 25 line limit for 800 x 600, so we'll need to lose a line somewhere - perhaps the blank line between: loa...

Its maybe worth mentioning that you don't have to analyse the whole sound, 1100 samples should be enough. The function snd-maxsamp should probably be replaced with the function peak as the Nyquist manual states that snd-maxsamp "will probably be removed in a future version (http://www.cs.cmu.e...

Yes, for low frequencies it would be very useful. What sort of sounds are you thinking of? The most common is probably "mains hum" (50 or 60 Hz) which is unlikely to be visible at all in linear view. An alias is not a sub-harmonic Yes and no - it is "below" the harmonics, hence &...

You're asking a video editing question. Audacity does not edit video, only audio. Most video editors will allow you to insert, delete and move the audio track. Consult your video editing software manual for details.

Very nice. Thanks for sharing. To make it more easily readable for the rest of us, I've reformatted your code with indentation (below). ;;; mix to mono if stereo (defun mono (sig) (if (arrayp sig) (sim (aref sig 0) (aref sig 1)) sig)) ;;; test against powers of 2 (defun bit-test (sig bits) (snd-maxs...
