Making it into a sequence: (defun tone (hz dur) (stretch-abs dur (mult 0.4 (pwlv 0 0.01 1 0.2 0.4 0.8 0.3 1.0 0) (lp (sim (osc-pulse (pwlv hz 0.4 hz 0.5 (/ hz 2.0) 1 (/ hz 2.0)) (mult 0.4 (sum 1 (hzosc 1)))) (osc-pulse (pwlv (* 1.01 hz) 0.4 (* 1.01 hz) 0.5 (/ (* 1.01 hz) 2.0) 1 (/ (* 1.01 hz) 2.0)) ...

The Hard Limit setting doesn't affect anything that doesn't peak.

That sounds rather similar to the "Hard Limit" setting in Audacity's Limiter effect: http://manual.audacityteam.org/o/man/limiter.html

Just for fun: (setf hz1 440) (setf hz2 220) (stretch-abs 3.0 (mult 0.2 (pwlv 0 0.01 1 0.2 0.4 0.8 0.3 1.0 0) (lp (sim (osc-pulse (pwlv hz1 0.4 hz1 0.5 hz2 1 hz2) (mult 0.4 (sum 1 (hzosc 1)))) (osc-pulse (pwlv (* 1.01 hz1) 0.4 (* 1.01 hz1) 0.5 (* 1.01 hz2) 1 (* 1.01 hz2)) (mult 0.4 (sum 1 (hzosc 2.3)...

You asked for examples: please hear attached 3 different versions of a scraped audio file which contains a good bit of background noise (I think it's wind). The 1st 7 seconds is the Raw file; the 2nd is same file with Noise Reduction; the 3rd is with Noise Removal. Thanks for the samples. I think t...

Check that "Sound Activated Recording" is not enabled (near the bottom of the Transport menu).

If that's not it, please tell us what you are trying to record and what settings you have in the device toolbar.

Plot Spectrum: http://manual.audacityteam.org/o/man/plot_spectrum.html

For one thing, tone generation always starts with zero The built-in "Generate > Tone" effect always starts the tone at "zero phase", but with Nyquist you don't have that limitation. For the basic "OSC" oscillator, the full syntax is: (osc pitch [duration table phase]) ...

There is some explanation of high / low pass filters in the manual: http://manual.audacityteam.org/o/man/high_pass_filter.html http://manual.audacityteam.org/o/man/low_pass_filter.html These two effects are written using Nyquist. If you look in the Audacity plug-ins folder you will find "highpa...

Have you checked if <algorithm> is included in the places where this occurs?
