There is a specific version of pwl for creating envelopes. This function is "env".
You can read about it here: http://www.audacity-forum.de/download/e ... yquist.htm (scroll down to the section "Envelopes").

This is not a "forum issue". Please read the "Read Me" post at the top of this page: http://audacityteam.org/forum/viewforum.php?f=32 Automatic recording levels in software are usually achieved by simply "scaling" the input signal digitally. This is the same as recordin...

Technically, one of the main differences between the standard Audacity compressor and Chris's, is that the standard Audacity compressor is built around an algorithm for a traditional dynamic compressor with a relatively slow attack time. This means that when you use it on sounds that have sharp tran...

I'm not sure exactly what you are asking, but you could edit the Audacity Project file (.aup) manually in a text editor to create or modify envelopes. The AUP file is written in XML. Here is a bit of code from a project file that shows an envelope with two control points, one at time = 9 seconds (va...

In Audacity 1.3 there is an effect called "leveller". This is a crude type of dynamic compression effect. (See "loudness war" in Wikipedia). A much more refined version is "Chris's dynamic compressor (easy to find with Google). You can also use a limiter (there's a plug-in f...

Amplitude is on a scale -1.0 to +1.0 (see vertical scale on left side of the track) In the selection tool bar at the bottom, you can set it to show the length of a selection in a variety of units, for example, "samples" or milliseconds. (Samples will be more accurate, and you can derive th...
