Generates the following types of wave:
  • Sine
  • Square
  • Triangle
  • Sawtooth
  • Inverse sawtooth

This is slower than the standard Sine, Square and Sawtooth tone generators, but this plug-in produces tones without aliasing distortion.
The standard Tone generator can produce no-alias square waves, but it is very slow, particularly for lower frequencies.

Highlights:
  • All generated tones have extremely low aliasing distortion.
  • Much faster than the built-in no-alias square generator at low frequencies.
  • The starting phase of the waveform is adjustable
  • When applied to multiple tracks, all tracks have the same phase (regardless of frequency and duration)
  • Square wave is more square at low frequencies than the standard no-alias version.
  • Optimised for best waveform shape, frequency content and speed.
  • Works with Audacity 1.3.4 or later (1.3.12 or later recommended)
  • Very low memory usage on Audacity 1.3.13.

Install in the usual way.
Comments, feedback and bug reports welcome as always.

Here's a new version.
There are no changes to the code - the only difference is in the layout of the code.

It was brought to my attention that in some text editors the line spacing could be messed up because I used "Tab" to indent rather than spaces. If the editor is set to a large tab size (for example 8 spaces is very common) then some of the lines would be indented by an excessive amount. In this version I've changed the "tabs" to "spaces" so the layout should be the same on all text editors.

I've also made a couple of other minor changes to the layout to comply with the recommendations here: Indenting Common Lisp

Steve,

The link in your last post appears to be dead.

I googled it and found it here.
