Which parameters change in the plug-ins Subliminal.ny for example, to have a signal between 14500 Hz and 20000 Hz?

Sorry, I don't understand your question.

Thanks rin67630.
Have these curves been calculated, or taken from a graph?
Both curves look rather too flat compared with: http://en.wikipedia.org/wiki/Weighting_filter

Eq curves may be added or saved by importing / exporting using the "Manage Curves" feature (see: http://manual.audacityteam.org/o/man/equalization.html#manage) The curves are stored in XML format and so it is also possible to manually create or edit curves by editing the XML file in a plai...

I can see that it doesn't work perfectly, but it does work partially. Sorry but I think that is an overly optimistic assessment. Taking another example: I have a 440 Hz sine wave in the left channel and a 700 Hz tone in the right channel. There is no audio common to both left and right channels. fi...

Here is the procedure: 1) Make 4 copies of the waveform (these will become L+, R+, L- and R-) 2) Invert 3 and 4 3) Select all 4 > Nyquist Prompt "(s-max s 0)" 4) Split all 4 from stereo to mono 5) Of the 8 mono tracks, select 2, 3, 6 and 7, and invert 6) Mix and render each pair, to get 4...

Audacity has "label tracks": http://manual.audacityteam.org/o/man/label_tracks.html

By the way, Steve, does my plug-in now run faster with the increased speed on Linux? On my machine it runs at roughly the same speed as "Sliding Time Scale / Pitch Shift". I've got a lot of other stuff running at the moment (I'm in the middle of building the latest source code) but proces...

Should we have a "Allow Aliasing" control instead of doubling the wave-forms? That makes sense. Do you think that it is worth having a Preview button on a simple waveform generator? I'm thinking perhaps not as it is not an effect that users are going to be able to "tweak", thoug...

It makes no sense to have a alias-free square wave but no alternative to saw-tooth. Perhaps we should ship the Nyquist tone generator instead of the current built in Tone generator. For the non-alias versions, the Nyquist effect is much faster than the built-in effect, particularly for low frequenc...

Unfortunately I think not.
I have replied in the other thread: http://forum.audacityteam.org/viewtopic ... 14#p257114
