unable to create these tones

[steve]

Congratulations on your successful modification.

A couple of suggestions that I'd make regarding the code, which I hope you will find useful:

1) For new plug-ins, it is highly recommended that they are written as "version 4" (the most recent version). See: https://wiki.audacityteam.org/wiki/Nyqu ... rs#version


2) Use spaces rather than tabs, and avoid trailing parentheses.
When I look on this page https://github.com/ElliotMebane/Isochro ... odInOut.ny I see code like this:

Code: Select all

(setq *waveform*
   (abs-env 
                (list 
                        (pwl  
                                0 -1
                                ftin 1
                                ftout 1 
                                pw -1
                                1 -1
                        )
                        (hz-to-step 1.0) t
                )
        )
) 

For anyone familiar with LISP, it becomes much easier to read like this:

Code: Select all

(setq *waveform*
  (abs-env 
    (list 
      (pwl 0 -1 ftin 1 ftout 1 pw -1 1 -1)
      (hz-to-step 1.0) t)))

3) In the above, PWL should take an odd number of arguments (http://www.cs.cmu.edu/~rbd/doc/nyquist/ ... l#index407). The final "tn" is missing.

Given that the initial time (t0) is zero, it would be better to write this with PWLV (http://www.cs.cmu.edu/~rbd/doc/nyquist/ ... l#index409)

Code: Select all

(setq *waveform*
  (abs-env 
    (list 
      (pwlv -1 ftin 1 ftout 1 pw -1 1 -1)
      (hz-to-step 1.0) t)))
