There are two additional wave forms that can be integrated into Steve's code:
Just replace *sine-table* in the last line with either *tri-table* or *saw-table*.

I've still the impression that your procedure is unnecessarily complicated.
How do you accomplish this audio stretching?

Is it possible to expand your patch to have a curve instead of a straight line? That would be possible, but the hard part is that if you want a smooth transition between the original waveform and the new "line", you need to be able to calculate the curve. For example, if you were to use a...

Thanks for the report. It is obvious that the loop runs out of "sound". That's queer 'cos I do not get this error. It might be sufficient to replace "s" with "(cue s)". Anyways, It is fine that you can work with the quantize part alone. Another idea would be to use weig...

Yes- good point, I'll be mindful of the dither functions as I dig into this. I'm looking for the best audio that the various bit-depths can provide (rather than a strict mathematical reduction to X bit-depth), so I'll probably want dither enabled, but will check both ways. Also, the above Nyquist P...

Amplify has a 50 dB limit in each direction. You should use the Nyquist prompt for such things. For instance with this code: ;; Produce 16 versions of the original, 16 down to 1 bit. (seqrep (bit-depth 16) (quantize s (truncate (expt 2.0 (- 16 bit-depth))))) The bit-depth is gradually decreased, the...

Thanks. It worked with WASAPI and speakers, whereas with headset (USB) I got an error message when I tried to record; something like "please check recording device and sample rate settings" I think. I also got some weird skipping in the beginning whenever I recorded something, but I worke...

In my opinion, the editor should be promoted in the direction of a normal file/folder display (e.g. like in the Windows Explorer). It is essentially just a table with at least 3 columns. On opening, nothing is selected. Moving the cursor selects one label (with focus). A mouse click, ctrl-space or &...

There's a similar topic: http://forum.audacityteam.org/viewtopic.php?f=39&t=74036&p=220264&hilit=click+track#p220264 It wouldn't be that hard to allow custom tones in the click track generator (or rather a clone of it). The nice thing about generated clicks is that they do work for any s...

Why not user-defined formats, such as e.g. in Excel? You'd enter a string and the time would be displayed accordingly. There had to be some predefined characters, of course. For example: H:M:SS.CSCS (...s) where H=hours, M=minutes, S=seconds, CS=centi-seconds and s=samples One placeholder means that...

As for me, I vote for all three options with the latter as the ultimate goal.
The user should eventually be freed from any latency worries--it's all done in the back ground.
