Ah, thank you.

Perhaps something like "refresh audio devices list" might be a bit more self explanatory.

Windows 7, Audacity 2.0.3.

Recording with a Blue Snowball.

It's too easy to knock the USB cable out of the back of the mic. If this happens during a session, and I reconnect and try to record again, I only get a flatline. I must exit and restart the program.

It's irritating but not debilitating.

More info: I modified my example again (the one with varying silence-dur and multiplier), reversing steps so that the scaling by multiplier is applied first and snd-xform after. Still the problem is seen with multiplier of 1 but not with multiplier of -1. Thus the scaling (by -1) of the snd-xform of...

I'd say an evaluated behavior is a sound, but a function that evaluates a behavioral expressions and returns a sound, is still a behavior. A function can be a lisp value. So perhaps I am incorrect to say a "behavior" is never a value. The closure that Lisp constructs still keeps its sensitivity to e...

I reproduced Roger's example, but just returning (test) and looking at Audacity's waveform display. I see the difference between his and Steve's modification. Steve gets the anomaly to reproduce. Roger didn't. I am trying to understand the sound/behavior distinction that Steve urges me to, but I thi...

I am trying to understand Nyquist. This is a summary of my understanding. This is what I wish I could have read two months ago when I started experimenting. There are non-Lisp functions callable from Lisp that have snd- in their names, and they implement certain operations on sound sample data effic...

I also tried swapping the two summands in the last example. This seems to have no effect. Maybe I shouldn't speculate more, but here it goes anyway: When a sound object generates samples on demand, it does so in "batches" or buffers, and only after generating a buffer full, a compound sound like the...

Here is an adaptation of Steve's example that just prints some numbers to debug output of Audacity's Nyquist Prompt. I don't use s and I don't judge by the modification of tracks in Audacity. I think any misbehavior I see is all Nyquist and not a Nyquist-Audacity interface problem. Note that: snd-le...

I am unfamiliar with s-plot. Will it expose the problem? The "problem" is readily seen in Audacity. Also, as mentioned, (s-rest (get-duration 1)) really should have been (s-rest 1) but that's less important.

I use Audacity 2.0.3 on Windows 7.

To be very explicit, here is a complete example of "misbehavior"for me. It assumes s is bound to some sound, it need not be a 100 Hz wave, the chirp that Steve used will do. (Incidentally I changed (s-rest (get-duration 1)) to (s-rest 1) which is more correct to leave the length of selection unchang...
