(First, please let me know if it's better to privately email the
authors, instead of reporting problems/questions to this list)
I'm attempting to use the "scaled-to" option in CLM "with-snd", by way
of the Stella "open" command. I've run into two problems.
First, something gets screwed up with the file format when I specify the
scaled-to option, as you can see from the attached trace. (It works fine
if I don't specify scaled-to).
Second, (And this might not be related to scaled-to), If I then perform
a new Stella "open" command, this time not using scaled-to, I get the
same problem, as if the scaled-to option is still in effect. This is
shown in the latter part of the attached trace.
Relavent customizations that I use (on Linux/ACL) are these:
(setf default-sound-file-type RIFF-sound-file)
(setq default-sound-file-data-format snd-16-linear-little-endian)
... and here is the trace:

*** ADDED NOTE: Problem #2, re-opened test.snd without "scaled-to",
still gives the same result! ***
