I thought Winsound has been running slowly lately.  I just ran the bach.orc
bach.sco benchmark on a 300 MHz PII.

Winsound 3.511   = 178 seconds
Directsound 2.11 = 5.82 seconds

Hmmm, something mighty fishy going on here...

Hi all,


I'm using sndinfo on various sound files that i have downloaded from the web.
they have all been converted to 44k 16 bit stereo AIFF with SOX before sndinfo
looks at them. with certain files, it outputs the following error (this is in
Linux):


'Floating point exception (core dumped)'


does this mean the soundfile is bad or is it something that sndinfo cannot read
(it just looks at the file header, right?). Thanks in advance


Peter Traub

I posted something about this earlier but am not sure it got through 
to the list properly.  I have been having a problem with filter 
clicks where the filter cutoff-freq is made to track the pitch of 
the note.  This has been a problem particularly in legato 
passages.  Here is some sample code which illustrates what I 
mean: it plays 2 legato scales.  The first is passed through a 
filter (notice the clicks at the beginning of most of the notes).
The second bypasses the filter  and does not click.  
I wondered whether anyone out there has run into this 
problem and could help me figure out a solution.

Thanks to all.

I'll take a WAG at this one.  I notice the same effect in Cool Edit Pro 1.1
when I select adjacent areas (to the sample!) of a sound and filter them
differently.  Apparently the filter algorithm (any of them, so far as I can
see from the math behind them) doesn't guarantee to leave the endpoints
fixed, or zero, or any known value.  So you get discontinuities at the
boundaries of the area the filter's being applied to, which, obviously, you
hear as clicks.  Anyway, while that may not be exactly what's causing your
particular problem, it's a problem inherent in digital filters.  I've only
ever coded FFT-based filters, but I'm somewhat familiar with the theory
behind IIR's and FIR's.  Maybe someone else has a different take on this.
If it's what I think it is, you might try to modify your instrument to do a
forced zero or fast crossfade on every note.  Off the top of my head, I
don't know if there's a way to make CSound's filters do that for you, but it
wouldn't be hard to tack on top.

On a totally different note, can anyone tell me how to desubscribe from the
list?  I've lost the instructions I had, and it doesn't appear to behave
like other listproc-style lists I've seen.  Maybe I just don't remember the
correct server name.  Anyway, I'm relocating, and until I have a new ISP,
I'll have to forgo the list.

Oh, yeah.  Goodbye to the guys up at the U of U Music Department, those of
you who still remember me .

Indeed, to get a true legato, you need to use the negative p3 system,
and connect both amp and freq (oscillator and filter)  with ramps. In
your orch all the amps are the same, so that potential problem is not
evident. Any instantaneous change of freq will cause a glitch, even with
even amplitude.
