Any suggestions?
If you quote me, please put your comments first.
I have already listened to my questions.
Thanks.

Dear Csound,
I too would love to see both SoundHack's "Spectral Extraction" and "PVOC
Resynthesis Gating" functions added as opcodes to Csound. I use them all
the time in my DSP classes at Berklee. They would be a great addition to
the Csound family. And they could fit nicely into the suite of pvoc
extensions added by Richard Karpen.
Maybe we could encourage Tom Erbe to share his code and our resident Csound
Vocoder guru Richard Karpen to add them?

The TOM server, at tom.cs.cmu.edu, does a good job on TeX and HTML and
should have no trouble with RTF. It's impressively tolerable at
converting PostScript, considering that's really an impossible task.
I've never tried it on PDF.

Hi all,
a new version of Win95 realtime Csound is now available at my site. It
covers 3.482 bath version and can optionally enable Win32 DirectSound
APIs. Csound now can write samples directly to the hardware primary
buffer. This reduces drastically latency delay on all sr frequencies.
Obviously DirectSound 3 or later must be installed on your computer and
your audio card must be certified for DirectX from Micro$oft.
The url is:
http://www.geocities.com/SiliconValley/Way/7041/download.htm
VMCI (Virtual Midi Control Interface) is a freeware GUI program which
allows the user to send
most MIDI data to a MIDI device by means of gestural actions on the
computer keyboard and
mouse. VMCI is fully configurable and can give the user a total control
of MIDI messages, even
without any MIDI interface card and any external MIDI keyboard or
controller. This program is
primarily thinked to be used to control real-time versions of Csound,
but it can also be used with
any internal or external midi device or computer programs such as
sequencers.

Happy csounding

To produce the first quarter of a sine wave the easy way, use GEN09 like this:
f1 0 1024 9 .25 1
This produces one full strength partial at one-quarter of the "fundamental" frequency. As I understand it, GEN09 only stores one period of the waveform. Since this partial's period
is four times that of the fundamental, only the first quarter of it will fit into the stored table. Anyway, whether or not I got the technical stuff right, you can verify
graphically that it works when you compile your orc/sco.

sorry, I did not mean to be harsh: the point is that sockets mean
setting up services, client-server communication etc. etc. I know how
to do that and I am ready to help if there is a real need, but this
does not seem to be the case. Really, bi-directional (named) pipes or IPC
communication should be more than enough (in fact, we are discussing
uni-directional ones right now...).
Now, speaking of 'csound -L stdin',

did *NOT* work for me at all as of 3.482. I investigated a bit in the sources
and found out:
1) indeed, "stdin" as a name is taken into consideration and opens and
read _io_[0] (stdin, that is)
2) there is a commented out 'if' statement at musmon.c line 183 that
blocks out the reading from stdin. There is no comment about why it
is commented out (but read further).
3) removing the comments 'csound -L stdin' *somewhat works*. The behaviour
is actually fairly funny. This works:
echo -e "f1 0 4096 10 1\ni1 0 10" |\
csound -b8192 -L stdin -do devaudio oscil.orc
although csound does'nt stop after the 10 seconds, it needs a Ctrl-C;
but this does not!
cat oscil.sco |\
csound -b8192 -L stdin -do devaudio oscil.orc
(of course, oscil.sco was made out of 'echo -e ... > oscil.sco', so the
stuff piped to csound is identical) - further enquiry and debugging showed
that csound is actually blocking at the *output* writing, not in the input;
The problems are:
a) I don't see how a unix application (in this case csound) knows what
is coming on the other side of the pipe (why 'echo' works and 'cat'
does not; btw, also 'csound -L stdin etc. etc. < oscil.sco' does not
work)
b) what has the output to do with the different inputs
now this completely surpasses my unix chops and my intellectual
capabilities, so I gave up and went back to study fcntl() and all its
implications. That's enough for me...
4) on the positive side of things, I tried something else:
mkfifo /tmp/fifo; # so I don't forget to mention
cat oscil.sco >> /tmp/fifo & csound -do devaudio oscil.orc /tmp/fifo
this works no matter what you use to fill /tmp/fifo; no '-L stdin' etc.
involved - ideed named pipes work very well under linux ;-)

yes of course. Btw, somebody else suggested to zero out the kernel buffers.
That means to do an ioctl() call for every character, is'nt it? That'll
cost some time...
Thanks Paul for pushing us all to investigate... As far as I can see
the problem is far from solved.

I would love to have spectral extraction and gating in Csound. I'll try
to
get my code into an intelligible form and send it on to Richard K
(Richard,
I'm assuming you are interested in working on this?)

This util was ritten in VB, which will not run under linux.
Can anyone on the list suggest a way to port it to linux?
If you quote me, please put your comments first.
I have already listened to my questions.
Thanks.
