Like many things in life, this requires patience, time, and thought, but
the value (and fun) is the journey, not the destination.
The best sound analysis tools ever invented are the human ears and the
brain they are attached to. Concsiously, listen to sounds around you:
birds, cars, washing machines, brooks, people, even ..... musical
instruments. Why do they sound the way they do? Pick one aspect of a
sound, pitch, timbre (waveform),envelope, rhythm, etc. Try to recreate
it with the tools at your disposal knowing what you do about how they
work. Csound is probably the best, but not necessarily instant
gratification. Example: birdsong are great pitch studies. Try to
recreate one with only a sine wave. Taking something apart and putting
it back together is one of the best ways to learn. People have done it
for millenia.
Look at other people's orc and sco files. Compile them, try to relate
the code to what your hear. Simple ones are best. This apply's also to
Steven LeBeau's question re GEN Ftables. A good source is John Gather's
Amsterdam Catalogue. Find it here:

The best qualitative sound analysis tools ever invented are the human
ears and the
brain they are attached to. Concsiously, listen to sounds around you:
birds, cars, washing machines, brooks, people, even ..... musical
instruments. Why do they sound the way they do? Pick one aspect of a
sound, pitch, timbre (waveform),envelope, rhythm, etc. Try to quantify
it an re-create
it with the tools at your disposal, using your knowledge of how they
work. Csound is probably the best, but not necessarily instant
gratification.
Example: Birdsongs are good pitch studies. Try to
recreate one with only a sine wave. Taking something apart and putting
it back together is one of the best ways to learn. People have done it

Hello all,
I have just received this message and spread it because it seems important:
If you receive an e-mail titled "join the crew", don't open and delete!
It contains a new virus who destroys the files in Hard Drive.
If you receive an e-mail titled "penpal greetings", don't open and delete!
It contains a new virus which corrupt the boot sector and send itself
to the address contained in your mail box. This virus in theory can
damage all the web.
I don't know if the mailing-list is already protected from such viruses, and
neither if the message is true, in any case I decided to warn.

1. Do you live in a cave? This is a hoax.
2. Don't post virus warnings to the csound list. That's what
virus lists and newsgroups are for.
3. Get a clue.

Arghh! Not again! This is complete nonsense. No virus can be activated
by opening an e-mail. The warning itself is the virus, and the only harm
it does is wasting bandwidth.

not at all, inside Csound. What you can do is to use the utility
program het_expo.exe to export the numbers in the analysis file
as text, then import that text eg into a spreadsheet and transform
them there. Then save as text and convert back to hetro digital
format with het_impo.exe. Or check the hetro file format in the
manual and write your own processing utility in the programming
language of your choice ;}

Now i've found that the problem is that the rescaling of signals in the
outs operator:
outs a2*0.1, a3*0.1
^ ^
does not work, and the signal outputs at full amplitude, even if you
multiply it by 0, while in the previous version of csound the signal was
rescaled as expected.
I don't think it's reson's fault, because if you (in the mills PPC version)
choose the "32-bit float -> 16-bits int" option for the output soundfile
format, you get the undistorted exponetially decaying sinusoids, because of
the larger dynamic allowed by 32 bit, wich prevents clipping.
I havent tested the * operator in other situations, though.
BTW is there a "mod" operator hidden somewhere?
