I would guess that rights for use of an orchestra and score reside with the
author so you might want to ask them for their permission if you want to use
their sounds on a sample CD.

This is from the news file at http://www.op.net/~pbd/quasimodo/. I've
been away a lot, and busy, and miserable, and divorced. But I'm back,
my daughter Hannah is back in school, and I'm programming like a

--p
September 16th
Its been a long summer.
Well, I'm back from a summer of travelling and getting a
divorce. Its time to get started again, and as a start, several
major new items:
+ the UI is now not even linked at compile time - Quasimodo
dynamically loads the libraries you specify in the config
file, and then looks for a function called "ui_init" within
them to create the user interface. Switch UI's at run time
from GTK+ to GNU readline (command line) and even (at some
point) to Stephane's Python interface for Quasimodo!
+ new internal API to allow patching to be carried out from
such things as a command line UI
+ XML in use for preset files; support for XML module
definitions is almost complete, thanks to Stephane. We now
use gnome-xml, instead of expat.
+ Quasimodo is itself now a library! Quasimodo the program is
very simple, something roughly like this:
main (int argc, char *argv[])
{
Quasimodo q (&argc, argv);
if (q.ok())
q.start ();
}
This new structure will now allow Quasimodo to be used as an
audio engine from other programs, using the new API when
necessary to load/unload modules, set up patches and control
parameters.
+ Basic support for machines with > 2 processors is now in
place. You will soon be able to run each "cabinet" on its own
processor. If anyone has the cash for a 4-CPU Xeon machine,
it would be a nice contender for the Pulsar, except that the
Pulsar costs less than the motherboard+1 Xeon!
Work to be done in the immediate future include some
considerable effort on the appearance of the UI, making the
modules more interesting and useful, and getting input to work
smoothly and efficiently. None of these are trivial. But expect
lots of work on this stuff, soon!.

Hello list! =)
A long time ago I believe I asked some questions about how to convert floats
to 16-bit or less. As I don't remember the answers, I ask again:
What's the best algorithm to use for converting a normalized sample to
integers and get the best soundquality?
There are atleast 2 questions that comes up:
1. What method should I use when rounding? ceil(), floor(), or normal
rounding?
2. Should I add 1-bit noise to the sample? If so, when should I do this?
Should the noise be between -1 and 1, or 0 and 1, or -1 and 0?
Before, I have done something like this: (for 8-bits)
integer = floor( 127.99999*sample )
This will give me a full range output, but may give a -0.5 DC..
Thanx!

Well, some sort of comment is pertinent - we have a graphic front-end
for a public-domain Csound engine the copyright and licensing of which
traces back ultimately to Barry Vercoe and MIT, via Gabriel Maldonado in
this case. The 'pro' version of the graphic front end in question is
presented as a commercial product ("It will not be free(sorry)").
There is also the admonition:
"
It is a free software. However, You can not make a SAMPLE CD, or SAMPLE
CD-ROM with this compiled sound. It is prohibited. You have to discuss
to sound designer who makes a original Csound orchestra file such as Dr.
Richard Boulanger and me.
"
I have not come across this particular restriction with Csound before. A
Sample CD is not something I have any interest in making, but I can
imagine there are plenty that might want to do such a thing.
So is what is offered here OK in terms of the Csound license?

Hi,
One other thing that confused me when I first started working with the
granular opcodes is that the frequency you ask for is the number of times
the entire table is cycled per second. If you have a sample of a sound at a
certain frequency you need to do some calculations if you want your
granulized sample tuned to a certain pitch.
For example suppose you have a sample of a 400 Hz pitched sound that lasts 2
seconds and has a sample rate of 44100 Hz and is monophonic. This means it
has 88200 samples. The smallest power of 2 that will hold this many samples
is 2^17=131072. The number of seconds in this many samples at a 44100
sample rate is about 2.97215 seconds. In order for the sound to play at 400
Hz you would need to use a frequency of 1/2.97215=.336456
When I first started working with the granular opcodes I think I tried
things like 400 Hz, 1 Hz and .5 Hz before I figured it out.
A formula for this would be something like:
TableSize = 2^(int(logbase2(SampleDuration*SampleSR))+1)
OutputFrequency = (DesiredFrequency/SampleFrequency)/(TableSize/OrcSR)
Which I think will work except for when the size of the sample is exactly
equal to a power of two. Then don't add one.
Now wasn't that confusing? Or am I just confused?
Bye,
Hans Mikelson
