Yes, I understand the Shannon-Nyquist theorem, folks. That's why I don't just do it with a mess of line segment ftables. :-p

There are many viable approaches. Off the top of my head, I think one
could create a pwm generator out of these ingredients:

phasor
user-defined opcode
setksmps
if then else endif

I'd be happy to elaborate. Not sure if you want the solution, or if
you want to try doing it yourself. The latter is more fun. :)

Re: Re: Re: creating a variable width pulse wave...

2009-11-09T18:17:07Z

It's not that easy to get right, and that's why there is an opcode. There are several ways.

You can have a set of wavetables, each of which contains a bandlimited sum of harmonics, i.e. you assign a base frequency to each table, then add partials to it only until you approach the Nyquist frequency. This works very well if you use enough tables, and go almost up to Nyquist with your partials. But it only works for static waveforms.

You can use a bandlimited interpolation (BLIP) technique, where you shift, scale, and sum copies of a sinc signal to reconstruct a desired waveform in a bandlimited manner. https://ccrma.stanford.edu/~jos/resample/Theory_Ideal_Bandlimited_Interpolation.html has the math with a good illustration.

You can generate a bandlimited impulse train (BLIT) and integrate it with a filter.

A more comprehensive summary is in https://ccrma.stanford.edu/~stilti/papers/blit.pdf.

You can oversample a wavetable, and then low-pass filter.

There are variations on these themes, as well.

Hope this helps,

Mike

designing an instrument that generates pulses of variable width might
require some coding, but is somewhat trivial [1]. but that's not the
problem. the problem is that what you really want is a band-limited
approximation to the pulse wave (assuming that you want an audio
signal). and that is definitely NOT a trivial task. (vco is almost there
but not quite, vco2 is much better.)

please excuse me if you're already aware of the problem, but in case
you're not, there are several papers discussing the problem of
band-limited digital synthesis of classical analog synthesizer
waveforms, like for example:

'Modeling Analog Synthesis with DSPs' by Lane, Hoory, Martínez and
Wang, Computer Music Journal Winter 1997.

'Alias-Free Digital Synthesis of Classic Analog Waveforms' by Tim
Stilson and Julius Smith, available on-line.

'Band-Limited Simulation of Analog Synthesizer Modules by Additive
Synthesis', by Amar Chaudhary, AES

again, please excuse me if you already know all this.

Normalizing floating point .wav files

2009-11-09T17:10:27Z

I've just realized that I must work in floating point. I have this idea of
systems of soundfile makers that produce a hierarchy of mixable
files that will yield the end result. I can't be expected to keep tweaking
master volume variables as the composition changes in order to keep
the integer files near their maximum amplitude.

I know that such a utility used to ship with csound. Was it 'sndnorm' or
something like that? I'm on Kubuntu right now, and I installed csound-utils,
but I don't get anything good that starts with 'snd'.

I just want to go:

some_prog myfloatfile.wav > my_nice_normalized_16_bit.wav

and have the new file be normalized to zero dB in it's native bit width.

Re: Re: Makefile strangeness [OT]

2009-11-09T16:49:26Z

As it turns out, GNU Make has an idea of 'intermediate' files. Make
realized that .sco files only exist if the .py score generators make them.
If the intermediate file does not exist when Make is run, then it keeps things
that way, and automatically removes them after their use. This might have
made sense 20 years ago, when disk space actually mattered. As it is, the
behavior is flawed in my opinion. In my Makefile, touching an orchestra
means rebuilding the .wav file, which invokes the score generation program
only because Make has so helpfully removed my .sco file. Lame.

I found out that adding the line:

.PRECIOUS: %.sco

solves the problem.

Sorry for not having googled extensively before asking the question.

Thanks,

Tobiah

Ahh.
I see, or I'm only a few steps away from seeing when I have a little less on my plate.
I had a "duh" moment making oscillators with .wav files a week or so ago (actually, my sample-based oscillator is a very simple expansion of the phasor/table oscillator I learned from EAST ;-) and I was wondering if there was some similarly obvious thing I was missing.
Apparently not.

I don't see an rm command in your Makefile, which seems odd.

Have you tried running with make -d ?

That should tell you exactly what is happening,

Or is it something to do with --keep-sorted-score??

then you'll know the outcome of the test

One reason could be, that the script includes a Qt Version which is not

install Qt from the Qt website.
I also made some changes, that the build is for Intel and PPC (called
Universal Binary) maybe this works? So I uploaded 3 different versions,
it would be great if you could test all 3?

1. this is the pure build, before a script includes anything, which
could be intel..But Qt should be installed on your mac to run it.
http://www.ketchupok.de/qutecsound_build/qutecsound_pure_uni.zip

2. This is the a version, without Qt, but packed with the
script..(probably exactly the same as above :-)

3. This one includes Qt, but is a universal now, maybe this works?

If non of them is running, we need you to make the builds!

Makefile strangeness [OT]

2009-11-09T10:01:11Z

This makefile works as expected, but it always
automatically executes an:

rm some.sco

for each score file made. Does anyone know why Make would
do that?

What's strange is that it doesn't really hurt the build process.
I never touch the .sco files directly, although touching the
orchestra does cause the score to be generated again, which
for very large scores can be time consuming in itself.

Thanks,

Tobiah

When I google 'csound list', I get to this page from the first hit:

http://www.csounds.com/list/index.html

The list links on that page are still broken.

I've been posting builds and getting feedback from the blueusers
mailing list. It's very close now and the users have been very
helpful in giving feedback on found bugs. Most of the remaining
issues are minor cosmetic issues, with one major feature to
reintroduce (the score navigator). Other than that, I just have to
update the documentation (which may take a little time). I'm giving
myself a deadline of Dec 1st for the latest which I'll release, and
hopefully will have it out before then.

Problem mailing to list

2009-11-09T08:36:06Z

I had to rebuild my machine, and after that started to send messages
to the csound list. I kept getting the error "Relay access denied. Please
check the message recipients and try again". I figured that I had configured
my SMTP installation badly, so I subscribed from my gmail address. I get the
same error, using Thunderbird configured for gmail IMAP. I can however
(as I'm doing now) send from the gmail web interface.

Can anyone tell me what I might be doing wrong?

Thanks,

Toby

Bug in pan2

2009-11-09T00:47:33Z

I found a small bug in pan2 while studying the different stereo modes. imode
= 3 does not make much sense:

Line 86 reads "cc = SIN(PI*kangl*FL(0.5));" It should probably be "ss = ..."
instead.

If there is a more appropriate place for bug reports, then please let me
know.

Re: New Beta Posted

2009-11-08T19:52:38Z

Hi Algodo,

Thanks for notifying about this! I think I have it fixed up. I put
up a new build that should fix up issues with JMask's interface, has a
couple of small fixes, and now has the manual (it's the old manual for
0.125.0 but I got the build working for the HTML and PDF and have it
automated as part of the zip build now).

http://www.kunstmusik.com/blue_2.0.0_beta.zip

Thanks!

It already attracted my attention, but i haven't tried it yet. I'll follow
your advice then and dig it.

Well, elisp seems to be pretty straight forward to me (on my stage of
noobism :). At least it is definitely achieveable.

have a look at the code around line 90 in csound-csd.el
that's where the environment variable handling via custom is
implemented. beware of the big macros :) cscsd-defenv does most of the job.

this thing is rather complex, also because csound-x is a component of a
larger system, called Surmulot, where csound is packaged as another
component. in Surmulot, the user can swap on-the-fly from the packaged
csound to its own system-wide csound, if any. so csound-x provides all
the logic needed to reconfigure the whole environment of the Emacs
process dynamically.

if you're brave enough to go and dig in the code, then good luck !

best,

Stef
