Granular synthesis - was Future module vote - VC Phase Shifter

Granular synthesis - was Future module vote - VC Phase Shifter

1999-05-13 by Dave Bradley

David,

Have you explored granular synthesis? Briefly, it is a technique for
deconstructing sound into "grains" (small snippets), and reconstructing to
make new timbres. Samples or oscillators can be used as the sound sources.
Operations include playing grains backwards and forwards, controlling grain
size and density, etc. Kinda sounds like what you are talking about.
Somewhere out there on the net is a freeware demo granular synthesis program
for PC. I can't think of its name, but I have it at home on one of my PCs.

Do a web search on "granular synthesis" and see what info you get.

BTW, these alternate techniques such as granular and FM synthesis CAN be
practiced on modulars, given enough hardware.

Then what is the difference between wavetable and granular. I have heard
both the Microwave (wavetable) and Kyma (granular). Is wavetable just one
type of granular?

What kind of setup would you need to do granular on a modular? I can't even
begin to imagine...

Hi Dave.
can you please explain more how this techniqe can be done in modular,
what moduls needed ?

Hi David n All !

Hi Sarah,

regarding your granular synthesis programs post on music-dsp....

My Windows Shareware program AudioMulch (www.audiomulch.com) has two
real-time granular synthesis modules, one is an emulation of Curtis
Roads
"Cloud Generator" the other is loosley based on Barry Truax's work in
the
field and more strongly derivitave of my earlier "overSYTE" real-time
granulator for the macintosh (which is free and I believe accessable
via
Tom Erbe's CompMusicMac links page.) With either program you can
granulate
a soundfile or a real-time sound source.

I have been designing and performing with real-time granulators for a
few
years now... the AudioMulch granulators are flexible and allow a high
degree of control. One feature I have implemented which is not
generally
seen in granulators is the ability to quantize the grain stream to
various
subdivisions of a global pulse. The quantisation may be varied from
none
(random event distribution) to full (all grains fall exactly on the
pulse). AudioMulch 0.8b1 will be available from the web site in the
next
day or two and includes midi sync, hence quantised granulators could
be
synced with a midi sequencer or other clock source.

Best Regards,

Ross.

The first program I ever worked with was GranuLab, a shareware
program for
Windows 95/98. It can be downloaded from

http://hem.passagen.se/rasmuse/Granny.htm

A really cool looking program is Stampede II, for the SGI. It has
lots of
different modes of operation, including pitch-synchronous granular
synthesis. It can be downloaded from

http://www.kgw.tu-berlin.de/~gb/stampede.html

No Windows, Linux, or Mac versions, but there is a note on the page
to the
effect that the functionality of Stampede II will soon be available in
Native Instruments Generator program, which would be cool.

Subject: GrainWave 2.2.0 Release

I am happy to announce a new version of GrainWave for those of you
who use
Mac PPC's. Among other new features, it now has a text-based
instrument
definition language. You can check it out at:

http://www.nmol.com/users/mikeb/grainw.htm

GrainWave is a real-time software synthesis and DSP engine for
PowerMacs.
It
has an open architecture and very small output latencies (~10 ms).
It can
run underneath other MIDI applications (like MAX or a sequencer) and
receive input from them. It can also process your computer's real-
time
audio input. GrainWave does not require any specialized audio
hardware.
GrainWave has a plug-in architecture which allows users to design
their
own
DSP algorithms in C and run them with the GrainWave engine. The
easy-to-use SDK is available at the above-mentioned website. -- Mike

Csound also has some granular capability . url see up .

Hope this helps .

Cheers


Keep 'em oscillating :)
