lowlevel audio synthesis subsystem. modular analog synthesizer in software
: intro to subsynth (rhymes with "substance") :
what is SUBSYNTH?
stands for SUBsystem for audio SYNTHesis
modular analog synthesizer in software
low level synthesizer subsystem based on the unit generator concept.
similar in fuction and form to hardware modular analog synthesizers, except this is all done in software.
Very general. Construct arbitrary synthesis or filtering algorithms for use in realtime or offline.
scalable. For more capability, you can reconfigure or even upgrade your hardware for more power. The software stays the same.
Control. Allows complete control over audio through standard synthesis methods.
Very portable. No dependance on special (or expensive) hardware. Everyone hears the same thing regardless of location.
Extendable. OpenSource (LGPL), with a well defined framework to build on.
: motivation :
needed a base audio system in which to build higher level audio components
some examples of higher level components:
sound engines (such as ones used in)
music composition tools
scientific sonification tools
Design requirements for such components (is that the system should be)
very configurable (flexible pluggable pieces)
scalable (on PCs, workstations, supercomputers)
: realtime :
can be configured to run on single thread, or multithread systems...
why is realtime important to SUBSYNTH
software built on this API needs to be
highly interactive (and that means we need)
guarenteed delivery of signal data
scalable to handle larger configurations
multi processor task scheduling
why soft real time and not hard/firm?
needs to run on popular operating systems
Win32, IRIX, LiNUX, MacOS, etc...
: opensource :
hardware synths (such as MIDI devices) are not portable
you cannot develop sound one place and expect it to sound the same on other hardware
commercial software synths also aren't available everywhere
licensing issues can restrict developer/researcher freedom
Peer review makes the system better.
a closed system cannot recieve this attention
: documentation :
Read the current API documentation
Subsynth originated as a class project,
read the original term paper
Read the masters
done on Subsynth.
