Here is a new program that lets you design your own Audio Unit plug ins.

http://www.sonicbirth.com/

cBirth is an AudioUnit designing application. The first in its category,   it 
allows users to build their own AudioUnit plugins, either by working with   
existing circuits or by creating circuits completely from scratch. SonicBirth   
is also an AudioUnits package, as it comes bundled with a set of plugins 
designed   for standalone use as plugins as well as pre-constructed circuits to 
modify or   build upon for creating new plugins. Whether you're looking for 
traditional eqs, compressors, and reverbs, or softsynths, distortion, and filters, 
  etc., SonicBirth allows you unprecedented freedom and creativity over your 
sound.

 SonicBirth is based on a powerful, flexible engine. Every plugin can be used 
in 32 bits   or 64 bits for added precision. Since all plugins share this 
engine, any improvement in   speed will benefit all of them.

 Take a look at the  visual tour   to see how simple and powerful SonicBirth 
is.

 The prebuilt plugins 

 These are the currently available prebuilt plugins.   New ones will be added 
over time, free of charge.
     •       Multiband Scraper: Degrades the bit depth and sample rate   of 
the signal independantly over and under a user selectable   frequency.
     •       Simple Reverb: A simple reverb based on Jezar's Freeverb, with 
the   the addition of a feedback delay line and selectable filter.
     •       Multiband Freeverb: Jezar's Freeverb with a twist!
     •       MIDI Filter: A MIDI controllable, lowpass/highpass selectable 
filter.   Frequency is set by the note pressed.
     •       Bassdrum: A bassdrum synthesizer, with variable slope, punch and 
distortion.
     •       Rainy synth: A simple synth showing a filter used in an unusual 
way   to create a new sound.
     •       5 Band Eq: A five band, with variable center frequency, Q and 
gain,   completely MIDI controllable.
     •       20 Band Eq: Simply a basic twenty band eq.
     •       Width Enhancer: Stereo width enhancer/nullifier.
     •       Limiter: a seven stages, 2 ms look-ahead limiter.
     •       Compressor: Audio compression with variable attack, release, 
threshold, and knee softness.
     •       Gate: Audio gate with variable attack, release.
     •       More to come!

 Developing and sharing your own plugin   

 SonicBirth allows you to modify the prebuilt plugins and create new ones 
from scratch. For example, you might want   to take the Multiband Scraper, and 
make the frequency   controllable via a MIDI keyboard instead of an on-screen 
slider.

 You could take two circuits (elements patched together),   and mix them in 
an original way! SonicBirth allows you to   create and modify a plugin while it 
is playing, so you get   immediate results.

 Best of all, you can share the results with everyone:   of course, unless 
they buy a license, users will have to run   it in demo mode, but you are 
definitely not limited to the bundled plugins.   (If you wish, you may also submit 
your plugins for them to be bundled with the main application.)

 Try it out! 

 Hop on to our  download page   and try the demonstration version.   The only 
difference between the demo and the paid version   is that it will override 
the sound for one second every thirty seconds.   Should you like SonicBirth, 
you can easily buy a license online.

 For a limited time, SonicBirth is offered   with a 30$ rebate on the final 
price.   If you are good with graphics, check the screenshots   page for a way 
to get SonicBirth for free.
