Digital Audio Processor
=======================

For Silicon Graphics (IRIX 5.3)

(c) Richard Kent 1996

Introduction
------------

Welcome to the digital audio processor for the Silicon Graphics range of
computers running IRIX 5.3. I have produced this program as my final year
project for a degree in Computer Science at Heriot-Watt University, near
Edinburgh in Scotland.

The reason for producing this program was the apallingly basic (but I
suppose functional) "SoundEditor" bundled with IRIX 5.3 which is a far too
basic given the advanced nature of the Silicon Graphics Audio.

The program has been designed and developed over the last nine months - but
in parallel with full time lectures :( - and is now at a relatively finished
stage. I thought I might "release" the package, at this point, to all Silicon
Graphics XForms users free of charge and I hope that I'll receive some
feedback, bug reports, suggestions for improvement and general comments on
the package.

I am developing the program over the summer (before I start "real" work in
September) and so feedback and comments would be much appreciated. If my
prospective employers allow me I'll probably even continue development of
the package after that point as well.

So, in other words please, please send me comments and feedback, whether you
think the program is good or a load of .... well not nice stuff. Bug
reports, criticisms and general banter are just as welcomed !!!!

So that's it, no instruction manual, no help file - a fair chunk of the
program is self explanatory, the rest can all be worked out with
experimentation (I hope - if not mail me). Oh, and not all the effects
are functional yet - you'll get a lovely "please register" prompt if
the effect you are trying to execute is not available (ignore this prompt
it was just to look good for my demo to my superviser - there is no
registration !!!). The only effects not working at the moment are gated
reverberation and equalization.

Enjoy, and hope to hear from you all real soon.......

PS  This program was developed using XForms 0.81 on a Silicon Graphics Indy
    running IRIX 5.3 - let me know if you have any difficulties running the
    program and give me details of your setup.

PPS Source is not included yet 'cos there's lots of it and there are still
    bugs to sort out - will include it once it is all working !!

History (well kind of)
----------------------

Since first release :-

* Added ability to load and save effects parameter settings
* Implemented Auto Pan
* Bug fix in time remaining on DSP execute screen
* Two channel mixing, slider fades samples correctly
* Loading of samples,checking for loop markers eased
  (were problems when loading non-looped samples)
* Four channel capability added to entire package - note the
  switch to put the SG into 4 channel mode is on the playback page

Planned Improvements
--------------------

* Multi threading so that audio not stopped by user interaction
* Complete context sensitive help
* Spatialization toolkit
* Direct to disk editing / recording / playback for large audio files
* Linux conversion
