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

Welcome to the Digital Audio Processor, otherwise known as DAP. This
program was originally produced as my final year project for a degree in
Computer Science at Heriot-Watt University, near Edinburgh in Scotland.
Since then I have been changing and improving DAP, attempting to make it
the best sample editor and processor available on the UNIX platform. It
still has a long way to go though !! 

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

What is DAP ?
-------------

DAP is a comprehensive audio sample editing and processing suite. DAP
currently supports AIFF and AIFF-C audio files, 8 or 16 bit resolution
and 1, 2 or 4 channels of audio data. Note however that on Linux and
Solaris, compressed AIFF-C files are not currently supported, only
non-compressed AIFF and AIFF-C files.

The package itself offers comprehensive editing, playback and recording
facilities including full time stretch resampling, manual data editing
and a reasonably complete DSP processing suite. Note however that time
stretching does not currently work on Solaris.

Using DAP with Sox
------------------

For compatibility with sox, the popular audio conversion tool, the
"copyright save" preference must be switched off in DAP. Switching this
option off simply tells DAP not to save copyright strings. This is
necessary as the latest version of sox is rather buggy and doesn't
like copyright strings.

Requirements
------------

To run DAP you must have the latest release version of xforms (0.86)
installed on your system. Note that the latest test version of xforms
(0.87) is incompatible with the tooltips system employed by DAP and
thus it is not recommended that this version of xforms is utilised.

See http://bragg.phys.uwm.edu/xform

For Linux and Solaris you will also require the Open Sound System (OSS)
audio drivers to be installed properly. These drivers are normally
supplied with Linux but Solaris users will have to install them
manually.

Compilation and Installation
----------------------------

For details on compilation and installation check out the INSTALL file
contained in this directory.

And finally
-----------

Please send me comments and feedback, whether you think the program is
good or a load of cobblers. Bug reports, suggestions, criticisms and
general banter are just as welcomed !!!! 

So that's it, no instruction manual or help file (yet). 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 the demo to
my project supervisor - 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....
