Libraries:

• pa_sgi
  I contributed to the portaudio library, mainly involving the support for Silicon Graphics IRIX.

• rdmid
  Read a standard MIDI file in the C programming language.

• wraiff
  Write an AIFF soundfile in the C programming language.

• wraiffpp
  Write an AIFF soundfile in the C++ programming language.

• rdaiff
  Read an AIFF soundfile in the C programming language.

• rdaiffpp
  Read an AIFF soundfile in the C++ programming language.

• polynom
  Complex polynomial factoring and expansion in C++.

• SRC
  Simple Rate Converter in C.
  64-bit transparent (integer DSP) multichannel sample rate converter.

Code examples:

• synth
  How to build a (non-realtime) synthesizer that reads a MIDI file in the C programming language.

• ks
  Simple string simulation (using the Karplus-Strong algorithm) in the C programming language.

• kspp
  Extremely simplified guitar simulation in the C++ programming language.

• pa_karplus-strong.c
  Realtime portaudio karplus-strong example in C.

• spliff
  Cross-platform AIFF file splitting utility. Splits multichannel files to mono files. Sourcecode in the C programming language, using the abovementioned rdaiff and wraiff libraries.

• cropaiff
  Cross-platform AIFF 'silence cropping' utility. Cuts away leading and trailing silence in multichannel audio files. Sourcecode in the C programming language, using the abovementioned rdaiff and wraiff libraries.

• CD click detect
  CD ripping glitch detection (in C).

• Haskell
  My first steps in Haskell...

DSP:

• ComParser
  Realtime audio recognition and pseodo-score-following. Free and open source software using portaudio to enable audio input on all platforms.
  
  
• PoZeTools
  Tool for digital filter design. Calculates time coefficients and visualises responses in both frequency and time domain. You can quickly try out by visiting (and perhaps clone) this  online pole-zero webservice.
  
  
• Spectroscopic Toolkit
  64 bit integer DSP for massive additive synthesis and granular synthesis. ANSI C source code available. Tested on UNIX and Macintosh, and probably easy to port to Windows, BeOS, Linux, etc. High frequency-accuracy, supporting nanotonality.
  
  
• Sound Processor
  Real Time Digital Signal Processing software for Apple Macintosh equipped with old Digidesign cards (for Nubus cards only, for example Mac Quadra 650, MacIIci, etc.).
  
  

Psycho Acoustics:

• Kameoka and Kuriyagawa Dissonance
  In 1994, I implemented the sensory dissonance model of Akio Kameoka and Mamoru Kuriyagawa. The Pascal programming language was used and it runs under DOS. I applied the model in some electronic compositions.

Internet:

• wikiC
  A standalone wikiserver in pure C (no webserver, database and scripting needed).
  
  
• UPLOAD
  Simple file upload tool. Allows a group of people to work together, in a shared directory on a webserver.
  
  
• EVAL
  Polling tool, utilizing e-mail and the web for automated surveys.
  
  
• BUYCD
  Old, obscure and probably useless: online audio-CD selling software. CGI source code in a bit messy C and JavaScript. Customers may put together their own CD's and/or buy instant-CD's.

Miscellaneous:

• UNSPACE
  Renaming tool for massive removal of whitespace in file- and directory-names.
  
  

Precompiled for IRIX 6.5:

• abcm2ps
  Jean-François Moine's abcm2ps version 3.7.21 compiled for IRIX 6.5.
  
  
• libsndfile
  Erik de Castro Lopo's libsndfile version 1.0.11 compiled for IRIX 6.5.
