Eric Mrozek's Audio/DSP Page
NextMusic was an effort in the early 1990s to disseminate information
about music and DSP related topics in the world of NeXTStep/OpenStep.
There are several ways to get information:
Audio Compression
- The NextStep Sound and Music Program List
contains information and descriptions of most of the audio and DSP applications
available for the NextStep/OpenStep operating system (and also generic C,
C++, and Objective-C libraries).
- ICMA's Software Links to non-commercial software for computer music researchers and composers.
- The Sound Processing Kit is a C++ class library for audio applications.
- SOX is a sound file format converter for Unix and DOS ("It's the swiss army knife of sound tools"). You can get the source [141K, gzipped tar file, version 11 gamma]
or a DOS executable
[63K, zip archive, version 10].
- Princeton Sound Kitchen has a buch of apps and applets for manipulating sound.
- At the CCRMA site:
- The Calliope music notation editor runs on NextStep.
- SynthBuilder runs on NextStep. Staccato Systems is porting it to Windows.
- The abc home page describes a language designed to notate tunes in an ascii format.
The ability to write tunes in abc notation means that they can be easily and portably stored or transported electronically.
There are several typesetting interpreters described at
http://www.ceolas.org/tunes/#abc
and http://www.gre.ac.uk/~c.walshaw/abc/#software.
One particularly interesting package is abc2ps which interprets abc to postscript.
There is also a multi-voice variant called abcm2ps.
I have compiled several versions of each for Win95.
- Using Brendan Breathnach's indexing system within the abc format.
- MiscKit contains some sound objects.
- An HTML version of the CSound Manual
- Martin Dupras' maintains a Csound Page which contains a FAQ, info on joining the mailing list, and pointers to other Csound info.
- An archive of mac sound processing tools in Norway, including PowerPC-native Csound.
- The official site for Motorola's Dr. BuB archives (programs for their DSP chips) points to files formatted for PCs and Macs.
- Jim McLaughlin has written several good CD-ROM utilities for grabbing digital audio off of audio CDs on DOS and Win95 platforms.
- Syntrillium's Cool Edit Pro is a multitrack digital audio recorder, editor, and mixer for Win95.
- FFTW is a free C subroutine library for computing the Discrete Fourier Transform (DFT).
- Jeff O'Neill's collection of software for time-frequency analysis.
- David Jaffe is a composer and the author of the MusicKit.
- Charle's Dodge is a coauthor with Thomas A. Jerse of Computer Music, Schirmer Books, 1985. A second edition in progress for 1995.
- James Beauchamp works with musical sound analysis/synthesis at Univ of Illinois - Champaign.
- CCMRC (Center for Computer Music Research and Composition)
- The Stanford Center for Computer Research in Music and Acoustics (CCRMA) - Areas of ongoing interest include: Composition, Synthesis Techniques and Algorithms, Physical Modeling, Signal Processing, Digital Recording and Editing, Psychoacoustics and Musical Acoustics, Real-Time Applications and Controllers, Collaborative Works with other Art Disciplines and Music Manuscripting by Computer.
- CEMI (Center for Experimental Music and Intermedia)
- CNMAT (Center for New Music and Audio Technologies)
- CRCA (Center for Research in Computing and the Arts)
- CSMT (Center for Studies in Music Technology)
- IRCAM (Institut de Recherche et Coordination Acoustique/Musique)
- Laboratory of Acoutics and Audio Signal Processing (Helsinki Univ. of Tech.)
- The goal of the Machine Listening Group of the MIT Media Lab is to create machines that can understand the myriad sound cues in natural acoustic environments, and that can simulate such environments for applications in virtual spaces. Their work involves the modeling and measuring of human perceptual phenomena, and the use of sophisticated techniques from signal processing and pattern recognition to analyze sound.
- Music Research Lab (Univ. of Helsinki)
- NoTAM (Norwegian network for Technology, Acoustics and Music)
- RealAudio
- ICMA - Computer Music Association and the annual conference.
