From: fingerhu@ircam.fr (Michel Fingerhut) Subject: IRCAM DSP software for DEC/ALPHA and DEC/MIPS Organization: Inst. de Recherche et Coordination Acoustique/Musique, Paris Date: Fri, 13 Aug 93 11:25:23 GMT
ftp.ircam.fr:/pub/IRCAM/programs contains some of the IRCAM-developed software packages (in demo version; see further down for availability of the fully functional versions), including runnable binaries for both the DEC/ALPHA (osf1) and DEC/MIPS (ultrix) architectures, and soon available on other platforms (SGI and Macintosh).
MAX
MAX is a visual, object-oriented, programming language, initially designed for interactive musical performance, but which is suitable for digital signal processing as well as real-time control. It allows interconnecting of oscillators and filters, building custom controller modules and simulation units all from a core collection of signal processing objects.
First developed by Miller Puckette at IRCAM in late 1986 to control the IRCAM 4X, it was later implemented on the Apple Macintosh as a graphical programming environment for MIDI applications. This version has been extended by the Opcode company in Palo Alto, CA (USA), and is available through them.
The Alpha version (and its demo-only subset) is based on the NeXT version, where it is used to control the IRCAM-designed ISPW board. This card, based on two Intel i860 microprocessors, handles numerically-intensive real-time operations.
To date, it has been extensively used in live performance of full-length musical compositions (see some references in the MAX/doc directory), as well as in scientific and experimental applications requiring real-time control.
SVP
SVP (``Super Vocodeur de Phase'') is a signal processing tool which was designed and developed at IRCAM by Gilles Poirot and Philippe Depalle. It is a full system for the analysis and synthesis of sound, whose core is a phase vocoder, and which comprises several modules for analysis (FFT, LPC..), filtering (band modes, surface modes...), time- scaling, mixing, spectral combination, cross-synthesis and amplification, which can be combined in multiple ways.
UDI
UDI is a library of C routines which provides a coherent software approach for developing and maintaining digital signal processing algorithms on stand-alone workstations or on host/array processor configuration. Initially designed for sound signal analysis and synthesis, it can be used by any application which does vector math calculation.
It provides functions ranging from elementary vector and matrix operations to more specific DSP operations, such as, but not limited to, FFT, least-square, linear prediction coding, discrete cepstrum and pitch detection.
UDI was actually used in implementing SVP.

and h _o _s _t _ is the fully-qualified name of the machine you are currently calling
from, which is not necessarily the one on which you get your mail. If you
mistype it, the ftp server will advise you with an informative error message.
