libnyquist
Library code and the "nyx" interface by Dominic Mazzoni.
Based on Nyquist version 2.29 by Roger B. Dannenberg,
which was based on xlisp 2 by David Michael Betz.
For license information, please see the file LICENSE.txt
libnyquist currently only exists as part of Audacity. For
information on using libnyquist as an embedded audio processor
within another application, contact the Audacity developers:

For information about Nyquist as a standalone, interactive audio
programming language, see the Nyquist website:

INSTALLING NYQUIST
====================
Please see Section 1.1, Page 1, of the Nyquist Manual
If you use Windows 95 or Windows NT, this release was
compiled with Visual C++ 6.0.
For the Macintosh release, there is an executable
Nyquist program in the runtime directory.
IMPLEMENTATION STATUS
=====================
Version 2.29 provides:
new functions: snd-alpassvc, sndalpassvv, snd-eqbandvvv
corresponding high-level functions in Nyquist
new licenses for both Nyquist and XLISP
new NyqIDE implementation
fixed BUZZ function
various bug and documentation fixes
Version 2.28 provides:
include indx.html in doc folder (in files.txt)
fixed compute-default-sound-file in nyquist.lsp to
compute appropriate extension (.wav, .aif)
more code to automate win32 releases
Version 2.27 provides:
makefile.lsp now generates sndfn.wcl & sndfn.cl
fix to include snd-pluck and some others omittted from 2.26
Version 2.26 provides:
bug fix in sampler, negative frequency handling
guard against out-of-order events in TIMED-SEQ
added FMLFO, an lfo with frequency modulation
added SND-SQRT, S-SQRT, SND-ABS, S-ABS functions
new NyqIDE version with S-PLOT function (!)
NyqIDE has better parsing for paren balancing
NyqIDE upgrade to WindowsXP and Delphi 6
NyqIDE increases input string length maximum
NyqIDE prompts on save conflict
added voice-synthesis demo from Eduardo Miranda
corrected absolute path in demos/pmorales/e2.lsp
minor documentation and indexing improvements
pointer to demo docs goes on start menu now
Version 2.25 provides:
new way to provide search path: set *SEARCH-PATH* to a string,
e.g. (SETF *SEARCH-PATH*
"C:/program files/nyquist/runtime,c:/program files/nyquist/lib")
allowing Nyquist to be run without setting registry.
Version 2.24 provides:
text editing for command lines in Linux version
Version 2.23 provides:
bug fix in (current-path) for Mac
fixes to some Mac sources corrupted in 2.22
Version 2.22 provides:
documentation (HTML) included in release now
bug fix for Mac console output exceeding 32K limit
protection from playing very high sample rates in Win32
(crashes in Windows MME library!)
change s-save to take :endian rather than :swap parameter
pianosyn.lsp runs on the Mac now
demos/examples.lsp generates audio with "normal" sample rates
Version 2.21 provides:
s-plot uses gnu-plot in Linux
separation from CVS -- I just couldn't keep beating my head
against the wall
Version 2.20 provides:
improved Macintosh support
Version 2.19 provides:
integration of Macintosh code (from v2.12)
addition of PLUCK and BUZZ synthesis functions
Version 2.18 provides:
bug fix in midifile read routine under Linux
Version 2.17 provides:
bug fix for long line input under linux and windows
biquad filters
hzosc osc-tri osc-saw osc-pulse -- new oscillator variants
bug fix for reading in non-AIFF files with 'FORM' headings
extension to s-read to support explicit byte-swap parameter
Version 2.16 provides:
bug fix in tables (lookup oscillators and other functions)
Windows GUI version of Nyquist
Version 2.15 provides:
port to Linux
Version 2.5 provides:
more signal processing functions
Version 2.2 provides:
ports to more systems including Win32 (Win95 and NT)
bug fixes
more signal processing functions
improved sound I/O subsystem
Version 2.1 provides:
bug fixes
documentation and code for user extensions
Version 2.0 provides:
continuous time warps
many more functions
bug fixes
The distribution may contain sources for Nyquist. If not,
you got the runtime distribution, and there is a source version
available.
A number of "source" files are machine generated, including:
- many .c and .h files that implement signal processing functions.
These are generated by translation system that converts
.alg files to .c and .h files. .alg files give high-level
descriptions of DSP algorithms.
- Makefile.* is generated by "makefile.lsp".
The status is:
System Status
RS6K = RS6000, AIX untested, but used to work
NEXT = NeXT 3.0 (Cube) untested, but worked fine on a previous version
SGI = ??? untested, but used to work
PMAX = Mach 2.5 on Dec workstation
untested, but worked in previous version
SPARC = Sun Sparc ??? untested - previous version of Nyquist DID work
LINUX = Linux tested
Win32 tested
Mac tested
If you have problems running Nyquist on a Unix machine, I'd be happy to
help. I can give you advice or if you give me an account, I can log in
remotely and install Nyquist for you. If you make corrections yourself,
please let me have them so I can put them in the next release.
DIRECTORY STRUCTURE
===================
cmt - CMU MIDI Toolkit files, used by Nyquist for MIDI File I/O
demos - Nyquist demos go here
fft - some fft functions
lib - .lsp files offering extensions to Nyquist
misc - various files and programs used to implement Nyquist
nyqsrc - general Nyquist source code (mostly in C)
runtime - the Nyquist and XLisp runtime code (mostly in XLisp)
sys - system specific files
