[LAD] [ANN] Faust 0.9.9.4

[Yann Orlarey]

Grame - Centre National de Creation Musicale - is pleased to announce the
release of Faust 0.9.9.4.

Faust AUdio STreams is a powerful and expressive functional programming 
language
for realtime audio signal processing. The Faust compiler translates DSP
specifications into efficient C++ code.

A variety of platforms and plugin formats are supported. A single Faust
specification can be used to easily generate JACK and ALSA applications, 
as well
as LADSPA, MAX/MSP, PD, Q, SC and VST plugins. In addition to C++ code, the
Faust compiler can also generate SVG block-diagram representations as 
well as
XML descriptions.

To easily test Faust before installing it, please refer to
http://faust.grame.fr. The Faust distribution can be downloaded at
http://sourceforge.net/projects/faudiostream. Debian and rpm packages 
are also
available from Debian, Ubuntu, Planetccrma and Packman.

Please note that Faust can now also be used from within the CLAM 1.2 
audio and
music application development framework (http://clam.iua.upf.edu/) and the
Snd-rt 0.8.9.13 realtime music programming environment
(http://www.notam02.no/arkiv/doc/snd-rt)


------------
What's new :
------------

* Syntax modification allowing unary operator - with identifiers (-x is now
allowed)

* Parametric string can now contain the number of digits to use. In the 
string
"line %2i" %2i will be replaced by the value of i using at least 2  digits.

* New fvariable declaration : possibility to declare an external C 
variable of
block variability.

* Redefinition of symbols is now considered an error instead of a simple 
warning

* New syntax highlighting for TextWrangler (Macintosh)

* snd-rt-gtk.cpp: a new architecture file to use Faust with snd-rt.

* synthfile.cpp: a new architecture file to generate audio files 
(contributed by
Dominique Fober)

* osc.lib: a new oscillator library containing fast filter-based oscillators
(contributed by Julius Smith)

-----------------
What's improved :
-----------------

* new additions to filter.lib and  effect.lib :  Piano dispersion filter,
fifth-order fdelay5, notch filter, Second order transformer-normalized 
digital
waveguide resonator... (contributed by Julius Smith)

* Improved jack-gtk.cpp architecture file allowing to control the default
connexions and to run several instances of the same program (contributed 
by Fons
Adriaensen)

* Huge speedup of type inference system for complex expressions by using
memoization and recursiveness information


------------
Bugs fixed :
------------

* Bug correction in the type inference system of recursive expressions

* Better sharing of slow expressions appearing delayed

* Avoid division by zero and report error when block-diagrams  with no 
inputs or
outputs are used in merge and split compositions

* The Faust compiler and some of the architecture files have been updated to
replace char* parameters by const char* when appropriate
