[LAD] FAUST 0.9.10

                            ================
                            | FAUST 0.9.10 |
                            ================

GRAME - Centre National de Creation Musicale - is happy to announce
the release of FAUST 0.9.10. This version introduces several new
possibilities. It is the first official release to offer full
parallelization of the C++ code to exploit multicore architectures,
as well as automatic generation of mathematical documentation.

-------------
About FAUST :
-------------

FAUST (Functional Audio Stream) is a functional programming
language specifically designed for real-time signal processing and
synthesis. A distinctive characteristic of FAUST is to be fully
compiled. The FAUST compiler translates DSP specifications into
very efficient C++ code that works at sample level. It targets
high-performance signal processing applications, libraries and
audio plug-ins for a variety of audio platforms and standards. A
same FAUST specification can be used to easily generate native
JACK or ALSA applications, as well as CSOUND, LADSPA, MAX/MSP, PD,
Q, SC and VST plugins.

The Faust distribution can be downloaded at:
http://sourceforge.net/projects/faudiostream

Two mailing lists are available:
https://lists.sourceforge.net/lists/listinfo/faudiostream-devel
https://lists.sourceforge.net/lists/listinfo/faudiostream-users

In order to test FAUST without installing it, please refer to the
Online Faust Compiler:

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

A) C++ Code Generation
------------------

The Faust compiler translates Faust programs in C++. Several new
options have been added to control how the C++ code is generated,
in particular :

- control of the floating point precision : single (default),
  double, quad

- code re-organization in simple loops to facilitate automatic
vectorization

- automatic parallelization based on OpenMP

- automatic parallelization based on a specific "Work-Stealing"
algorithm

B) Mathematical Documentation
-----------------------------

Using formal methods the Faust compiler can produce automatically a
complete mathematical documentation of a Faust program. This
mathematical documentation is generated in Latex. It includes
equations, block-diagrams and listings. The documentation can be
customized by the user via <mdoc>...</mdoc> tags inserted in Faust
programs.

This documentation can be used to :

- preserve on the long term a Faust program in a purely
mathematical form, independently from Faust or any other
programming language

- bring some help to understand and debug a FAUST program by giving
the equations of each output signals according to the input signals
and the user interface parameters.

C) Language Extensions
----------------------

- Sequential composition operator (A:B) has been restricted to
expressions so that outputs(A) = inputs(B). This restriction has
several advantages. It improves error detection, makes the code
easier to understand and provides nicer and simpler formal semantic
( A:B is B o A)

- User interface labels can now contain metadata. For example the
label "volume[unit:dB][tooltip:control the output volume of the
reverb]" contains two metadata, a unit definition and a tooltip
message than can be exploited by an architecture file to fine tune
the user interface.

- User interface labels can contain absolute and relative pathnames
to better control the hierarchical structure of the user interface.
For example the label "../volume" points to place the widget one
group higher in the hierarchy.

D) New Audio Architectures
--------------------------

Several new audio architectures have been included, in particular
Action Script, CoreAudio, CSOUND, Chuck, Pure, SND-RT, for a total
of about 20 different plateforms now supported :

- Action Script

- Alsa

- ChucK

- CoreAudio

- CSOUND

- Jack

- LADSPA

- Matlab

- MaxMSP

- Octave

- OSS

- PortAudio

- Pure

- PureData

- Q

- Sndfile

- Snd-RT

- SuperCollider

- SynthFile

- VST

- VSTi (mono)
