Hello all,
I'm looking for some alpha testers for a small application
that I wrote to test the DSP core of Aella, the convolution
and reverb processor announced at LAC2006.
If you are using Jace then Jconv will be familiar as it uses
the same configuration files.
Candidate alpha testers please drop me a line !
>From the README:
Jconv - Alhpa release - for testing only.
Jconv is a Convolution Engine for JACK using FFT-based partitioned
convolution with multiple partition sizes. It's a command line version
of what will be the core of Aella, but without the special reverb
feautures, preset management, reverb envelope editing etc. that
Aella will have.
Jconv uses a configurable smallest partition size at the start of the
impulse response, and longer ones further on. This way you can have
long impulse responses _and_ minimal or even zero delay at a reasonable
CPU load. This would be impossible using just one partition size.
Processing for partition sizes larger than Jack's period size is
delegated to up to five threads running at real-time priorities just
below that of Jack's audio threads. CPU load generated in such threads
will _not_ show up in Jack's DSP load figures.
If you set the smallest partition size equal to JACK's period, there
will be zero processing delay. Otherwise the processing delay is
2 * smallest_partition + period_size.
Jconv will do any convolution matrix up to 64 inputs by 64 outputs,
as long as your CPU can handle it. It doesn't waste any memory or
CPU cycles on empty cells in the matrix, nor on empty parts of an
impulse response. Maximum length for each convolution is 30 seconds.
Jconv can easily generate 100% CPU load at real-time priority. This
will in most cases not stop audio processing, as the load will be at
lower priority, but it will lock up everything running at normal
priorities such as your terminals or desktop. Don't panic - jconv
will detect the situation and bail out after a second or so.

ARDOUR 2.0 RELEASED FOR OS X AND LINUX
Philadelphia, USA April 30th, 2007
The developers of Ardour are happy to announce the release of version
2.0 of the award winning digital audio workstation. Ardour transforms
any computer running Linux or OS X into a tool to record, edit and mix
multi-track audio. You can produce CDs, mix video soundtracks, or just
experiment with new ideas about music and sound. Version 2.0 is
available as an OS X (10.4) universal package
(http://ardour.org/files/releases/Ardour-2.0.dmg) and also as source
code (http://ardour.org/files/releases/ardour-2.0.tar.bz2). Linux
distributions will have prebuilt binaries available in the near future.
Nearly 2 years of work have gone into this new version. Along the way
a huge number of bugs were fixed, performance and workflow were
improved, and many new features were added. Highlights of version 2.0
compared to the last stable release (0.99) include:
* new user interface featuring:
- more accessible menus
- improved overall GUI design
- instant accelerator key rebinding direct from menus
* destructive recording ("dubbing") capabilities (as used by
the new Harrison Xdubber)
* undo/redo across program startup/shutdown
* redesigned and more stable support for VST
* support for 24 bit integer native files in addition to
32 bit float as in 0.99
* modular support for hardware control surfaces, including the
Frontier Designs Tranzport and Mackie Control Protocol devices
In addition there are literally hundreds of minor fixes and smaller
features that have accumulated during the work on 2.0. This new
version is fully backward-compatible with older releases of Ardour,
and can be installed in parallel with them. Please note that older
versions cannot load sessions saved by Ardour 2.0.
With the release of 2.0, the project's development will accelerate as
it returns to focusing on major features and workflow. We also look
forward to the results of this summer's Google Summer of Code projects
involving MIDI editing and surround panning. We expect to release
version 2.1 within a few months, containing new features that have
been under development but were not merged into this release.
Ardour is available for free download from the ardour.org website. We
encourage users to support the development of the software through
subscriptions and donations. The software itself is available free of
charge.
ABOUT ARDOUR
Ardour capabilities include: multichannel recording, non-destructive
editing with unlimited undo/redo, full automation support, a powerful
mixer, unlimited tracks/busses/plugins, `persistent undo',
multi-language support, destructive track punching modes, timecode
synchronization, and hardware control from surfaces like the Mackie
Control Universal. The program has a completely flexible "anything to
anywhere" routing system, and will allow as many physical I/O ports as
your system allows. Ardour supports a wide range of audio-for-video
features such as video-synced playback and pullup/pulldown sample
rates.
Started in 2000 by one of the founding programmers at Amazon.com,
Ardour is developed by a worldwide group of programmers with testing
and feedback from a widely distributed network of musicians and audio
engineers. Running on Linux and OS X, it strives to meet the needs of
professional users. Ardour has received commercial sponsorship from
major console manufacturers, Google and others. Many of Ardour's
developers have also participated in the development of JACK, the de
facto standard for inter-application audio routing on OS X and Linux.
Ardour is released under the GNU Public License (GPL), providing its
users the ability to freely modify, redistribute and learn.
