Hello everybody,
it's again time for a new Ecasound release. Full details follow:
---
1. Summary of changes
Serious bugs in multitrack sync code, ECI C implementation and
big-endian platform support have been fixed. Support has been
added for input and output of FLAC, AAC and M4A files. Improvements
have been made to both FreeBSD and Mac OS X support. Many minor
improvements to ECI implementations and user documentation.
---
2. What is Ecasound?
Ecasound is a software package designed for multitrack audio
processing. It can be used for simple tasks like audio playback,
recording and format conversions, as well as for multitrack effect
processing, mixing, recording and signal recycling. Ecasound supports
a wide range of audio inputs, outputs and effect algorithms.
Effects and audio objects can be combined in various ways, and their
parameters can be controlled by operator objects like oscillators
and MIDI-CCs. A versatile console mode user-interface is included
in the package.
Primary platform for running Ecasound is GNU/Linux. Ecasound can
also be run on many UNIX-derived systems such as FreeBSD, Mac OS X
and Solaris. Limited support for Windows is available through
Cygwin. Ecasound is licensed under the GPL. The Ecasound Control
Interface (ECI) is licensed under the LGPL.
---
3. Changes since last release
* FLAC support added. The 'flac' tools is used for both
encoding and decoding.
* AAC/M4A/MP4 support added. The 'faad' and 'faac' tools are used
for encoding and decoding.
* Improved support for both FreeBSD and Mac OS X. Ecasound should now
compile out-of-the-box on recent releases of these systems.
* A critical bug was fixed in multitrack-offset calculation code.
This bug was triggered by ALSA devices that limit playback
period count to two (for example rme9652 and cs4281).
* Minor fixes to both mp3 and ogg input support.
* Many improvements to the C ECI implementation: Bug which caused
losses of sync between clients and the engine was fixed. Float
return values are now returned with higher precision. These
improvements affect all ECI implementations that are based on
libecasoundc (Perl, Python, PHP interfaces).
Full list of changes is available at

Audio software for Linux!
http://plugin.org.uk/timemachine/
Timemachine is a JACK app for recording sounds that have just happened.
It can also be used as a generic JACK sound recorder. Read the website for
more retails.
This version adds:
Interactive command line mode by Mario Lang (no X11 needed)
Generates WAV as well as W64 files, extension is now right
Can specify JACK ports to connect to on the command line
Enjoy,

WORKSHOP 1: REAL-TIME SYNTHESIS AND AUDIO PROCESSING USING PD
Miller Puckette, University of California at San Diego, USA
Sunday, October 31, 1:00 PM - 3:30 PM
USD 40 / EUR 32,50
Pure Data (Pd), available for Mac, Windows, and linux, offers
real-time audio processing and synthesis, a Max-like GUI, and a very
high degree of integration between control, audio, video, and I/O
operations, in an extremely light package. This workshop, intended for
people familiar with software synthesis but not assuming any
particular technological background, will show what Pd is like and how
to get started with it. Time permitting, the more shown.
Miller Puckette was the top scorer in the 1979-1980 William Lowell Putnam
Mathematics competition and was awarded Putnam and NSF fellowships to
study mathematics at MIT and Harvard, where he finished his Ph.D. in
1986 under Andrew Gleason. From 1979 through 1986 Puckette also
studied computer music with Barry Vercoe at the MIT Media Lab. He then
joined IRCAM in Paris, where he wrote the Max graphic programming
language, which has become the lingua franca of live computer music.
In 1994 Puckette joined UCSD where he is now professor of music and
associate director of the Center for Research in Computing and the
Arts. Puckette's research interests include human-machine interaction
strategies and real-time audio and video processing.

Hi!
I am happy to announce polypaudio 0.6. Chnages:
- TCP wrappers support
- don't load the complete sound file into memory when playing back using pa_play_file()
- autoload API changes;
- don't load all sound files as FLOAT32
- shorten default buffers
- client-side latency interpolation
- add new user volume metrics
- add module-tunnel, module-null-sink, module-match and new tool paplay
- new API version macros
- many client API improvements
- correctly lock cookie file generation
- correctly lock daemon autospawning
- print daemon layout to STDERR on SIGHUP
- new options for pacat: allow sample type specification
In related news: I released gst-polyp 0.1, the first incarnation of a
polypaudio driver for GStreamer:

Greetings:
The Quick Toot series has acquired another fine tutorial, this one
from Ron Parker. It's all about "loud" mastering, you can find it and
read all about it here:

Thanks Ron !
Best regards,

Wow what great responses.
I got a perl script a one line shell script and using qsort (new to me)
and a few apps.
Even more than I even hoped for.
Thanks
I will try them out and see which glove fits the best tomorrow.
Thanks to everyone who supplied a solution

Hi!
I have been thinking about transfering the concept of a
cursor from text editing to MIDI editing.
Since this not specific to any existing sequencer I like
to present my concept here, in hope of feedback and
maybe some project picking it up.
http://wrstud.urz.uni-wuppertal.de/~ka0394/forum/04-10-25_cursor.png
The red, turned H is the cursor. The row (note) it's on
is always marked/highlighted.
The cursor can be moved with cursor keys or placed by
left clicking (just like a text cursor).
Selection of events happens by rubberbanding per mouse
or by using shift + cursor keys.
New notes can be inserted at the cursor location
by just hitting enter, using a default value or the
grid resolution for the length when nothing was
selected. Or filling the selected area with the new
note (empyt space is treated like whitespace in a
text).
Selected events can be moved with the cursor keys
by holding down Ctrl.
There could be auto-selection of the closest event
when nothing else was selected.

Greetings:
Alex Prokoudine sent this link to some interesting photos and info
concerning Russian (pre- and post-Soviet) synths:

Thanks Alex !
Best,

There is a new release of my plugin collection.
Bugfixes: (I've lost the attributions, appologies to the fixers!)
reverse delay - denormal fix
flanger - stability problem
multiband EQ - problem running multiple instances in one host
Sorry, I didn't manage to get through the TODO list.
New plugins:
artifical latency plugin - mainly useful for testing
crossfader - not really tested, may work
There is a new build system (libtool based) that should make it easier to
port to other platforms, but may cause problems.
Enjoy,
Steve

Alternatively to what I wrote a little earlier, a search on freshmeat for
"mp3 find duplicate" gave these two tools:
mp3dup: http://mp3dup.xmms.org/
fdmf: http://www.w140.com/audio/
Never tried these, but maybe that helps you..
