Hi,
For some unknown reason, I seem to be unable to set SND_PCM_FORMAT_FLOAT
format flag when initialising alsa driver. This happens with my both cards
(on is the laptops AC'97 Audio Controller and the other a similar onboard
cart)
This line used to work with alsa 0.9 but return an "Invalid argument" error
with alsa 1.0.14a :
snd_pcm_hw_params_set_format(alsa_pcm_handle, alsa_hwparams,
SND_PCM_FORMAT_FLOAT_LE)
If I remove this line, the driver gets initialised but as integer sample
format, which, of course, generates noise as I'm sending 32bit floats to the
output...
Example code at lines 1031-1041 :
http://cvs.savannah.nongnu.org/viewvc/freecycle/src/soundplayer.cpp?annotat…
Please, please help !

Hi,
Does anyone know the status of Timidity's development aside from the one
posted on its sourceforge website (timidity.sourceforge.net)?
The Japan URL, timidity.jp seems to be down as well for the longest time I
could think of.
In any case, it's still great software and I use it a lot (and will most
definitely continue to use it for some time).
Is the project (almost) dead? Where could we see traces of its life?
Thank you very much.
Best Regards,
Carlo

Hi all,
we are developing Podcast support for Aqualung[1].
At present it is working well for RSS feeds, but we
would like to achieve compatibility with Atom feeds
as well. The problem is, we cannot seem to find
some good feeds we could test for compatibility;
everyone seems to provide their feeds in RSS.
So, can anyone provide some popular (or not)
feeds that use the Atom syndication format?
Thanks,
Tom

Late one friday afternoon, a sound-engineer was sitting in his chair
admiring a brand new pair of flat frequency response monitors. He then
observed the following:
For two frequencies represented by sine-waves and an octave apart to
have the same relative loudness, the higher octave will need to have its
amplitude adjusted to half of that of the lower octave.[1]
Both frequencies will then force a membrane to travel the same distance
within a given timeframe - the higher will go half as far but twice as
often than the lower - and they will also both have the same speed or
steepness at the zero-crossing.
Surprisingly, the lower frequency consumes four times as much energy
than the higher[2], although it is apparently not doing any more actual
work.
Therefore, it is a better excersize to take a walk around the block,
rather than running around in small circles.

With current codebase, none (or minor, non-essential). Main purpose it
to handle hardware devices through raw midi in jackd and alsa seq apps
through a2jmidid simultaneously.

I am posting here since the Jack-Rack Mailing list is looking decidedly
unmaintained.
I have discovered a small bug in jack-rack which I at the moment cannot seem
to find the source of.
Which is that feedback for midi devices is sent one channel greater than it
should be.
IE... If I have a controller set to Channel 1 CC 7
feedback comes back on Channel 2 CC 7
Channel 2 sends midi back to channel 3 and so on.
(the next slider on my controller)

Aarrgh, such a stupid typo ! A corrected version is uploaded now.
And of course the url is:
<http://www.kokkinizita.net/linuxaudio/downloads/AMB-plugins-0.3.0.tar.bz2>
(I'm multitasking, and the number of threads is too high !
It all started when I discovered that someone had stolen
a wheel from my car this night. Whoever it was apparently
felt guilty enough to put the four nuts holding the wheel
back in place.)

And also and update of the AMB plugins:
<http://www.kokkinizita.net/linuxaudio/downloads/AMB-plugins.tar.bz2>.
>From the README:
--------------------------------------------
AMB-plugins-0.3.0 Released 2007.08.27
--------------------------------------------
* Two new plugins added, both second order horizontal
and first order vertical (i.e. six channels).
1979 2nd order Mono panner
1980 2nd order Rotator
* New name scheme introduced, using two numbers:
a,b means horizontal order 'a', vertical order 'b'.
* Plugins are now organised in two files:
ambisonic1.so : first order (6 plugins)
ambisonic2.so : second order (2 plugins)
The install target in the Makefile will remove any
older versions. If you have saved host configurations
(e.g. Ardour sessions) using any of these plugins you
may have to remove and re-insert them.

Something I've been wondering about recently is this - if you implement
a digital filter, how do you maintain stability when it's pushed into
self-oscillation? Most "real" synths seem to put out a slightly clipped
sinewave when in self-oscillation. Might it be as simple as an atan()
clipper in the feedback loop?

I'm resending this mail (something is very wrong somewhere). Sorry if
anybody got a duplicate.
a2jmidid is daemon for exposing legacy ALSA sequencer applications in
JACK MIDI system. It is based on jack-alsamidi-0.5 (jackd alsa seq midi
backend) by Dmitry Baikov. The main purpose is to ease usage of legacy,
not JACK-ified apps, in JACK MIDI enabled systems.
It is tested, and works, here, with current SVN jack. ATM it may or may
not work with other variants.
Planned features/improvements:
* One JACK client per ALSA sequencer client
* Improved build system (autotools) and support (better handling) for
other JACK variants (older MIDI API variants, jackdmp)
* More control on what ports to bridge (currently bridging is fixed to
non-hardware ports).
* Real daemonization with log file, init.d script, etc.
If someone wants to contribute please, contact me, or send patches, or
request inclusion (Gna! a2jmidid project). As usual, packagers are more
than welcome too.
