is there any application at all like vsound for alsa? i notice that it can't write a buffer from the alsa driver..
i have a half-duplex card on a lappie so i cannot record and play at the same time, hence vsound is very useful to me.
cheers,

* Really fixes the UID clashes.

I will now be walking around with a paper bag over my head for the next

I've been using Linux for quite some time now and finally got around to using
it for audio and MIDI. I must say i'm very impressed with all the
applications i've been using.
Thanks to all (developers and users) for making Linux audio/music development
a reality.

hello to evey body,
i'm new to this list.
I'd like to know more about Unified Audio PLugin Architecture.
I will begin a practical on this topic in mars.
where can I register to a mailing-list or forum or...
I' also looking for papers about audio dynamic
compression/expansion/limiting.
Does anybody have some good links on this topic?
(I'm not looking for "compression for the newbies" but some more in-depth
considerations.
like analog compressor modeling.... aliasing due to non linear
processing.....)
thanx

Hi,
for a project at our radio station I need to simultaneously record two
signals coming from an Amek DMS mixer.
The signals are digital optical S/PDIF (which I assume is the same as
TOSLINK ?).
I am looking for a card or a combination of two cards that would allow me
to record both these signals at the same time under linux. Of course I'd
like to go for the cheapest stable solution possible :)
I've been looking at specs of the Hammerfall Light, it seems to feature
more than one ADAT input port, which from the docs looks to be the same
type of connector as optical spdif. I'm just not very sure from the docs
if this will really work; ie if one Hamerfall Light can record two spdif
signals simultaneously.
One Hammerfall is about in the right price range, two is probably too
expensive :)
So, basically my questions are:
a) will one hammerfall record both optical spdif signals at the same time
?
b) what other, cheaper, card is there that can record an optical spdif
input ? (I looked at some obvious choices, the hercules cards aren't
supported well enough and the sblive cards only take coaxial optical)
Thanks in advance,
Thomas

Well I have changed the name. Now it is "Linux audio professional
support & contacts database". I would prefer to keep it as one page just
to make things easier for me to manage. While I would love for this site
to become extreemely popular and require serious commitment I am
pragmatic that this probably won't happen in the next couple of years.
Splitting the page up at this point seems like more work than neccessary.

I thought about that but I decided multiple lines provides more scope
for presentation purposes. I expect people to eventually treat it
similar to an email signature.

The were some bugs in 0.3.4 so I'm releasing again. Sorry.
* UID clash with flanger and l/c/r delay [serious] - spotted by Bob Ham,
thanks
* SC4 had the wrong label [mild but anoying]
* autoconf script wasn't obeying CFLAGS [mild but anoying]
I believe that SC4 and the lookahead limiter might be causing problems
with some hosts as they have control outs. If you spot problems with these
and think its the host, please contact the author.
I know that ecasound and jack-rack handle it fine.

Hmmm, how do you recon? A sidechain for a compressor may be an audio
stream, but it's the "control" behaviour of that stream that is of
interest, right? That should mean that it would be possible to extract
just the behaviour and only distribute "that".
But I may very well be misunderstanding, this is mostly theory for me, I
haven't had much real practice with this kind of stuff.

An example:
Recording a guitar in mono (Sounds dull). Easy way to make it more
lively is to add an stereo effect, delay is my preference.
For the above example a mono-->stereo plug would suffice, but
stereo-->stereo is more versatile. Muse handles the mono->stereo
conversion internally.
As for parameters I'd like separate delays for left and right, apart
from that I'm open for suggestions... I'm no pro, I learn as I try :).

Ya, working mostly in MusE I'm somewhat limited in the number of
solutions I can try. Currently MusE only supports basic features (pretty
much modeled after Cubase).

The answer is 'badly'. ;)

Pipes are non-deterministic, so banned in LADSPA. The only one thats an

Its an interesting idea.

The same is true of SHM, but if the hosts are not running in sample sync
all hell will break loose.

Ahh, theres a misundersantding about what sidechains do here, they really

Neat idea. Kinda evil though. Very tempting...

What do you want from a stereo delay? There is an left-centre-right delay,
but thats actually a mono delay that takes stereo input and pans the
result. A stereo delay would be easy to implemnt, what controls do you
want?
There is an auto-phaser (sweeping allpass filter), but no auto wah
(sweeping bandpass), or auto panner, true. I tend to build things like
that out of SSM or pd. But there should be complete plugins.
