Please say why. Thanks!

Hi all,
the Aqualung project (http://aqualung.sf.net) opened a mailing list
for development as well as user discussion. I would kindly invite
everyone interested to join the list. I would also like to thank LA
list members for their patience.
Our list is called aqualung-friends. To subscribe, go to:
https://lists.sourceforge.net/lists/listinfo/aqualung-friends
The list is members-only. After subscribing, post messages to:
aqualung-friends(a)lists.sourceforge.net
We are planning to keep the list relatively low-traffic (no cvs diffs,
no daily releases), but we would like to have a separate place for
discussion so as not to flood the general LA lists with our own
troublesome issues.
We now also have a Mantis bugtracker available at:
http://aqualung.sf.net/mantis
I encourage everyone to add bugs, feature requests or whatever.
Thanks for all your support,
Tom

Yes, it could be that the "invention" implements the algorithms
trivially in GPU -- like anyone would implement when getting started
in to GPU programming.
It is like Nokia mobile connected to the wall power outlet.
The Nokia mobile does not take power directly from the wall because
that "invention" is patented. Nokia mobile is forced to take
power from the battery (which could be next to dead). All this
even devices have taken power directly from the wall for decades.
GPU is yet another new gear to play with, just like mobiles.
Anything can be patented, I'm afraid.

The article says quite clearly that the invention is patented.
They would be fools not to try to patent it because the market
is huge.

I have had years this idea of using graphics texture functions to
generate audio noises and signals. This app runs naturally on GPU.

Hi All,
I'm trying to develop a custom wav player app using libao - I need to
keep the audio latency as small as possible in this project. I was
wondering if anybody has done any tests to see how latent libao is for
this, or whether I should just throw in the towel now, and move to
jack/libalsa?
Also I was wondering whether reading each sample at a time from a file
is likely to be dropping the real-time ness, or whether people have
found that this isn't really such a limiting factor.
At the moment it seems quite slow, but then I am developing in vmware-
so I guess that adds quite alot of latency!?

Hi all,
Ok, so I'm playing with osc (currently doing gui->app communication with it)
but all my individual apps still talk midi between them. This is quite
cumbersome, as I want to start having lots of controls that midi doesn't
support - and I don't really "think" in midi these days anyway.
Is there a case now to ditch midi support and go with osc for everything? I
see midi messages are a type within osc anyway - is it fairly straight forward
to be backwards compatible this way?
cheers,
dave

Portaudio, which gives you macos and windows for free (but of course
you must also port the gui stuff...)

Do the callbacks once and it's trivial to port to all three of the above
in my experience.
