[linux-audio-dev] HDSP 9652 minimum buffer size

by Wolfgang Woehl

Paul, Thomas, What are the constraints for the HDSP 9652's apparent minimum buffer size of 64 frames? Is it the FPGA? Is it the firmware? Wolfgang

[linux-audio-dev] debugging realtime issues with instrumented kernel

by Robert Jonsson

Hi, I recall someone (Lee?) mentioning something along the lines of using a recent kernel with Ingos patches to get feedback on realtime problems of your own code. It sounded very interesting! Now, I can't for the life of me find the message, if someone knows anything about this I would very much appreciate some more information, are there any links? Thanks in advance, Robert -- http://spamatica.se/musicsite/

[linux-audio-dev] Re: linux-audio-dev Digest, Vol 19, Issue 33

by Ian Howard

Andres, and all, A very interesting idea, though here in West Africa, the main limitation in Linux adoption is not a lack of modem support, it is more to do with a lack of knowledge about Linux and open source, and too many aid and commercial organizations only touting or buying proprietary product. Here there are very few computers at home and even fewer people who can afford the incredibly expensive phone costs, that is the main reason that few modems are used here. Those who can, can afford hardware modems that supports Linux, as the monthly phone bill will well exceed. I was at an internet cafe recently, who had to shut-down because in one month their phone bill was over $350, twice their revenue. So, I think that though this is a solid idea, and that it might have application in some developing countries, here in West Africa modems and phone lines are the last choice due to their expense.

[linux-audio-dev] crazy idea...

by Lee Revell

I had the idea the other day that you could theoretically implement a Winmodem driver as a JACK client. All you would need is an ALSA driver that exposes the hardware part of the modem as a sound card, a mechanism to inject the resulting bits back into the kernel networking layer, and the DSP knowledge to implement a software modem... This is almost completely pointless, but might be an interesting CS project. Lee

[linux-audio-dev] more on live cds

I should have mentioned that I'm certainly interested in any other non-agnula live cd solutions as well. Thanks Iain

[linux-audio-dev] customizing agnula live cd?

by Iain Duncan

Hi, wondering if this might tickle anyone's fancy on the agnula team. The agnula live cd is a great idea. I would love to be able to customize that however, to add my own apps, and of course data files. I play live shows using csound5, but would like to add jack, jammin, ladspa plugins etc, and some of my custom apps. So obviously I need to be able to add all those, and all the orc and sco files and any samples. Is there or could there be a relatively straight forward way of customizing the agnula live cd, perhaps a script or app that allowed one to make a custom version on a small partition and then burn it or something. I figure that would be fantastic for shows in case of hardware failure, disk failure, or even stolen machine as one could essentially do your show off someone else's pc if need be. It would be really sweet if you could count on it recoginizing and being happy with all major sound and midi cards, etc. Any thoughts, pointers, etc? Thanks Iain

[linux-audio-dev] Denemo 0.7.3beta2

by Aaron

Hi all, For all music notators out there, there is a new release of denemo (denemo.sourceforge.net). It has lots of improvements including the graphical interface and added functions. So if you are a denemo user now is a good time to get the latest and greatest. I am using the cvs which has already a bunch of bug fixes since the release, but either way it is quite an improvement from the previous release, with 50 undo's! Best wishes Aaron

[linux-audio-dev] spectral peaks curve

by Andrew Gaydenko

Hi! Is there some tool to accomplish such task: take some sound (wav) file and plot (or give some kind of table) peak spectrum values along all the file in given frequency range? Andrew

[linux-audio-dev] LCA2005

by Dave Robillard

Hi all, Anyone going to LCA2005? (note that's LCA in Australia, not LAC in Germany!) I'd like to see if I can find a keyboard controller and/or guitar for my presentation (not to mention the jam session afterwards). I'm flying in from Melbourne and can't bring any of that stuff. Keys in particular would be /really/ nice to have, if there's any Canberra folks around. .. thought I'd ask. :) Regardless, drop your name in this thread anyway - it'd be nice to have something of a roll call Cheers, -DR-
