Ok, Apparently forum addicts have decided to hijack this thread though, the original question was : do you want LA* _lists_ (LIST is the keyword here, can't stress it enough) to be moved to linuxaudio.org. I have noting against the idea of a forum, the people interested in this are free to build and maintain one and eventually discuss it with Ico.

[linux-audio-dev] LAD/LAU/LAA/Consortium/...

by Predrag Viceic

Hi, Sorry for crossposting, which is intentional. See below ;) I personally think that this multiplication of LA lists is not a good thing. The idea, proposed by Ivica, which politely suggests the migration of all those lists to an unique one seems very good to me. I would even suggest the usage of a forum (à la php-forum) for information sharing. Those forums would allow multiple topics (LAD, LAA, LAU, Ardour, Rosegarden, MuSE, Jack, ... ) and in the same time facilitate the research, the tracking of topics and the most important thing, would allow the linux newcomers to see all the work done in those lists. I hope that I'm not irritating anyone by suggesting the above, but we are all conscious of the fact that linux audio is still a niche "market" so having an unique point of access to the posts would really be awesome.

[linux-audio-dev] Recommended books for new audio developers

by Damon Chaplin

Hi, What are the recommended books to read for people new to audio development? (Covering things like synthesis techniques, effects processing and basic acoustics stuff.) On the bottom of the Documentation section of linux-sound.org I found these 2: Computer Music Tutorial by Curtis Roads (1995, 1254 pages) Computer Music: Synthesis, Composition, and Performance by Charles Dodge and Thomas Jerse (1997, 480 pages) Though they seem quite old. Is there anything newer or better? I guess for Linux-specific issues you have to read the docs/source for things like ALSA, Jack, LADSPA/LV2, DSSI & LASH. Damon

[linux-audio-dev] lists.linuxaudio.org migration complete, time to consolidate LAD/LAU/LAA?

by Ivica Ico Bukvic

Greetings all, I am pleased to announce that the consortium lists have been migrated from the agnula domain and are fully functioning. They can be accessed via lists.linuxaudio.org. This important migration will greatly simplify further consolidation of online resources. Given that there was some discussion about this before which has elicited positive feedback, in an effort to consolidate online resources please consider this an open call to LAU/LAD/LAA maintainer(s) to consider migrating lists to the lists.linuxaudio.org. Provided that there is still interest for such a move, the consortium will provide you with necessary help to make migration as seamless as possible. Furthermore, linuxaudio.org in conjunction with Virginia Tech will provide: 1) virtually unlimited bandwidth 2) generous disk space 3) the necessary access to maintainers 4) the assurance that no institutional, logistical, and/or any other kind of control will be exerted over the mailing lists, respective maintainers and subscribers The list of current online resources hosted by linuxaudio.org can be found at portal.linuxaudio.org. I sincerely hope that the community will support this important milestone towards consolidation of Linux audio online resources. Should you happen to have any additional questions and/or concerns, please do not hesitate to contact me. Best wishes, Ivica Ico Bukvic, D.M.A. Linuxaudio.org Director Virginia Tech Department of Music - 0240 Blacksburg, VA 24061 (540) 231-1137 (540) 231-5034 (fax) ico(a)linuxaudio.org http://www.music.vt.edu/people/faculty/bukvic

[linux-audio-dev] alsa mixing

by Milan Mimica

Hello! We're designing a new sound subsystem for allegro game programming library, and we would like to take advantages of multiple hardware voice capabilities. On linux, ALSA is the only software that possibly could expose API for such a capability, is that right? It is possible to open multiple PCM outputs and play sound at the same time on all of them. The problem is that we miss some basic mixing features, like panning a mono sound on multichannel output for example. A similar feature is implemented as 'route' ALSA plug-in that can be specified in .asoundrc file, but it is not flexible enough. So the question is, does ALSA provide such functionality? If not, which library could? Is it possible that linux OS doesn't provide any API to take advantage of such hardware capabilities? -- Milan Mimica http://sparklet.sf.net

[linux-audio-dev] Locks or no locks?

by nick thomas

I apologize if this has been discussed previously on the list; Google didn't seem to be turning anything up from the list archives. I'm writing my first DSP program for JACK. My problem is this: I've got a high-priority audio synthesis thread, and a low-priority user interface thread, and they need to communicate: the UI thread needs to tell the synthesis thread to respond to the user twisting knobs and moving sliders in the interface, and the the synthesis thread needs to tell the UI thread what it's doing, so that the UI thread can update its monitoring widgets. I'm sure that this is an extremely common situation for JACK programs, and I was wondering how to handle it. I know of two possible approaches: using locks and shared memory, or using FIFOs and no shared memory. Vanilla pthreads provides direct support for the former approach, and JACK's ringbuffer interface seems to provide the necessary primitives to implement the latter approach. A lock-based system would probably be substantially simpler to implement than a lock-free one; however, I can imagine some possible priority inversion issues with a lock-based system. I don't know if that is ever a problem in practice, with real-time scheduling enabled. Anyway, there's my question: which approach (lock-based or lock-free) is generally favored for JACK programs? Thanks for helping a newbie out!
