Hello A friend and I have made a VST plugin as a college project, and would like to open source it, and possibly port it to other plugin APIs. We are considering the GNU GPL for our licence, which has lead to this question: Does VST count as a special exception of being "anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable," or should we follow the suggestion about [1]controlled interfaces in the GPL FAQ?

[linux-audio-dev] Intervention schedules

by Juhana Sadeharju

Hello. I found an interesting paper on intervention schedules. The author Curtis Abbott worked at Lucasfilm and the paper is only one of the series of papers written by them. Their system had multiple DSP processors and multiple control computers with automation. We are doing similar real-time system in software. In any case, the paper is at "http://www.funet.fi/~kouhia/abbott-ischedules.tar.gz" for a couple of days only as I'm not the copyright owner. Anyone has the following papers. These are also related to my search on prior-art for so called Gigasampler patent. IMHO, we do not need prior art for caching (and keeping) the first part of each audio clip to memory, but there are people who are willing to weaken their open source software volunteerly. J.M.

[linux-audio-dev] [ANN] QAMix - MIDI controlled Mixer for ALSA

by Matthias Nagorni

Hello, the first version of my new QT based mixer for ALSA is available from: ftp://ftp.suse.com/pub/people/mana/qamix-0.0.1.tar.bz2 The mixer GUI can be configured with an XML description file. Default files are provided with the tarball. See the README for more. At this occasion I would like to also announce QARecord, a simple but multithreaded stereo recording tool for both ALSA and JACK. Version 0.0.9 fixes a bug in the level meters. ftp://ftp.suse.com/pub/people/mana/qarecord-0.0.9.tar.bz2 Have fun !

Sorry to hear about your uncle's accident. -----Original Message----- From: Robert Jonsson [mailto:robert.jonsson@dataductus.se] Sent: Wednesday, June 04, 2003 1:50 AM To: linux-audio-dev(a)music.columbia.edu Subject: Re: [linux-audio-dev] Goodnews Good news.... yeah... sure... When I read the title I was hoping for something like: - Kernel 2.6 is tested reliably with 16-samples buffers... or something similar... :-) Oh well, I'll have to settle for the millions then... /R

Re: [linux-audio-dev] latency and P4 hyperthreading?

by Taybin Rutkin

How does the P4 machine compare against itself with hyperthreading turned off? I'm not surprised that hyperthreading is slower than a true dual CPU setup. Two CPUs sharing their cache? That's got to increase cache misses. Taybin -------Original Message------- From: Fernando Pablo Lopez-Lezcano <nando(a)ccrma.Stanford.EDU> Sent: 06/02/03 09:05 PM To: linux-audio-dev(a)music.columbia.edu Subject: [linux-audio-dev] latency and P4 hyperthreading? > > Hi all, has anyone tested latency on a P4 machine with Hyperthreading support? (HT simulates two processors on one processor using - I guess - the spare time available in the cpu when it is waiting for, for example, memory accesses). Anyway, on a: P4 2.4G 800MHz fsb, 875P chipset, 1G ram, Seagate Barracuda V 60G drive: Booting into an smp kernel with HT enabled in the bios (kernel based on 2.4.21-rc6 with the usual low latency, preemptive and full acpi kernel patches) I see both processors, but the latency in the disk tests (using latencytest 0.42) has spikes that go up to 10/15 msecs, specially in the read/write test. If I boot into a up kernel, or if I boot with acpi=off I see only one processor and the latency for the disk tests is fine. Same kernel, same alsa on a dual Athlon MP 1800+ machine does not show any abnormal latency behavior so this seems to be confined to HT machines... :-( I guess "made up" processors are not as good as real ones :-) -- Fernando >

[linux-audio-dev] MVC again

by Juhana Sadeharju

Hello. It is still quite unclear to me how I actually would code the MVC type software. Can anyone give practical hints? Practical examples taken from existing software would be fine too. What open source software uses MVC? Most open source software seems to manipulate the model data in the GUI routines, I see. MVC sure is a great thing, but I would like to see a concrete toolkit or a hint list which helps me in making perfect MVC code immediately. Is it even possible to write a MVC toolkit? What would be in such a toolkit? Best regards, Juhana
