[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

[linux-audio-dev] Radium V0.62alpha for linux.

by Kjetil S. Matheussen

***** This is an extremely informal release. The program is not useful yet for linux, but the porting is nearly there. So for anyone interested in looking at, in my opinion, the best :) graphical note-based music editor for any plattform, running in linux, here is a .tar.bz2 file: http://www.notam02.no/radium/bin/radium062_src.tar.bz2 ***** To make it run, cut and paste the following into a terminal: wget http://www.notam02.no/radium/bin/radium062_src.tar.bz2 bzip2 -d radium062_src.tar.bz2 tar xvf radium062_src.tar cd radium062_src cd radium ; ./build.sh cd .. ; make ./start.sh ***** Here is the homepage: http://www.notam02.no/radium/ ***** And here is a screenshot of 0.62 running in linux: http://www.notam02.no/radium/pictures/v062_linux.png (notice the runnning of xlib(editor), qt(fx selector), gtk(midi settings/help) and tk(playlist) simultaniously :)) --

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

by Fernando Pablo Lopez-Lezcano

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] Presentation & New project.

by ListBox

Hi to everybody... I'd like to introduce myself to you and to present you my new project. I'm a 26 year old programmer living on the Canary Islands. Unfortunately I'm new to Linux and I've been specializing on Pascar rather than on C. I'm a hobby musician and that's where my idea started. I seek people like me who'd like to help me to assemble a really good studio system with existing aAPIs and peaces of code. Today I uploaded my initial page which explains the project. Please have a look at http://laudio.freehomepage.com/index.html (my page) where I describe the project in detail. Comments are welcome. Thank you & greetz Merlin

[linux-audio-dev] A "best" event delegation strategy?

by Lukas Degener

Hi list, Here is a propblem that is propably already solved in another context, so i would like to know some opinions on it: I am trying to implement a (hopefully:-) ) simple general-purpose event delegation architecture. The actual application will propably be something like a network of modules that can do arbitrary filtering, generation and manipulation of midi events in real time. As propably different kinds of external event sources, like several midi ports, maybe joystick device and of course a gui, are involved, how would one efficiently organize the delegation of events passed between the modules, so that the everything is still thread-safe? The three main ideas i can currently think of are: A: don't do it at all, that is, everything is implemented as simple subject/observer patterns, so that the communication is a pure module-to-module thing. Mutexes et al, would have to be managed by each individual plugin. B: use a global, mutexed event queue. This could be a priority queue for time-stamped events, or a simple FIFO. C: use local queues. As above, but for each individual module. Each of the above aproaches seems to have its advantages and disatvantages. E.g. if queues are used, this would as far as i an judge, make it easy to have feedback cycles. OTOH this would propably introduce some overhead which aproach A wouldn't have. C would propably involve a single thread for each module, or a global "clock" thread that periodicaly calls an "process_queue" method on each module. Is there a general "best" way to do this? Kind regards, Lukas

[linux-audio-dev] [ANN] swh-plugins 0.4.2

by Steve Harris

http://plugin.org.uk/releases/0.4.2/ Highly recomended upgrade for 0.4.x users. Changes: * Great new set of filter plugins from Alexander Ehlert * Applied patch from Anand Kumria to make it build with gcc 3.3 * Rewrote the flanger modulation code - its not optimised, but should work * Added support for FFTW3 * Added denormal killer to l/c/r delay - hopefully works better on PIV * Fixed serious peak detection bug in lookahead limiter * Things I forgot Thanks to Nick T. and Anand K. for bug reports and Alexander E. for the new plugins. FFTW3 is much better than old versions, but if youre going to upgrade make sure you tell it to build the 32bit library, and optimise it right for your CPU. The SIMD optimisations (SSE etc.) make a lot of difference. FFTW2 will be supported for the near future anyway. - Steve
