Hi, 1. Can anybody explain me (I think, Fons Adriaensen can :-) the JAAA "Bandw" parameter meaning? 2. When Bandw parameter is rather small, I see two spectrums - main (blue) and, below the first, - the second one (gray). What is the last spectre spectrum meaning? Andrew

[linux-audio-dev] jack, low latency and IO

by Artem Baguinski

I'm a bit puzzled with this one thing about low latency and jack: real time bits can't do IO, but don't you get latency between say me pressing some button and sound doing click? there's no garanty the not realtime part of the application will run often enough to read the input device, no? just recently some heavy process started when i was fulling around with some soft synths [i know that shouldn't be happening, but i just recently switched distros and I haven't learned enough to write dont-bother-me script to switch all potential sources of disturbance] and the GUI of the soft synth became quite irresponsive, while audio went on without any glitches - that's I suppose because the audio part was running in realtime thread and decided itself when to yield cpu. is the only way to ensure the effects don't lag from control input to make sure I run as little processes as possible and hope the input thread will be scheduled often enough? -- Artem Baguinski: http://www.artm.org/ V2_Lab: http://lab.v2.nl/ V2_ Organisation for the Unstable Media: http://www.v2.nl/

[linux-audio-dev] Patents on some Linux OS code

by Cornell III, Howard M

All, The 11/22 issue of Computerworld has a blurb about Microsoft CEO Steve Ballmer warning government leaders in Singapore that switching their 20,000 PCs from Windows to Linux could subject them to patent lawsuits. I have heard some tales about commercial versions of Linux including indemnification of users against these suits. What is the current status of the patent issues? Will they ever be resolved, or are all Linux users susceptible (proportional to the depth of their pockets)? Howard Cornell

[linux-audio-dev] ssm2

by Dave Griffiths

Hi all, Just a quick note that we are currently considering starting a new version of spiralsynthmodular from scratch (well almost) that will at first take the form of a osc server/jack client that will load and connect ladspa plugins together. Just wondering if anyone has an idea of an osc protocol for building modular synths in this manner (thinking supercollider) and if we should use something approaching a standard syntax of osc messages... this would mean that work such as graphical user interfaces could be shared, etc... Or has some or all this stuff already been done? Most of the work will be in converting ssm's 50+ existing plugins to ladspa - and writing a gui that sends osc messages. My main motivation at this point is to just have a lightweight scriptable non-gui jack ladspa modular effects rack for live performance use, should I just use ecasound? cheers, dave

You may argue that I suffer >from over-exposition to commercial environments; I concur. :) Dattorro's plate reverb of Griesinger type also feeds the M = L+R signal to the main reverberator. However, that may not be a good idea if L and R will sound bad when summed. When summing is done that way, only the bad signal is going on inside the reverb. Nothing turns it good.

[linux-audio-dev] TAKE ACTION - RME customers and linux audio users please read

by Marek Peteraj

Hi all, following the conclusion of a very long discussion on both LAD and LAU mailinglists, i would like to invite you all to participate in an event that should take place on RME's official forum. The goal is to run a thread on linux audio and RME support. Not a discussion, but rather just raising your hand if you are a customer and letting them know what hardware you are using, or whether you are interested in their products or plan to purchase one if you are not a customer of RME todate. Please, if you are a RME customer, let them at least know what hardware you are using. You are free to express your feelings and you are free to express no feelings if you do not wish. Please avoid using swearwords. In case you haven't found the thread, feel free to start it. "Hi, i'm a linux audio user and i'm using your prod. X with linux audio and i plan to continue using your products in the future (upgrades, new products) if there will be future support from RME by providing specifications" or something along these lines. We need to agree on the topic so that people can easily find it: "Linux audio, ALSA and RME support" In case you are not satisfied with the topic, let us know so that we can agree upon another one. Please be sure to post in that thread. In case you have friends that use linux audio with RME and are not LAD or LAU subscribers, please let them know. The forum can be found here: News server: news.x-networks.de Forum: rme-audio.forum In case you have troubles finding the right software in order to reach the forum, here are some suggestions: Mozilla www.mozilla.org Pan http://pan.rebelbase.com/ Pine http://www.washington.edu/pine/ In case somebody knows of other newsreader software please let us know. Ok, let's go! :) thanks Marek

[linux-audio-dev] ladspa 2 idea

by Taybin Rutkin

I don't know if this is completely dead or just a little dead but I had an idea today. It'd be kinda neat if there was a mechanism for grouping related control ports together in the UI. Taybin
