[linux-audio-dev] MWPP implementation guide ...

by John Lazzaro

Hi everyone, Just sent off the first draft of the "Implementation Guide" for MWPP, in time for the deadline for the next IETF meeting. You can download it as: http://www.cs.berkeley.edu/~lazzaro/sa/pubs/txt/current-guide.txt See below for the abstract. A few sections in the main body, as well as the Appendices, remain to be written, but I decided to send it off because the completed parts are in pretty good shape, and early feedback on the direction the document is taking (as the non-normative companion to the main MWPP document) would be helpful. The current plan is to make some minor changes to the normative MWPP document, in response to comments received since its September 22 submission, and resubmit it in time for the meeting deadline for updated documents. So if you're holding onto any comments on this document, now is a good time to send them along -- this document can be downloaded as: http://www.cs.berkeley.edu/~lazzaro/sa/pubs/txt/current-mwpp.txt --- INTERNET-DRAFT John Lazzaro October 27, 2002 John Wawrzynek Expires: April 27, 2003 UC Berkeley An Implementation Guide to the MIDI Wire Protocol Packetization (MWPP) <draft-lazzaro-avt-mwpp-coding-guidelines-00.txt> Abstract This memo offers non-normative implementation guidance for the MIDI Wire Protocol Packetization (MWPP), an RTP packetization for the MIDI command language. The memo provides a detailed description of a sample MWPP application: an interactive MIDI session between two parties that send and receive RTP and RTCP flows over unicast UDP transport. The Appendices focus on special issues that arise in other types of applications: content-streaming applications, multi- party applications, applications that use reliable transport such as TCP, applications that do not use RTCP, and applications that send several MWPP RTP streams in a single session. ------------------------------------------------------------------------- John Lazzaro -- Research Specialist -- CS Division -- EECS -- UC Berkeley lazzaro [at] cs [dot] berkeley [dot] edu www.cs.berkeley.edu/~lazzaro -------------------------------------------------------------------------

It is becoming more of a community property these days. Does anyone else have any suggestions. Keeping in mind that the site is primarily for new users most of whom expect a graphically dense site at least until they get into the Linux way. -- Patrick Shirkey - Boost Hardware Ltd.

Hello. Does anybody of you know where I can find an updated version of the lowlatency patch for 2.4.20-pre ? I already tried to make it apply but due to massive reiserfs changes I backed it out for now... *Kristian :...

It's about due for a redo anyway. The info is still pretty vital. Notice that there have been almost no questions about how fast Linux latency is since it was put up. That's true the link is out of date. But it's the only page I know of which has so much information on the low latency patch. I can't force Benno to do the work that he has stated would be done. >The logos along the top are all in clashing styles and many of them are >aliased.

[linux-audio-dev] posix clocks

by Bob Ham

Hi all, I just read this in the latest kernel traffic: "George Anzinger announced: This, patch implements the POSIX clocks and timers functions. The two standard clocks are defined(CLOCK_REALTIME & CLOCK_MONOTONIC)." I've got a feeling 2.6 is going to be very good for l-a-d :) Bob

[linux-audio-dev] Open Music

by David Gerard Matthews

Is anyone working on this: http://www.ircam.fr/equipes/repmus/OpenMusic? Apparently they GPL'd the sources, and you can download it, but it's written in Lisp, and MCL PPC Lisp at that. However, as they put it: "At the beginning, this will make sense only to people owning the Digitool compiler. Although we are conscious that this limitation does not fit clearly into the GPL framework, we think that making the sources available is an oppurtunity to raise collaborations leading to new versions of OM that would depend only on open sources compiler, particularly on linux platforms" I did speak with some Ircam people at Darmstadt this past summer, and I don't think they really have the interest in doing the port themselves. However, Ircam certainly isn't anti-Linux, so they might be able/willing to help/be persuaded to work on it. (François, and Norbert, if you're on this list, feel free to comment.) -dgm

[linux-audio-dev] Wave Editors

by Lea Anthony

I'm trying to get a picture in my mind as to what is out there. Could someone please give me a list of Wave editors that are seen as potentially really good under Linux? Cheers, -Lea.

[linux-audio-dev] Meterbridge 0.0.6

by Steve Harris

http://plugin.org.uk/meterbridge/ Added a correlation meter to the JellyFish, thanks to Ari Kauppi for pointing me to the maths. Its calculated using the non-parametric correlation function Tau, incase anyone cares. Changed the default meter type to PPM. Also added a simple osciloscope display. Hopefully this will be the last release for a while (unless there are any bugfixes). - Steve
