Umm, actually I'd heard nearly the exact opposite opinion voiced on more than one occasion, namely, that higher-sample rates are basically an audio industry ploy to sucker rich yuppies wth $5000 USD power amps into buying "Sgt. Pepper" and "Are You Experienced" in yet another format. Personally, I'm inclined to believe that, and I do consider myself an audiofile. FWIW, I also run everything, even the DAT machine (yes, I've still got one) at 44.1, even though my Delta can handle 96, because I really don't like to deal with resampling, and nothing I'm doing at this point has any likelihood of ending up on DVD-A anytime soon.

[linux-audio-dev] [ANN] QJackConnect 0.0.1

by Dr. Matthias Nagorni

Hi, QJackConnect 0.0.1, a QT based patchbay for JACK, is available from http://www.suse.de/~mana/jack.html or ftp://ftp.suse.com/pub/people/mana/qjackconnect-0.0.1.tar.bz2 This is the first official release (some pre releases have been already in use, but they were based on a bad hack) and its published under GPL. Thanks to Kai Vehmanen for sending a patch which adapts QJackConnect to the current CVS of JACK and finally resolves the bad hack. I also wrote a small FM synthesizer which is both a (minimal) client to JACK and the ALSA sequenzer system. jack_miniFMsynth.c is available from the QJackConnect webpage as well. Have fun !

If I have the time (in a week or so) I'll have ago. It'd be nice to have as a ladspa plugin but to do the gui justice it might also need to be a jack client? jake. > -----Original Message----- > From: Paul Davis [mailto:paul@linuxaudiosystems.com] > Sent: Tuesday, 5 November 2002 8:43 AM > To: linux-audio-dev(a)music.columbia.edu > Subject: [linux-audio-dev] anyone interested in porting a GPL'ed VST > plugin? > > > it shouldn't be *too* difficult ... > > ------- Forwarded Message > > Date: Mon, 04 Nov 2002 20:41:11 +0100 > From: "Philipp Mott" <pmott(a)lisa.de> > To: <vst-plugins(a)lists.steinberg.net> (VST PlugIns) > Subject: [vst-plugins] Rumpelrausch free source code release > > Hi everyone, > > I finally decided to release one of my plugins as open source. > You can use the sources of ZR-3 under the restrictions of the > GNU Public Licens > e. > And you can (please) donate, if you like.

[linux-audio-dev] amp modelling

There's a good chance I could get my hands on a Behringer V Amp 2 for as long as I need it. If I did, I'd be able to run whatever signal I liked through it and try different amp/speaker settings, different gain levels, etc. and produce a lot of data that would hopefully be of use in trying to produce some sort of "amp modelling" ladspa plugin. I'm open to suggestions as to what would be the most useful things to measure, and what to vary across measurements. My first thoughts were: - a range of pure tones, say starting at 440Hz and going up 3 octaves, - ~5 gain levels, - ~5 amp/speaker simulations, That'd give us 100 "data points" to work with when it comes to testing our models. Comments anybody? Stuart

[linux-audio-dev] Help on threads needed

by Dave Griffiths

Hi all, I'm just trying to tweak SpiralSynthModular's threads to be a bit more efficient, and I can't seem to find much info regarding thread priorities and such. I have two threads, a GUI one and an audio one. I can hand the audio thread over to Jack which works fine, but I'd also like to be able to run ssm in normal user mode and standalone without jack. I think I have two questions: 1. Is there any way to prioritise the threads running as a normal user (SHED_OTHER) my man pages suggest not, which is quite annoying. Should I "nice" the GUI thread down in priority? 2. What is the correct setup for SHED_FIFO? What priorities should I run the audio and GUI threads at, and should the GUI thread use SHED_FIFO too? Thanks for putting up with my ignorance :) Dave : www.pawfal.org :

How did this end up here? Anyway based on the discussion had so far in this thread I have updated the JACK user Howto to be more precise and yet somehow broader and muddier at the same time :) -- Patrick Shirkey - Boost Hardware Ltd.

I think it would be best to have this info in the alsa-docs. Here's what I consider still needed to make the alsa-docs complete: - A paragraph on using alsaconf. - Anything that is distro specific. Although it might be better to make a page for this which people can add notes to. - Any info on using the controls for cards that have them. Specifically adat, wordclock, optical. I would like to have a section in the template for this but don't have any cards that use these so cannot test myself. -- Patrick Shirkey - Boost Hardware Ltd.

People who are into this topic might want to take a few minutes to review Appendix C.1 (pp 66-70) of the MWPP draft: http://www.cs.berkeley.edu/~lazzaro/sa/pubs/txt/current-mwpp.txt It basically describes the three methods MWPP provides for coding timestamps onto MIDI commands when packetizing a MIDI stream. The goal is that whatever your MIDI source is (a MIDI 1.0 DIN jack, an algorithmic composition program, etc), one of these three methods will be the right one to capture the timing as best as can be, into an RTP packet. Feedback is welcome on the topic, we're starting to close in "Last Call" for the document, but there is still a few months left ... ------------------------------------------------------------------------- John Lazzaro -- Research Specialist -- CS Division -- EECS -- UC Berkeley lazzaro [at] cs [dot] berkeley [dot] edu www.cs.berkeley.edu/~lazzaro -------------------------------------------------------------------------
