Re: [linux-audio-user] what window manager are you using?

by Austin

During latency-critical production, I've been using the Matchbox Desktop. It is super-light, but still full-featured (snazzy desktop and menu, Pango, GConf2, image viewer, video player) and fully graphical. Actually, the graphics are far nicer than IceWM or Fluxbox IMHO. http://matchbox.handhelds.org/ I have added it to Mandrakelinux 10.1 by the way. Austin

Re: [linux-audio-user] M-Audio Delta 1010LT .asoundrc?

by jmacdermott＠ns2.i-mecca.net

Thanks for the suggestion, Russell. I will keep it in mind when I try Jan's suggestion. Crossing my fingers...!

Re: [linux-audio-user] what window manager are you using?

by Stephen Hassard

If you don't need module support, you can compile a completely static kernel with just the drivers/opts you need. I find that my custom kernels take about half the time to boot that the standard distro ones do. During runtime, they tend to run more or less the same if you're running similar kernels. A lot of distros and many custom patches, so you may find that things feel a little faster or slower.

[linux-audio-user] [ANN] Mammut V0.17

by Kjetil Svalastog Matheussen

http://www.notam02.no/arkiv/src/ Mammut will FFT your sound in one single gigantic analysis (no windows). These spectral data, where the development in time is incorporated in mysterious ways, may then be transformed by different algorithms prior to resynthesis. An interesting aspect of Mammut is its completely non-intuitive sound transformation approach. This is very minor update. If you already have mammut, theres probably not much point in upgrading. The "big" change in this release is the first entry in the changelog. I must also warn that mammut can be a bit hard to compile up, now that pygtk1 has been replaced with pygtk2 in all recent distributions I know about. 0.16 -> 0.17 -Initialize sound at startup, so that mammut appears in jack patch bays. -Removed the included sndlib binary. -Added a point in the INSTALL file about how to configure mammut to find the pygtk1 files. -Added a note in the INSTALL file about that sndlib for some reason does not work with delta cards when using the alsa driver. The oss driver (under alsa emulation), and the jack driver works just fine. --

[linux-audio-user] Re: Best distro for Audio??

by Juhana Sadeharju

It is likely that audio and video professionals need later more disks. But RedHat has only a cumbersome, lowest level fdisk. However, RH has a good graphical disk formatter but it is available only when RH is installed first time. Now that USB disks are very easy to add by users, should distros have such easy-to-use partitioner and formatter. Have Debian and other distributions a good graphical disk partitioner and formatter? In the application launcher menu? Juhana -- http://music.columbia.edu/mailman/listinfo/linux-graphics-dev for developers of open source graphics software

[linux-audio-user] Stompboxes2 and such.

by Lauro Costa G. Borges

Hi, I don't have a guitar yet, so I cannot do this, I would like to hear samples played with stompboxes2, so I can decide if I am going to get one now or wait until I can buy a guitar and an amp. My lazy friends refuse to install stompboxes2 and try it for me, so.. I could not find messages about that on the archives. I thank you if any of you ppl can show me links of where to download your samples, also telling me with which guitar and soundcard you used to play these samples (if it's hardcore --> =). Does a cheap soundcard matter so much if and I am going to play just for fun and for me on my bedroom!? It's full duplex, if that matters too. Oh, and if you could share your experiencies with gnuitar and creox =). Thanks in advance, Lauro C. ===== - amo ergo sum _______________________________________________________ Yahoo!

[linux-audio-user] Re: low tatency

by Ben

There was an article a few months back in Linux Journal that described how to "lock" a thread onto a processor (and disallow any other threads form running on that processor). If you were to lock the JACK process into a single processor on an SMP box, wouldn't you effectively get very low latency without any kernel patching or anything? You'd have to use lock-free-fifo's to talk to the other processor (which is running the UI, etc) of course. And you'd use a polling model to read/ write data to the soundcard. Does ALSA have it's own thread in addition to the JACK thread, and would it have to be on the same processor? I'm not a Linux/Intel architecture guru, so forgive me if I've missed some obvious points. -Ben

[linux-audio-user] OT: SourceForge mail server being temprimental for anybody else?

by Luke Yelavich

Hi all I was just trying to post an email to the MusE developer list, and the SF mail server said that it wouldn't accept it. So I try to re-subscribe, several times, and failing each time, stating that my domain didn't have a postmaster address. I finally tried again, and it worked. Has anybody had any problems like this, or should I be trying to find out whether anything funny is going on at my webhost? -- Luke Yelavich http://www.audioslack.com luke(a)audioslack.com

This morning I tried starting muse from a term window after starting timidity -iA As soon as I try to import a midi file, the muse display starts to lose all its buttons and the menus don't respond and all the areas of the window turn into useless blocks of nonresponsive vague colored areas-- you know the look. I checked the term window for messages and saw only: open projectfile: No such file or directory no JACK audio server found NO Config File </root/.MusE> ALSA: samplerate 44100 not available, using 44099 cca_open_socket: could not connect to host 'localhost', service '14541' cca_init: could not connect to server 'localhost' - disabling ladcca After killing it, I decided to try at least 'touch /root/.MusE' knowing that an empty config file really wasn't going to do the trick, but I thought maybe if there was somewhere for Muse to starting recording settings, that seemed as good as anything. At one point this morning I *did* succeed in getting muse to load the midi file without crashing, even though I still heard nothing. (yes, I've checked my mixer settings--no channels muted, and everything at least at non-zero). This "success" came after messing around with what I think is qjackctl, trying to hook up the ens1371 in the left column with one of the timidity ports in the right column. When I pressed the play button in muse, I could see all these bars for each track moving around, but no sound. Hey, it least it didn't crash utterly that time! I feel like I'm getting warmer somehow... -Mark ===== -- Seek professional help! Ask a librarian. __________________________________ Do you Yahoo!? Yahoo!

[linux-audio-user] dipping toes in 2.6 waters

by Florin Andrei

I've not been able to follow LKML too closely in the last few weeks, so i'm out of loop with the recent developments. If some of you folks did watch it, do you care to bring the rest of us up to speed WRT the latest 2.6 developments that are related to "audio" kernels? The issues i'm interested in are: 1. "Classic" pre-emptability. Why Con Kolivas recommends against enabling preempt in vanilla 2.6, and (if it was a valid recommendation) whether that is still an issue 2. The Ingo Molnar voluntary preempt patches. Are they ready yet, yes/no? With or without -mm? 3. Staircase scheduler, either as a standalone thing or incorporated in the latest -mm patch. Better than vanilla for audio, yes/no? 4. Combinations of the above. Is the classic preemt compatible with the rest? Anyone using the "vanilla preempt + Ingo Molnar patches + Andrew Morton series + staircase" supercombo? -- Florin Andrei http://florin.myip.org/
