[linux-audio-user] sticky windows [may be OT]

by "horsh

Hi, dealing with linux GUI audio applications I have found that the following feature would be usefull: I want to stick or glue some windows of *different* applications together so that they be organized in "solid body" i.e. so that I could minimize/restore, move them together. (you can find an example of similar behavior in how xmms organizes its subwindows) I know that some window managers offer "border gravity" and some others offer virtual desktops, but sometimes it's just not enough. As fas as I can tell the linux audio goes the unix way in the sence that there are many small interacting programs each doing its own thing. So one needs to have *many* small GUI apps open at the same time. And the feature Im talking about would be realy usefull. So my question is: Which window manager support such "sticky" feature? horsh

Basically this is correct. You didn't give full portnames, though. First you need to find out the correct input ports with "aconnect -i" $ aconnect -i client 0: 'System' [type=kernel] 0 'Timer ' 1 'Announce ' client 64: 'Rawmidi 0 - M Audio Audiophile 24/96 MPU-401' [type=kernel] 0 'M Audio Audiophile 24/96 MPU-401' .... and then the output ports with "aconnect -o". Your FM synth should show up here. On my box it looks like this: $ aconnect -o client 64: 'Rawmidi 0 - M Audio Audiophile 24/96 MPU-401' [type=kernel] 0 'M Audio Audiophile 24/96 MPU-401' .... client 73: 'Emu10k1 WaveTable' [type=kernel] 0 'Emu10k1 Port 0 ' 1 'Emu10k1 Port 1 ' 2 'Emu10k1 Port 2 ' 3 'Emu10k1 Port 3 ' .... Now I can route input coming from 64:0 to output 73:0 to use a keyboard with the SBLive hardware synth with "aconnect 64:0 73:0". If you use an ALSA sequencer enabled software like Muse or RG4 you shouldn't need to fuss with aconnect, BTW. Just configure it inside Muse or RG4. ciao -- Frank Barknecht _ ______footils.org__ --------- Well, Muse doesn't work because my jack server seems to be the wrong version (libjack), and I did not recompile it yet ( I use Debian unstable ); Could you give me a link to the mentioned "RG4" ( never heard of it before ;) ) Retzki __________________________________________________ Verpassen Sie keine eBay-Auktion und bieten Sie bequem und schnell über das Telefon mit http://www.telefonbieten.de Ihre eMails auf dem Handy lesen - ohne Zeitverlust - 24h/Tag eMail, FAX, SMS, VoiceMail mit http://www.directbox.com

[linux-audio-user] Reliable A/D with linux laptop

by Nathaniel Gray

Hi folks, I've been trying for months now to get arecord to work with the built-in microphone and/or mic jack of my laptop but it just won't work. Since the alsa developers seem totally uninterested in fixing or even understanding this problem (yes, I've posted on alsa-devel many many times) and the built-in A/D on the laptop is unlikely to be any good anyhow I've decided to investigate an external A/D system. It's for a laptop so it would have to be either PC card, USB, or firewire, not PCI. Compatability and reliability are a big deal to me -- I'm fed up with sending mail to alsa-devel, which seems to route to /dev/null as far as I can tell. Can anybody recommend a solution that's really simple to set up and reliable to use under linux and doesn't cost an arm and a leg (e.g. less than $400)? I'm not too picky about number of ins and outs or fancy features, more picky about quality, compatability, ease-of-use, and reliability. Thanks, -n8 -- >>>-- Nathaniel Gray -- Caltech Computer Science ------> >>>-- Mojave Project -- http://mojave.cs.caltech.edu -->

Hmm. How are you measuring latency? I'm not sure how to do it (sufficiently accurately). I'm running SuSE 8.2, which some have suggested includes the low-latency patch, but I don't think so. I've been too busy (lazy?) to check or implement. I find even when playing some .ogg file to jam along with, that hiccups are "disturbing" or distracting. Maybe I've got problems (as a musician wannabe) with my timing? I've got my .ogg files on a server, but I believe xmms pre-buffers (I recall setting it to 1/2 second at one point?) its compressed audio stream, so I think I'm only hearing jitter from variable interrupt response (and temporarily blocked interrupts?)? Your other comment (in another post) about "real life lost packets" (UDP comparison) is interesting. You would have to transmit a time code in each packet, so the player can continually "re-sync" the audio. I don't think the current audio streams do that? I think they "assume" (Benny Hill?) that the audio stream is continuous, and therefore you can derive the timing? -- Juhan Leemet Logicognosis, Inc.

[linux-audio-user] more about HDSP 9652/jack/ardour/hdspmixer

by Aaron Trumm

Hello again - I hope this is the right list for this topic (so far I can only get subscribed to two and I keep bouncing back and forth between them...) first off, may I say thank you to the list members for bearing me, and extra thank you still to those who take the time to respond - amazing gentlemen and ladies you all are; I realize I have written what amounts to several novels worth of emails in the past couple weeks! :) well I started a couple threads earlier about strangeness (or what I think was strangeness) with compiling and installing hdspmixer and such...the questions I had I didn't figure out, but somehow hdspmixer was able to run - whether it's ACTUALLY working, I don't know for sure sure... THAT having been said, I only know of a couple people who are using the HDSP 9652, along with a couple who've developed for it - Mark K, Thomas, Kevin, et al - does any of this sound familiar? : -- a) I've been doing a lot of back and forth and reading but I'm a bit confused as to what hdspmixer is DOING (which makes it harder to tell if it's working :) ) b) my goal, as I may have said on other threads, is to be running ardour with my HDSP 9652, sending each of 24 individual adat optical channels out to 1 channel input in my behringer ddx3216 (outfitted with adat i/o). An earlier thread I started was solved by me adding -d hw:0 to my jackd command line (duh), where I wasn't seeing 24 (actually 26) possible outputs when I clicked on "output" in the mixer in ardour now I'm able to see the outputs, and assign them as they should be, meanwhile in hdspmixer i've picked the preset which assigns ins, out and "playback" (what would be the difference between "out" and "playback" I wonder) to adat outputs, etc: -- first I used hdspconf to change the HDSP to 44.1 for purposes of these tests next I ran hdspmixer I kept hdspmixer running, then started jack from a terminal using: su jackd -R -d alsa -d hw:0 -r 44100 -p 2048 then started ardour from a terminal: su ardour -n <--- that's so no splash screen will appear but what was showing up at the board wasn't what I was expecting *laugh* if I routed a track to channel 1, then it showd up a 3 db too quiet at channel 1 on the mixer, and at the right volume on channel 2 (I was using a -12 1khz test tone that I generated with the board and was able to record to ardour - ardour indeed is playing it at -12.1 - I think the point 1 is explanable but I'll skip that 'cause it doesn't matter just now) if I routed the track to channel 2, it didn't show up anywhere. odd numbered tracks after that seemed to be showing up on 1-2 just like 1 did (although I can't confirm the consistancy of this) I experimented with opening up qjackconnect, which was the only one of the many patch bay programs from planet that showed 24 capture and playback channels and connecting captures to playbacks. this didn't seem to do anything, which made me wonder just what qjackconnect was for. then I closed all, closed the hdspmixer program, and started just jack and ardour. the results from that are: routed to channel 1, it shows up at channel 1, 3 db quiet, channels 3, 7, 9, 11, 17, 19 and 23 at 30 db quiet and channels 5, 13 and 21 at 12 dbs quiet - wha? routed to channel 2, it shows up only at channel 2! 3 dbs under - actually, this 3 dbs may be a non-problem issue in the board, so possibly it can be ignored routed to channel 3, it shows up on 1, 2, 3 and 4 and some other channels at half volume - wha wha? channel 4, nothing channel 5 --> 4, 5, 6 and others ok you get the picture. randomness. a weird mess. I don't know if this is a driver problem, a HDSP 9652/alsa driver patch problem, an hdspmixer problem (I did, as I mentioned, have oddities on compiling that program), a jack issue, an alsa issue, a bug in ardour, a bug in alsa drivers, etc. etc. etc. I only know of a couple people who are using the HDSP 9652 - Mark K, does any of this sound familiar? clearly there are thousands of details - anyone who wants to talk about this and wants other info, as usual, ask and ye shall receive :) (although in some cases, a request for details may yield first the question "how do I find that?" :) ) thanks and I hope this is interesting and stimulating, maybe even educational!!! :) -- -------------- Aaron Trumm NQuit www.nquit.com --------------

[linux-audio-user] jaming over the internet?

by Robert Jonsson

Hi, Anybody know of an application that allows streaming of midi and/or audio over the net for the purpose of allowing several people to jam together? I seem to remember having heard of some such app for windows ages ago... but that doesn't count does it? ;) /Robert

[linux-audio-user] Weird glitchy noise in Mozilla

by Mark Knecht

Hi, I run across this problem a lot in Linux. Maybe someone can help me make my Gentoo system do audio better. All the straight Alsa stuff works well. However, when I'm browsing around I come to web sites that probably want to play some audio, but this is Linux and Alsa, so things don't work easily. At the web site http://www.skale.org I start getting this repeating glitch noise every 8 seconds or so. It hasn't happened every time I've visited the site today, but it's happened a lot of times. In hdspmixer I see this glitch on all 26 playback channels, by the way, so I'm assuming that this means it's some sort of OSS problem, but I'm not sure. What's wrong with my setup of Alsa, which in most other ways works just fine, and why can I also not get mp3 (well, really xmms) to work under Linux? BTW - much non-Alsa audio from Games works fine, but also drives all 26 playback channels. Should it really work this way? Thanks, Mark

[linux-audio-user] Compiling Audacity

by Anahata

Let me first say I'm not terribly used to compiling Linux apps. I usually intall Debian packages with apt-get. So I'm probably making a very simple error, but I'm asking here because someone else might well have built Audacity from source. So here's the problem: Whe I try compile Audacity 1.2 beta, I get screefuls of messages like this: libaudacity.a(PCMAliasBlockFile.o): In function `PCMAliasBlockFile::BuildFromXML(wxString, char const **)': /usr/include/wx/filename.h:100: undefined reference to `wxFileName::Assign(wxFileName const &)' /usr/include/wx/filename.h:100: undefined reference to `wxArrayString::~wxArrayString(void)' The system is Debian, mostly stable but I've installed quite a few bits and pieces from testing. In response to earlier problems with config and compilation I installed: libwxbase2.4-dev wxwin2.4-headers libwxgtk2.4 zlib1g-dev libwxgtk2.4-dev But I can't see what's missing now and I don't understand enough about the error messages, not being intimately falmiliare with libwx (it must have something to do with that) Any ideas, please? -- Anahata anahata(a)treewind.co.uk -+- http://www.treewind.co.uk Home: 01638 720444 Mob: 07976 263827
