[linux-audio-user] Muse strange problem with WAV play

by krozilo＠nm.ru

Hi! now i use muse 0.6.2, jack 0.9. i create new wave track, import wav file and try to play. the first time ok, but no sound on other times. when i press stop button during the playing, press <- button (go to start of song) and again press play, then muse play wav-track, but from the point of prev stop, not from the start of the wav-track. midi-tracks work ok. re-importing wav file and re-starting muse hasn't effect. only remove *.wca file. what is my mistake? sorry for my english, regards - Z.

[linux-audio-user] resend: more about sync (was: rosegarden/ardour, ardour/adat, etc.)

by Aaron Trumm

Hi all. I've been trolling and testing various sync methods and I've noticed some questions popping up. Is it just me or is the linux audio situation a bit incomplete at this point with regard to information on that subject? It may just be that most of the programs are still struggling to develope sync techniques (MTC, MMC, ADAT sync, SMPTE, jack transport, etc. etc.), but also is there a relative lack of info/tutorials/etc? The reason I ask, is because not only for my sake, but for the sake of the community, I'd sure be glad to try and make a dent in that, maybe document some toots, or whatnot. of course, this all has to be in sync (no pun intended ;) ) with the development of the capabilities... I wish I had time to sort of type out something more detailed - I'll get to that sometime here (running short on time right this minute :) ) one basic hole I see at least in my understanding, is what the HECK is jack_transport, how does it fit in, etc.? that's ONE - there are lots of holes for me *laugh* another curious one is ecasound? it's the veteren around here in a lot of ways - does it sync to anything? ok well I'll wait for thoughts and then as soon as I can get a chance, I'll write something longer and sort of put out to y'all what I've found out, and see what holes can be filled - cheers (sorry for any unclarity in this email, unclarity is why I'm starting this thread! :) ) - Aaron www.nquit.com

[linux-audio-user] Re:How to change alsa driver

by David Baron

I have a debian/KDE setup using Knoppix. It assigned an incorrect driver to my sound card. Alsa has one (not tested--arg!) that MAY work. How to I make the substitution? Modprobe .... quits with an IRQ conflict as the other driver owns the slot.

[linux-audio-user] adat sync/ardour - resend

by Aaron Trumm

I'm always forgetting bout the plain text/html message thing! hello all! :) thought I'd cross post this note I just sent to ardour-users list: ----------- hello - someone mentioned recently getting ardour to work with ADAT sync - I think it was beta 8 and any alsa 1.0 I can't find the thread - anyway I'm wondering about that - anybody else have success there? I'm trying to do that very thing but I'm not having luck - don't know why yet - I'm trying with: ALSA 1.0blahblah.rc2 ardour 0.9beta9 sound card: RME HDSP 9652 ADAT source is actually an Emu Darwin I set ardour's sync source to "ADAT" in the options window, and expect to be able to play darwin and have ardour pick up, but no suck luck. I don't know if I need to do something else. I also don't know if the sound card's ADAT sync is supposedly working. I read something back in August about the ADAT sync on the 9652 being troublesome... anyone have any thoughts?

Re: [linux-audio-user] JACK session management.

by Taybin Rutkin

qjackctl has had some sort of session management feature in it for a couple releases now. I haven't used it, but it looks workable.

I've done that in the past, but its a bit fiddly and doesnt work well with apps that append thier pid the the jack name - though yan can override than on many. - Steve

[linux-audio-user] Capturing/Recording streaming audio

by roger

I would like to know if there's a tool that will capture/record streaming audio links. An example is "Premiere Radio Networks" -- which appears to simply use windows media player or real audio streams. ie, pipe it to a raw file or something? -- Roger http://www.eskimo.com/~roger/index.html

[linux-audio-user] looking for help with ecamegapedal 0.4.3

by Paul Berry

Hello I have recently compiled and installed ecamegapedal v0.4.3 - [libecasound 2.3.0]. and I'm having some problems getting it to work right. I thought I'd post my questions to this list as I'm assuming Kai Vehmanen subscribes to this list as well. First off, ecamegapedal is exactly what I am looking for - an easy way to turn a computer into an effects box. Realtime reverb, delay, LAPSPA plugins... Perfect. My two problems: First is that I'm getting a lot of backround distortion/ static. I can hear my input signal fine and the selected effects work as they should. The level meters are quite active when there is no signal input/ quiet passage and the distortion is a low level buzzing/ static that is totally related to running the program. The other problem is periodically the computer totally locks up, GUI, mouse, keyboard, everything freezes and I have to do a hard reset (no other program that I've run seems to cause this on my computer but the computer is old and flakey in other respects...). I have tried: Running as root- a little less distortion but not much difference. Adding "default-audio-format=s16_le,2,22050,i" to my ~/.ecasound/ecasoundrc file. This doesn't seem to change the static problem. Anyway, be great if it worked better, thought I'd ask... Thanks for any input, Paul Software details: libecasound 2.3.0 gcc (GCC) 3.2 20020903 (Red Hat Linux 8.0 3.2-7) redhat 8.0, 2.4.18-14 kernel with ALSA 0.9.8 drivers jack-audio-connection-kit-0.80.0 installed but not used qt-3.0.5 installed kernel is not low-latency (that I know of) Hardware details: Intel Pentium pro 200MHz, i440FX chipset 256MB RAM Creative SB AWE64 ISA soundcard signal source is an amplified microphone going into the line input of the sound card

[linux-audio-user] Cooledit substitutes?

by r7

Hi people Apologies for interrupting with a rather basic question. I'm a new subscriber with a fondness for Cooledit. I'm not currently a Linux user but am considering getting a new ibook and installing linux on that. However I was wondering if anyone could suggest an editor/multitrack with a similar interface with Cooledit to ease the transition woes. I found Audacity (the PC version) a little difficult to maneouvre for my purposes. My current working method involves using several large audio files (say 10-20 min each) and many more smaller ones which I then splice into smaller sections (anything from 1 second to 3 mins).I then rearrange these sections in the multitrack screen. Someone suggested Sweep in the archives. Is there anything else anyone would suggest to minimise the transition pain? Any help much appreciated! Thanks in advance. aaron __________________________________ Do you Yahoo!? New Yahoo! Photos - easier uploading and sharing. http://photos.yahoo.com/

[linux-audio-user] Re: Syncing Ardour and Rosegarden (or Muse)

I assume that's still the case since after fixing one of my problems I tried to use it as a transport slave in Ardour and no joy. I can't get muse to actually produce noise yet, so I can't comment on it. HTH David
