[linux-audio-user] Should Stereo to MS then MS to Stereo be a no-op (identity)

by Steve Fosdick

I just tried taking a stereo track in ardour that was recorded with a X/Y pair and add two pugins to the track: a Stereo to Mid-Side(MS) matrix and a Mid-Side to Stereo matrix. The idea was that the MS to Stereo matrix gives me a nice simple control to control the width of the stereo image. What I discovered, to my surprise, was that with the width set to 2.0, the widest setting, the stereo image was still narrower than with the pair of plugins bypassed. Can anyone think why this should be? Steve

[linux-audio-user] alsa: weak recording signal on Suse9.1

by Hartmut Gehrke-Tschudi

Hi, Since I upgraded from Suse 8.2 to Suse 9.1, I get a very weak recording signal with my Audigy SoundBlaster Card. Alsa package is alsa-1.0.3-37. In Audacity I can see that it is 1/3 of what it was formerly although with Alsamixer all possible controls are set to maximum. What else can I do? There has been a thread in the Web but it didn`t turn out to meet my problem. So help is very much appreciated. Thanks Hartmut

[linux-audio-user] Icon for Soundtracker

by nigel henry

Hi folks. I've made this icon for Soundtracker using Kiconedit. I've contacted Michael Krause as to using this icon, and got the reply, "Feel free to use the icon, no problem there". Nigel. Icon attached: Soundtracker.png

[linux-audio-user] Problems with a quite complicated audio system

by Michele Spinolo

Dear guys, I am writing here because I have some problem with my setup. It is composed by: -Linux based audio workstation (Fedora Core 3 with PlanetCCRMA, RME HDSP9652) -Z-sys z-8.8a lightpipe digital detangler (http://www.z-sys.com/pp_routing.html#z8) -RME ADI-8 Pro -A modified SACD/DVD-A/DVD/CD player which is capable of outputting 6 (5.1) discrete PCM channel (for SACD a DSD->PCM conversion is performed, converting DSD to 24bit/88.2Khz PCM signal) On the workstation AlmusVCU is running, which is used as a real-time convolver. The system is connected as follows: modified SACD/DVD-A/DVD/CD player-->(3 s/pdif cables)-->Z-sys z-8.8a-->(1 ADAT cable)-->RME HDSP 2496 ADAT 1 input-->(1 ADAT cable from ADAT 1 output)-->RME ADI-8 Pro ADAT input the clock signal is generated internally by RME ADI-8 Pro (48Khz), which is connected by word clock BNC cable to RME HDSP9652, which is setted in slave mode. Z-sys z-8.8s does not have an internal clock, so this is provided through its input 1 by ADI-8 Pro ADAT output; the Z-sys unit is also setted with SRC ON, so it resample all incoming signal to 24bit/48Khz (48Khz is provided by ADI-8 Pro) on output. Now the problem is the sound is very crappy, similar to what you can hear when DAC is not synched with source signal: switching SRC to OFF on Z-sys unit provides an even more crappy sound. I tried all different clock routings I can think to, but never solved the problem: does anyone can provide some general (I know it will be hard to "get into" this setup) rules for clock signal routing in setups like mine? I also tried to play music directly in the audio workstation sending it to RME ADI-8 Pro (AlmusVCU allows this) and everything sounds fine, so I think the problem is given by Z-Sys unit. Thank you very much in advance to everyone who will reply! Michele

[linux-audio-user] Re: What parts of Linux audio simply suck ?

by Fabricio Rocha

Well... Do you guys accept the two cents from a novice user? In fact I think I am not exactly a complete novice, but I am not a developer and, although I have a lot of ideas and suggestions, I just don´t have the skill and the time for getting my hands dirty of code. This said, I would point some things I think could be better: 1) Realtime - Man, having to recompile the kernel for having realtime support is not a trivial task for the average computer user. I hope that new distros will have this module enabled by default, or at least available. 2) JACK is wonderful and I hope it keeps in evolution. I wish it can be less machine-hungry (with fewer xruns) and that the JACK transport feature support tempo changes someday soon. 3) I had a LOT of problems until I could record audio in my Audigy 2ZS card, and I think it was a problem with the Linux mixers. None of them had proper support for the EMU10K1 ALSA driver, until I could get the guts with Alsamixer. And, in fact, I still have not found a really good way for controlling sound output for all of my 5.1 speakers. I think it´s not fair to blame the Linux developers for that. But, indeed, big hardware companies, like Creative Labs, which still insist in giving only Windoze support for their products. Just look at their open-source webpage and you will know how much they collaborate with the open-source community. 4) There are already a good number of interesting music apps for GNU-Linux, like Ardour, Rosegarden and Hydrogen; but they surely have some steps to walk yet. I wish I can help their development in some way. Regards, Fabricio Rocha Brasilia, Brasil _______________________________________________________ Yahoo! Acesso Grátis - Internet rápida e grátis.

When I kill it, it starts again, for mysterious reasons, only seconds later. Sometimes, it is even owned by root, and I have to kill it as root. Even that doesnt help, it starts again and again and again. flashplayer because it lives inside a browser and should not have been allowed to occupy the soundcard. Sometimes, the only way to get sound (in proper programs, like jack), is to exit the browser. The first one is because of some crazy bug or design or whatever. The second one can probably be fixed somehow. However, it probably all goes down to the current long discussion about finding a common sound-server thing, which is definitely needed. I don't understand what happens with this crazy artsd-madness-program, and I think I'm some kind of power-user. Linux audio sucks because of this, right now, for me. esound, artsd, polyaudio, jackd; theire all the wrong solution for this problem. The correct solution is that alsa needs to be redesigned so that it can switch from direct hardware access (hw:0, 1, etc.) to dmix or jackplug and back again on the fly without the user noticing it. The second thing that needs to be done is to remove artsd from all linux audio machines around the world so that noone ever will have crazy problems with it again. At least, I wont to get rid of it on the machine I'm currently working on. Unfortunately, I'm not the administrator of it, so I can't do that. (No, I don't want any help in fixing the artsd-thing, right now I just want to hate it)

[linux-audio-user] Laptop recommendations?

by James McDermott

Any recommendations for laptops? I'm looking at Toshiba and Fujitsu-Siemens models around EUR1100. I'll mostly be doing synthesis, eg ZynAddSubFX, and programming. I'll be using the built-in soundcard, at least for now. I don't really care about battery life. The main question is: Celeron v Pentium 4 v Pentium-M? I read where Steve Harris wrote: > the Pentium M's are better for audio work (IMHO) than pentium 4's, due to better denormal handling, and can do more clock-for-clock. Is this true for Celeron-M as well (if it really exists)? Or should I definitely, definitely avoid Celeron?

[linux-audio-user] Jack capture

by james＠dis-dot-dat.net

Howdy peeps. Has anyone got jack and an sblive (value) to work for recording? I get output from the microphone (actually a guitar, but I don't think that makes much difference) through my speakers, but jack hears nothing. I have MIC set to capture in alsamixer and ac97 capture is turned up. Is there anything else I need to do? If I haven't given enough info, please just tell me. Cheers, James -- "I'd crawl over an acre of 'Visual This++' and 'Integrated Development That' to get to gcc, Emacs, and gdb. Thank you." (By Vance Petree, Virginia Power)

[linux-audio-user] debian sarge // g4 titanium powerbook // sound

by jason kahn

hi list first of all, thanks for all those who sent answers. some more questions: > you should install one a the last kernel-multimedia : apt-get install > kernel-multimedia or use synaptic to find one, Alsa will be already > configured. is there such a kernel for ppc? i wrote to the demudi list and apparently they are still working on a ppc distribution, but with no release date in sight. is there a so-called multimedia kernel for ppc available somewhere else? i now have sound working with alsa drivers. well, at least it works with pd. i still can't listen to cds. another problem is, the system sound configuration doesn't seem to get saved. that is, when i re-start i have to run mopprobe snd-powermac alsaconf then i can use the alsa mixer and pd audio runs. there seems to be no way now to control sound, aside from using the alsa mixer. where should i go from here? thanks again. best regards jason kahn
