[linux-audio-user] searching a audio-server application

by René Oelke

hi folx, i am new at this list. so this ist my premier question. :) is there an application, that can solve the following problem: 1. run as a server-process 2. load some midi-data in it and create a virtual midi-track with this data 3. put an instrument on this track with a defined preset 4. render the whole track into an audio-format (i.e. wav, aif) 5. compress this in ogg/mp3 6. save and close the song the same should be possible with an audio-track instead of an midi-track. but here i don't want to put an instrument but an plug on it. just imagin that you have a virtual, full-remote- automatable cubase-server. :) this solution could be useful for an internet-remote-audio-creation application. thx for response, rené ------------------------------------------------------------------ | ____proAudioSys - professionelle Audio-Systeme______ (~) /___www.proaudiosys.de_____________________________ # / __X____ #/___René Oelke__Neue Bahnhofstr. 26__10245 Berlin__ | | | | /___030 / 29003200__0179 / 4594543_________________ | | | |/___r.oelke(a)proaudiosys.de_________________________

[linux-audio-user] permissions of /proc/asound/card1/pcm0p/oss

by Atte André Jensen

I cannot figure out how to automatically set permissions of /proc/asound/card1/pcm0p/oss. I tried Having the line options snd major=116 cards_limit=4 device_mode=0660 in /etc/modutils/alsa, but alsa won't come up, saying: "Unknown symbol device_mode". Google tell's me that is a common problem. Is there a new way of setting the permissions of /proc/asound/card1/pcm0p/oss or /proc in general??? This is on kernel 2.6.4... -- peace, love & harmony Atte http://www.atte.dk

Re: [linux-audio-user] Quattro USB (EMI 6|2m)

by Jorma R

Hi, I have the EMI 6|2m. The card works ok with Jackd - at 16-bit and with a large period size. The card records cleanly at 24-bit too but gives strange noise when connecting Jack ports. So it works but not perfectly. If any suggestions on how to ipmrove the performance with jackd would be more than welcome. -Jorma > Thanks again everyone. > I have decided to get a EMI 6|2 and plug it in to see if it will work. > If it does not, I plan on shelling out the cash for the VXpocket 440 PCMCIA > card. > Thanks again for all of the input.

RE: [linux-audio-user] Quattro USB

by Reuben Martin

> Thanks for the reply, > As I am only in the posession of a laptop, PCI is not an option. > Are there any PCMCIA otions out there, or should I wait until > Firewire/USB 2.0 > becomes more available? I don't think the audio spec changes with USB 2.0. That would make backwards compatability a little tough, but I may be wrong. I'm not familiar enough with firewire and PCMCIA audio devices to provide useful advice on their pros and cons. Using a laptop, you may not have much of a choice but to use a USB device. In that case maybe some people on this list could provide you with some advice on success (or lack thereof) when using USB devices with Jack. There's lots of reference to troubles with the Quattro on the Jack Dev list, so try looking around and see if there's anything that works better before settling on what you want to buy. -Reuben

[linux-audio-user] [ANN] realtime-lsm-0.1.0 available via SourceForge

by Jack O'Quin

The first SourceForge release of realtime-lsm (0.1.0) now available. http://prdownloads.sourceforge.net/realtime-lsm/realtime-lsm-0.1.0.tar.gz?d… The Realtime Linux Security Module (LSM) is a loadable extension for Linux 2.6 kernels. It selectively grants realtime permissions to specific user groups or applications. There are only a few small differences between this release and the realtime-0.0.4 version released back in March. If that was working satisfactorily, there is no need to upgrade. The main purpose of this release is to take advantage of the services provided by SourceForge. (*) The module now declares the appropriate kernel vermagic string, thanks to a patch provided by Guenter Geiger. (*) Although the SourceForge project name is `realtime-lsm', the module it builds and installs is still called `realtime' and supports the same user interface. This LSM was written by Torben Hohn and Jack O'Quin, who make no warranty concerning the safety, security or even stability of your system when using it. But, if you do have problems, we would like to know about them via the SourceForge bug tracking system. -- joq

[linux-audio-user] pd vs. supercollider

by Tim Blechmann

hi all, since i'm about to rewrite my (pd) performace patch, i'm curious if i should switch to supercollider ... i heard that (on macs) supercollider computes much more efficient than max/msp ... is that somehow compareable to linux / i686 / pd? has anyone tried to run benchmarks with similar patches on both programs to compare the cpu usage? cheers...

[linux-audio-user] anti-compressing?

by Andrew Gaydenko

Hi all, Few days ago there was discussion in the list about mastering-CD/compressing/ limiting/gain-upping and so on. I have strange feeling from the discussion. Does it mean, that, indead, we (all CD-listeners) listen DAMAGED with such compressing music? I don't mean any music/sound engineering work! I'm saying about market demands (compressed music is more sutable for cheap audio quipment, isn't it? And compressed sound seems to be better at low volume level, don't it?). If it is true (i.e., a market demands to damage music) - are there any (software) tools to anti-compress a dynamic range? And - is it worth even to try to expand dynamic range? P.S. I'd like to repeat, I don't say about engineers work - they try to do their work as good as possible, I think. I'm saying about a market influence to music quality. Andrew

[linux-audio-user] Workstation - Collaboration

by aacton＠yorku.ca

Hey, My crappy, year-old "Mandrake Audio Workstation HowTo" is horribly out of date, and is still receiving many many hits per day. Since I don't have time to rewrite it, I've made it community-accessible on my new site. If anyone wants to help edit/update/add content, they can via the web at http://groundstate.ca . Todo: - update to Mandrake 10 - revise for 2.6 kernel - add MIDI information - tidy up the hellish HTML Also, if anyone wants to start another community-edited linux audio book, let me know. Austin

[linux-audio-user] Newbie questions for live gigging

by Richard K. Ingalls

I've been lurking on this list for a few months... I haven't even created a Linux Digital Audio Workstation yet, but I'd like to. I'm becoming more and more a believer in Open Source Software not only on the server but also on the desktop... (I digress, sorry). I'm looking at the latest MIDI sound modules and thinking can't I achieve many of these things using Linux and my PC? 1) I want to have many sounds available for live playing (via MIDI) on my keyboard. That's the top priority. Lots of sounds. Good quality sounds. I'm thinking a sample playback machine or sound fonts (right?). Can't I even achieve BETTER sounds with my PC than with a very expensive new sound module? 2) I'd like to be able to sequence those great sounds. It would be even better if I could use the sequencer WHILE playing live sounds through this machine. 3) It would be very cool to be able to edit those sounds and tweak them. Doesn't have to be "live" though. MY QUESTIONS: Can I achieve these goals without too much fuss (remember I'm a newbie)? Which "distro" (CCRMA or other?) would be best/easiest? Do I want to go with sound fonts? What sound card should I go with (not too expensive, ok?)?

[linux-audio-user] regarding SCons

by Dave Phillips

Greetings: I'm happy to see and hear another release of CheeseTracker, but I have a couple questions regarding SCons. I'm not opposed to its use, it appears to resolve many issues for cross-platform builders, but since it is relatively new (and I'm relatively old) I'm a little confused by it. The SCons FAQ is pretty much just useless history and doesn't answer the following questions: 1. Apparently SCons does without the need for anything like 'make depend' or 'make clean'. If that's true, does it mean that SCons builds fresh every time, i.e., that it autoerases the compiled objects ? 2. If something like 'make clean' is supported, how do I invoke it ? What can I do if I don't want automatic erasure of the object files ? 3. No man pages, that sucks on a UNIX/Linux platform. The GNU autotools have them, SCons should have them too. 4. No 'scons uninstall' ?? Again, if I'm missing it, please inform me how it's invoked. CT and Csound are now the only two apps on my system that use SCons. The maintainers of Csound couldn't make the autotools work for themselves, so now you must add downloading and installing SCons (and an up-to-date Python) to the process of building Csound. Happily, that isn't especially difficult, but it does add another layer of complexity to the process. More to the point, why don't the mainstrean Linux distros include SCons as a matter of course ? Best, dp
