Greetings, I was curious what compiler versions people have had the best luck with. I am currently using: gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-113) I am considering upgrading via RPM to what appears to be 3.2 (gcc-3.2-7.i386.rpm). Good idea? Bad Idea? Thanks! Levi

[linux-audio-user] The Open Music Resource Library - Licensing

by Darren Landrum

Hello, all! I hope everyone had a good holiday season. As for me, I was busy moving into a new house (I'm a first-time homeowner, which is scary), so I've not had a chance to do any more work on the library. That will change now, however, as I now have my cable modem back, and a new broadband router to boot. :) I can now set up my older AMD 750 as a development server... Eventually. So now, it's down to brass tacks. I figured before I start to work in earnest on the technical aspects of the OMRL, that a good subject to tackle would be the required licensing of the content uploaded to the site. In reviewing this subject over previous emails, here are the conclusions I came to: 1) Users should be free to download, use, and redistribute for no cost any and all loops, samples/sample sets, and patches. 2) Users should be free to use any loops, samples, and patches in their final musical works, regardless of whether that final work is free or for-profit. 3) Users will *not* be free to download any loops, samples, and patches (raw materials) to package up and sell on a for-profit basis. Basically, you can use anything from the OMRL in your final product and sell it (or give it away), but you cannot sell any of the content of the OMRL itself, for example, selling a loop library CD containing loops from the library. Does this make sense to everyone? Would this be an acceptable solution to the problem? Thank you for all of your help and support. Regards, Darren Landrum

[linux-audio-user] HDSP 9652 MIDI Timing

by Mark Knecht

Paul, I've done a bunch of work over the last few days with a problem I was experiencing using Rosegarden to play MIDI and then receive and record the audio from external sound sources in Ardour. First, yes, it really works, and actually works pretty nicely. Jack, Ardour and Rosegarden are all playing nicely together. However, I have found that: 1) There is a severe timing problem when using the HDSP MIDI interface under Linux. Over time the HDSP 9652 just gets further and further behind. 2) There is no problem with the HDSP MIDI interface under Windows. 3) Thee is no problem with the MidiMan 2x2 interface under Linux. The problem seems to be pretty clearly the way the Linux stack is using the HDSP 9652 MIDI interface. I'm guessing it's a driver problem, but I don't want to color the perception. I know it's a newer driver. How can we go about debugging this and getting it fixed? I can post mp3's of all these cases for people to hear if it is desirable. I have lots more technical data to relate once we decide how to go about solving the problem. Thanks in advance! The fact that I have all this software working as well as it is is a great accomplishment for me, and due to a lot of great programmers out there like you guys! Cheers, Mark

[linux-audio-user] 24bit 96khz cards that work well

by Brian Redfern

Well, I figured out that the culprit to my xrun problem wasn't my 533mghz processor, its my envy24 chipset based card, from the alsa wiki: "Many but not all users complain about sound glitches. This may be due to the cards being IRQ hungry. (VU meter interface?) -- Tobiah" Given that the evil envy24 chip is in a lot of cards out there, I'm wondering what cards people have had better results with? http://www.brianredfern.org

[linux-audio-user] What wave-editor to use for voice removal?

by Remco Poelstra

Hi, For a musical I've to remove the background choirs from a karaoke cd. The CD sounds like it's MIDI, and it's some simple music. I hope I can remove the choirs by overwriting them with other parts of the song that have the same instrumental parts. The problem is that I can't find a good editor to do so. I need some multitrack capabilty, to lay all the different parts on different tracks for easy editing. I need some form of volume-envelope/automation for smooth fading of the tracks (fade in/out plugins are not an option because I need to tweak it and that's difficult with plugins that work on selections). The obvious candidates like audacity and ardour don't work, because audacity has no markers, so I can't find back the positions from where I cut and ardour is too buggy to use. I've looked at linuxsound.at for editors, but most are still too much under development. I hope someone here can give me a good hint on what editor can be used. Perhaps I missed a feature in one editor that can help me? What editor would you choose? Thanks in advance, Remco Poelstra

[linux-audio-user] new computer woes

by Anthony

Thought I'd post to see if anyone has any advice. I've just built a new SMP machine: Asus A7M266-D, 1.0 Ghz Athlons * 2. I got some nice fans from endpcnoise.com (Molex) that are virtually silent and a Power Supply which is louder than what I'd hope but very reasonable for 400W's I suppose (dunno). I installed gentoo, latest alsa, etc... Unfortunately playback is distorted during video load. It is *not* a CPU load issue - I can playback just fine while compiling the kernel with make -j3. If I scroll pages up and down in galeon the sounds slows down :o. Jack doesn't report Xruns but sometimes delays when I do this. This occurs both with the onboard C-media chip and my Delta 44. I struggled for a long time to get the IRQ's not to share. I tried all the suggestions in the Audio Quality HOWTO. The video card is a PCI GForce 2. It was in my old machine and didn't cause any problems (while my old onboard AGP did create some noise). The only thing I can find is the PCI Latency settings are all set to 32. This seems odd I suppose, so I tried higher settings for the video to give it more bandwith and other variations with no success. I might go out and buy an inexpensive AGP card tomorrow, but I'd hate to find out the problem is deeper than that. Kernel is 2.4.20 vanilla tried with and without lowlat. Maybe I should back down to 2.4.19? Any suggestions? TIA --ant
