[linux-audio-user] Re: [Audacity-devel] Audacity supports jack in Agnula?!

by Daniel James

> Everyone needs jack, they just dont know it yet ;) Surely if Audacity is the only audio app running then it would be more efficient to access the alsa drivers directly? > If this is your feeling > then the right thing to do is to fix jack to make it less arcane. Ideas > welcome. It would be good if it could start and run as easily as other daemons - I know there are attempts being made to address this, such as jackstart. I guess it will be better when jack is fully integrated into distros, with the necessary kernel patches for capabilities etc. One of the main things that put me off using jack with audacity is that with the standalone program I didn't think I had any latency problems. I tried running jack and it told me I have xruns... Can jack verbose output be directed to a console so that you could check for xruns with ctrl-alt-f7 or whatever? I seem to remember trying this and it made the xruns worse! Cheers Daniel

[linux-audio-user] Sound on Sound, and Home Recording Magazine

by Darren Landrum

Two little things to tell everyone. First, I finally got my copy of the February issue of Sound on Sound. The Linux article is there, and I was very impressed with it. Plus, this issue has a great how-to on micing drums for studio recording. The surprise was the copy of Home Recording I picked up on a whim today, because it has an article on DIY surround sound. In the back, under the Computer Central heading, is an article called "The Other Operating System," by Thad Brown. I'll give you three guesses which one he's talking about. :-) It's a very positive article, saying that he ultimately thinks that Linux will be a serious competitor to MS and Apple for music production. The article also mentions a company called Digigram who has released drivers for their audio hardware under an Open Source license (does anybody know anything about Digigram?). He does say, though, that there seems to be no real replacement in the works for the likes of ProTools and Cubase, so I think somebody needs to point him to Ardour and Rosegarden. Just thought you all would like to know. :-) Regards, Darren Landrum

I read the article, and did "cat /proc/interrupts" and got the following: CPU0 0: 30093 XT-PIC timer 1: 356 XT-PIC keyboard 2: 0 XT-PIC cascade 8: 2 XT-PIC rtc 11: 21919 XT-PIC EMU10K1 12: 73 XT-PIC usb-ohci, usb-ohci 14: 12651 XT-PIC ide0 15: 15 XT-PIC ide1 NMI: 0 LOC: 0 ERR: 0 MIS: 0 >From what I read from the article, (and the little understanding I have about this subject) nothing seemed unusual. With the exception of the non-PCI slot IRQ's, the Sound Card appears to be before all others. The article talks about some IRQ's being shared. Would that be reflected in the output of "cat /proc/interrupts"? Before I switched my Sound Card to another slot, I thought I would disable USB in the BIOS since it's just being used for the mouse. I'm now using a ps mouse. after booting up and doing "cat /proc/interrupts" I got the following: CPU0 0: 25160 XT-PIC timer 1: 542 XT-PIC keyboard 2: 0 XT-PIC cascade 8: 2 XT-PIC rtc 11: 0 XT-PIC EMU10K1 14: 7620 XT-PIC ide0 15: 15 XT-PIC ide1 NMI: 0 LOC: 0 ERR: 0 MIS: 0 Even though there was no indication that the Interuptions (while recording) would stop, I still tried recording. I got the usual interruptions. Then I switched the sound card to the other PCI slot. There's only 2 PCI slots because the Mother Board came with onboard this and onboard that (all of which I don't use and have disabled in the BIOS). The other thing is that there's _nothing_ in the other PCI slot. But I put it in the other slot anyways. And as you can guess, I got the same results from "cat /proc/interrupts". All I can think of is that there may be a reason why my Mother Board was inexpensive. Maybe it's time to buy a new Mother Board. Can anyone think of any other solution?'

Someone on this list mentioned an article that you wrote about IRQ priority ordering and Latency using lspci. Unfortunatly, I (carelessly) did a Google search with the wrong key words. Your responce (this email) prompted me to look back at the original email. This time I used the correct keywords and it took me right to the HOWTO. It looks pretty promising. I will work with that and see if that has an effect on the situation. I wish I had done this in the first place. I wasted so much time trying to "push IRQ's around" by using the only BIOS setting available ("reserve IRQ for legacy ISA"). Partly what made this useless was that (prior to finding the HOWTO), I wasn't even sure what was a "good" IRQ or a "bad" IRQ. Besides, that was such a hap-hazard way to proceed. > 2) Some other application is stealing cycles I eliminate as much of this as possible by running ecasound without X and as root. But there could be a background process going on. I would assume (by the consistency and predictability of these "interrupts" that it's a problem with data transfer). > a) autorun trying to play CDs automatically I guess I don't understand this. If you're simply referring to the CD player being busy, I'm not running the CD Player while recording. > b) some other app started automatically Certainly possible. Thanks for taking the time to help. I will work with the HOWTO that I found and see how that works out.

[linux-audio-user] attn: cecilia users

by Austin Acton

Hi Cecilia users, I need your help. I'm making a Mandrake RPM for cecilia, and the default setting are very non-linux friendly. I don't know enough about the program or its file formats to chose good preference settings, so I was wondering what you use for the following programs in cecilia (must be GPL/BSD/MIT type license): Soundfile player (default is 'hear', don't know it) Soundfile editor (default is 'mixviews', not freely-distributable) Soundfile converter (default is 'xsox', we have that, but is there anything better?) Just wondering what you personally use for these settings. Thanks for your help, Austin -- Austin Acton Hon.B.Sc.

[linux-audio-user] While we're talking about lack of responses :-)

by Ivica Bukvic

I e-mailed the list a couple of days ago asking for some advice regarding my RTMix app ("how to make it more user-friendly"). I am still waiting for some help on this one :-D. Again, any insight is greatly appreciated! Sincerely, P.S. Web server hosting my page is still down, thanks to the "smart" university technicians... If someone desires screenshots I'd be more than willing to send them to you as an attachment (I just don't wanna do that over the mailing list because it would clutter a lot of people's inboxes).

Well, position yourself with a working ardour, and then think how much time you would spend on helping others, when all that time you could be making music :) > My annoyance is when it was asked of me to provdie more information and > I did .. no response came.. then when I tried to resolve it myself and > no further response came that's when I could only put 2 & 2 together and > see that a response I made to the string "ahem" could have been related Sometimes more information does ring a bell to someone, sometimes it doesn't. That's pretty much about it from my point of view. There are many bits in cyberspace. janne (or is there? ;) > cheers > > Allan
