[linux-audio-user] Linux audio market question

by Mark Knecht

Hi, Imagine a web site where you can pay a small monthly fee. At this site you can primarily do three things: 1) Post mp3's (et all formats) and then let people download them. You have your own 'page' (whatever that ends up meaning) to say things about the tunes, etc. 2) You get unlimited data storage for audio projects. The site would keep up to 1GB on line (i.e. - on hard drives) at all times and would store anything else on DVD+RW so that you can download it within 24 hours. Uploads and downloads could be automated so that you request it and it happens in the background. Offline storage is unlimited. If you'll bother to upload it then the site will keep it on a hard drive or DVD for you. You can control what is kept online vs. off-line at any time. 3) You can set up collaboration groups to share audio. As an Ardour user you might want to have another Ardour user do a guitar track for you. (hint hint) ;-) You'd specify what audio tracks from your archive another user can have copies of and the site would get it to them. In general the above features would come for a low monthly fee. Streaming of mp3s is unlimited until it becomes 'burdensome' at which time the system either limits access to certain tracks or charges you some more money based on a choice you make ahead of time. 'Burdensome' is probably defined by how much you're using vs. other people and how taxed the system and connectivity is. Obviously you need broadband access to make the storage part of real value. What would people pay for a service like this. How many Linux users are out there to take advantage of this? (Not that it needs to be limited to Linux...) What price makes this compelling? <$3/month? <$5? <$10? All comments appreciated. Respond to the list or to me privately. Thanks, Mark

[linux-audio-user] the Linux soundapps pages redux

by Dave Phillips

Greetings: Time is getting tighter for me these days, so I'm not always able to update the Linux soundapps sites as often as I'd like. As most of you know, I'm also not particularly pleased with the construction of the pages (plain old manually edited HTML), but I figure the present arrangement is serviceable enough to last a little while longer. Recently I've been considering how to update the sites more frequently, and I've come up with this idea: I'm wondering if it would be a good idea to assign the upkeep of certain sections of the pages to members of the community. Basically, you would ask to maintain a section, I'd say yea or nay (with about a 99.99% probability of a Yea), then whenever you wanted to update the section you'd send it to me and I'd put it on-line. It's getting to the point where I'm no longer able to decently cover every aspect of Linux audio software development by myself, and I need to find a way to more efficiently update the pages. So if you're interested in maintaining a section (or more) of the Linux soundapps pages, please write to me off-list and I'll go into more detail. Btw, you'll get credit in the section header. Does this sound at all feasible ? Best, dp

Try setting a bigger buffer... The same card, if I do not use the resampler, works fine down to buffer size of 32. I get the same error even if I try -p 2048 with the resampler. Any idea why this is so? br, Timo

[linux-audio-user] Re: the Linux soundapps pages redux

by Juhana Sadeharju

Hello. Please don't give sections to volunteers! It would make sense that members would be able to add to any pages if they wish. Adding is done quickly and easily. It is important that the new information appears on the page. And the possibility is greater if members need not have a master degree in writing. Then later, a member having extra time may re-write the pages, summarizing what was in the pages earlier. So, nobody would have to master-maintain the pages. They need not look polished all of the time. However, we could agree that some pages would be re-written by particular members --- re-writing is easier than the full maintaining.

[linux-audio-user] How to resample from 44.1 to 48 kHz?

by Timo Sivula

Hi, I have an onboard VT8235 soundcard that only supports 48 kHz sampling rate. I would like to play 44.1 kHz stufff on it and have it look like a 44.1 kHz device to jack. Is there a way to do this using .asoundrc? My .asoundrc starts like this: ------------- pcm.via82xx { type plug slave { pcm "hw:0,0" rate 48000 } } ctl.via82xx { type hw card 0 } --------------- Jack refuses to use this in 44.1 kHz. Have I misunderstood the alsa resampling? el:~$ jackstart -d alsa -d via82xx -r 44100 -n3 -p 128 back from read, ret = 1 errno == Success jackd 0.99.0 Copyright 2001-2003 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details loading driver .. apparent rate = 44100 creating alsa driver ... via82xx|via82xx|128|3|44100|0|0|nomon|swmeter|-|32bit configuring for 44100Hz, period = 128 frames, buffer = 3 periods You appear to be using the ALSA software "plug" layer, probably a result of using the "default" ALSA device. This is less efficient than it could be. Consider using a hardware device instead rather than using the plug layer. Usually the name of the hardware device that corresponds to the first soun ALSA: cannot set period size to 128 frames for capture ALSA: cannot configure capture channel cannot load driver module alsa el:~$ ------------ br, Timo

[linux-audio-user] a letter from ron parker

by R Parker

Hi Paul, Before I say anything depressing and express my frustration, please take to heart how much I appreciate what you're doing. Ardour is an incredible accomplishment and I view it as an enourmous act of generosity. I know you're trying to release 1.0 and start the GKT2.0 port at the new year. I have had enough serious problems with Ardour that I don't see how that's possible. Maybe my perspective is very narrow and I can't see beyound the issues that I run into. It's just that I keep running into problems that are intolerable to most guys like me (pro engineers). I have to share a personal frustration with you that affects my attitude for trying to help with Ardour. Because I am not a developer nobody will ever know that I have made a contribution. I feel insignificant, overlooked or unappreciated. How can I say that when everytime an issue arises you're there to help. If a developer contributes a couple bug fixes, that person recieves recognition by being listed in the developers section of the About dialog. Yet their effort seems miniscule when compared to mine. The way I read this is if you're not a developer, then in the Ardour world you're nobody. I don't know if there's any other way to interpret this. From my perspective, it seems accurate. Ultimately the result is a loss of motivation. I'm glad Doug, aka Nostar, is around these days because Ardour needs someone to discover, report and request fixes. Maybe your reaction to this letter is "go blow yourself." Given what I imagine to be your own frustrations, I sure wouldn't blame you for responding that way. There's a couple more things I want to say to express my appreciation but I have to start my day. ron __________________________________ Do you Yahoo!?

Mark: I will make a grub boot option that disables acpi and see if that helps! Thanks! Thanks all, -thewade
