[linux-audio-user] Sounds Expo in the UK

by Daniel James

Hello all (especially UK and Europe based list members), There is a trade show called Sounds Expo 2004 taking place at Wembley, near London, on the 10th - 12th February next year. The exhibitors include most of the major studio technology companies, and the media sponsor is Sound on Sound. Would members of this list be interested in doing a Linux Expo/LinuxTag sort of stand at this event, showing off JACK, Rosegarden, Ardour, JAMin, Audacity etc etc? In some ways it makes sense to target musicians, engineers and producers rather than just general Linux users. I think it could also be useful in raising awareness among the hardware companies that will be there. There is no community area at this event that I can see, but there are some free seminars being hosted by SoS, a Steinberg/Native Instruments theatre and 5.1 workshops. It's just possible that the organisers may allow a free stand on the basis that it's a not for profit (dis)organisation offering free advice to event visitors. What do you lot reckon? If there are enough people who would be willing to be on a stand to cover the three days, then I will approach the event organisers. Daniel

[linux-audio-user] Sampling rate problems on a VXPocket v2

by Geoffrey Martin

Hi, I'm using the following: IBM T40 laptop Digigram VXPocket v2 RedHat 9 Kernel 2.4.22-ac4 ALSA drivers 0.9.8 vxloader 0.9.7-i686 Measurement gear Audio Precision System Two Cascade PrismSound DSA-1 Some of my other gear is having difficulties locking to the S/PDIF output of the card at 44.1 kHz and I have a suspicion as to why this is happening... I have control over the sampling rate of the S/PDIF output of the card as I would expect, however... In the S/PDIF Channel Status Block information there is a portion of Byte 3 that is used to send the intended sampling rate (selectable between three values, 32 kHz, 44.1 kHz and 48 kHz, depending on the arrangement of bits 0-3 in Byte 3. For specific information on this, please see Application Note AN22REV2 from www.crystal.com). It is also possible, using bit 0 of Byte 0, to indicate whether the signal is Professional or Consumer format. Using my present configuration, I do not appear to have control over either of these two variables. For example, even when I am sending a 44.1 kHz signal at a rate of 44.1 kHz (or close enough... it's actually 44.0993, -17 ppm) Byte 3 of the Channel Status Block is saying that the signal is a 48 kHz transmission. Are the VXPocket drivers in ALSA capable of changing these values in the card? The official drivers for Mac OSX allow me to change the Pro/Consumer flag using an application, and the sampling rate indicator changes automatically with the actual sampling rate of the card's output.

[linux-audio-user] stretching sound

by Julien Claassen

Hi all! I've been trying to stretch a soundfile. It is a piano track with mostly two voices only. I did it with an fft plain phase vocoder. Now there are a lot of parameters and I got some undesireable delay. In general the stretched sound was good, but the delay is disturbing. So here's the question, how should I set the following parameters to get the best result? fft-length (as high as possible?), windows per second, window length, windowtype (hamming, triangular, kasier with several coeffecients). Any ideas or practical experience with that? - I'm NOT doing it in realtime, so CPU-time is no problem. I've got time! :-) Thanbks for any help or good ideas!

[ someone ] >As someone who runs a business, why would I want to pay someone $600 to >fix 10 documents when I can buy Microsoft's tools for $300 and have >guaranteed compatibility? That's a tough sell... Hello. We should have a law which says the file formats should be open formats. People who write and make documents should have a vendor independent access to the documents. At meanwhile, why one should be able to read Word and Excel documents in Linux? One can always ask clients to print to the good old paper or to an image file. Regards, Juhana

Which is usually very minimal for such a large list. In my opinion a separate OT is pretty useless, from the standpoint that the people who normally ignore list rules and post random crap, are not going to join the OT list. m.

RE: [linux-audio-user] trying to midiconfig still

by Matthew Allen

The boot option is 'knoppix alsa'. However like I mentioned before Alsa is killed on the hard drive install. If you have done a HDD install could try the alsa-autoconfig script in /etc/init.d ut your best be is to wade through an Alsa keyword search on the knoppix.net forums. > -----Original Message----- > From: Joern Nettingsmeier [mailto:nettings@folkwang-hochschule.de] > Sent: Wednesday, December 10, 2003 1:23 AM > To: A list for linux audio users > Subject: Re: [linux-audio-user] trying to midiconfig still > > Kevin Ryan wrote: > > Ok, I'm still trying to find out how to configure the > > midiports of my Knoppix 3.3 system (how to find out > > what the input/output device is in /dev) > > > > And trying to see if my driver is Alsa or OSS. > > > > There is no aconnect or kaconnect command. > > No /dev/snd or /dev/sndstat or /proc/asound. > > > > relevant entries from lsmod command are: > > sb 7796 > > sb_lib 33550 [sb] > > uart401 6052 [sb_lib] > > sound 55276 [sb_lib uart401] > > soundcore 3428 [sb_lib sound] > > you are using oss. > > iirc there's a boot option in recent knoppixen to use alsa instead. > > > I didn't see anything relevant out of the long > > /etc/modules.conf (if I need to post something > > specific there, let me know...) > > > > Help anyone? thanks... > > > > > > > > __________________________________ > > Do you Yahoo!? > > New Yahoo!

[linux-audio-user] [admin] topic?

by Joern Nettingsmeier

hi everyone! this list has been very busy lately with off-topic exchanges on linux (and windows!) applications and their respective advocacy in general. the off-topic traffic seems to be drowning the audio-related discussions. i don't really mind and it's not up to me do decide, but i'd like to ask you to consider all the folks out there with crammed inboxes who thought they were subscribing to an audio list ;) in any case, the discussions (whether on-topic or not) show what a nice place lau has become, and how much people like to hang out and just chat about anything. ;) take my comment as a suggestion only, if you feel you need to reply, consider to do it in private mail, and for a quick chat about not-so-on-topic things with your linux audio pals, try #lad at freenode.org. (and come to karlsruhe and to linuxconf.au and to linuxtag next year, of course!) all the best, jörn -- Happy Birthday, Professor !

[linux-audio-user] trying to midiconfig still

by Kevin Ryan

Ok, I'm still trying to find out how to configure the midiports of my Knoppix 3.3 system (how to find out what the input/output device is in /dev) And trying to see if my driver is Alsa or OSS. There is no aconnect or kaconnect command. No /dev/snd or /dev/sndstat or /proc/asound. relevant entries from lsmod command are: sb 7796 sb_lib 33550 [sb] uart401 6052 [sb_lib] sound 55276 [sb_lib uart401] soundcore 3428 [sb_lib sound] I didn't see anything relevant out of the long /etc/modules.conf (if I need to post something specific there, let me know...) Help anyone? thanks... __________________________________ Do you Yahoo!? New Yahoo! Photos - easier uploading and sharing. http://photos.yahoo.com/

[linux-audio-user] Recording from SPDIF with SB live

by lau＠hippie-online.de

Hi linux-audio-users, I am a newbie in this list - so first of all hello to everybody! :-) Can anybody give me some hints about my following problem? I would like to record directly from my DAT recorder (48 kHz) via SPDIF. As a greenhorn in harddisk recording I expect that there should be a way to get an exact copy of the data on the tape with no input level / mixer and no DA-AD conversion in between?! Unfortunately so far I did not succeed in recording from the SPDIF-input at all. I am just able to route the DAT signal to the analog line out by setting its volume using alsamixer. But the SPDIF-in does not appear in other mixers like kmix and the signal is not available in recording programs like audacity or krecord. :-( I am using: - SuSE 8.2 / kernel 2.4.20 / i86 - alsa 0.9.0 - emu10k1 - Soundblaster live! rev. 4 Ciao, HippiE
