Hi all, the following announcement gets sent to all of linux-audio-dev, linux-audio-user and linux-audio-announce mailing lists in order to reach as many possible interested parties as possible; I'm sorry if you receive this twice or even more often. I would be glad if we get a lot of participation from your side! Frank ----------------------------------------------------------------------- >From April 29th to May 2nd, 2004, the Institute for Music and Acoustics of ZKM Karlsruhe, Germany, will host the 2nd conference of the Linux Audio Developers (LAD). As a new feature there will be presentations of music in addition to technical talks. For this, we are looking for music that has been produced completely or mostly under Linux. We are looking for: * Interesting demos of sound synthesis, sound processing, etc. * "Classical" computer music compositions, to be played in a concert setting * Pieces from areas such as Electronica, Chill-Out, Ambient etc. If you would like to participate, please send your composition(s) to this address: Linux Sound Night ZKM, Institut fuer Musik und Akustik Lorenzstr. 19 D-76135 Karlsruhe Germany Please make use of one of the following media formats: - Audio-CD, DVD or CD-ROM Possible audio file formats: aiff or wav; mono, stereo or multi-channel; 44.1 or 48 kHz; 16 or 24 bit resolution. Please include the following items with your submission (in English): * A short commentary on the compositions * A short Curriculum Vitae * A completed and signed printout of the form available here: http://www.zkm.de/lad Deadline for submissions is February 29th, 2004. A jury will select the compositions that will be performed/played. The jury will award 3 grants to participants to contribute to their travel expenses. Terms and conditions for participation can be found in the form above. Up-to-date information about the conference is available here: http://www.zkm.de/lad

Yes, you are right, this works (and is not possible using alsamixergui) - thank you! *But* it definitely results in a DA-AD conversion because - I can record in arbitrary sampling rates without problems - When I stop the tape the input level remains about -70 dB Is this a particular weakness of the SB live? What card supports exact recording from SPDIF-in? Ciao, HippiE

[linux-audio-user] Core-Sound PDAudio-CF [for laptop?]

by derek holzer

Hi everyone, Curious about the use of this PDAudio-CF card under laptops. Dave Phillips is the website's "poster boy" for this, and I thought maybe he or somebody else that has checked it out could post an evaluation for it here. I am considering it as the Hi-res soundcard for a Pismo Powerbook running Gentoo, primarily because it seems cheaper than getting another cardbus HDSP... Thanks, D. -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 57: "Do the words need changing?"

[linux-audio-user] Festival help needed

by Julien Claassen

Hi all! I'm still trying to install a good working festival system. But still I'm not sure about the components needed and in which order to install the items. Can anyone help me with a bit of practical advise? Like: which tts-app to choose, which languages are good (english and/or german)... Does anyone know, if mbrola voices work together with festival? I read something about it, but again I'm not sure. Thanks for any help and advise!

[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!

[linux-audio-user] Re: Is the Linux desktop really here?

by Juhana Sadeharju

[ 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
