[linux-audio-user] What linux-compatible card truly supports AES/EBU?

by Michal Kostrzewa

Hi List! I'm looking for a card meeting the following requirements: 0) *Linux supported* :) 1) It has AES/EBU channels (4 as minimum) 2) 192 kHz / 24-bit Single-wire and Dual-wire Modes 3) External synchronisation Master Clock or Word Clock 4) Ability to acquire data without any further on-card processing The main purpose is to connect this card to dCS converters (which have only AES/ABU) It's something like Lynx AES16 (http://www.lynxstudio.com/aes16.html) but alsa soundcard matrix shows that it's not supported... I know that HammerFall DSP MultiFace has theoretically AES/EBU but I think it's just S/PDIF - has too low signal level and doesn't work with our dCS convertes at rates >=96kHz. any help greatly appreciated :) best regards, Michal Kostrzewa

[linux-audio-user] midi troubles

by C. Villard

Thank's for all your answers ; unfortunately, I've not succeded until now ..... But I've not a lot of time left to spend now...perhaps later...so I fear that i must reconnect my atari falcon with cubase audio : great problem to print correct scores with the actuals printers, but no trouble in use !!! cordialement, PS : I think it would be great to get a cd with all stuffs nneeded, to make a linux midi station work properly ; with my poor rtc net connection, it's too diffcult

[linux-audio-user] intel8x0: clocking to 48000

by Atte André Jensen

Based on the fact that the following line is the second last displayed by dmsg, I presume my intel i810 is set to a sample rate of 48000: intel8x0: clocking to 48000 I also presume this is not optimal and should be changed to 44100, right? Where is this done? I run debian/unstable on both 2.4.23-low-latency-patched and 2.6.0/1 kernels with the latest alsa on 2.4 and the build in alsa in 2.6. Please bear with me, but I don't really know which config files to post.... Thanks in advance. -- peace, love & harmony Atte http://www.atte.dk

[linux-audio-user] RRADical WIP collection

by Frank Barknecht

Hi all, here's a work in progress collection of the state of affairs in RRADical Pd as I propose it. http://footils.org/pkg/rradical-wip-040109.tgz This includes a new and improved version of the pattern sequencer rrad.pattseq and memento and lots of more abstractions for reuseability enhancements in Pd. Impressive Screenshot of a use case is here: http://footils.org/images/rradical-wip.png Extensive documentation is missing. :( I'll regularily announce updates to my wip-collection here: http://footils.org/cms/pydiddy/wiki/RradicalPd Linux-audio-user is CC'd because maybe this is interesting to, well, Linux audio users, too, I guess. == What is RRADical Pd? == One goal of RRADicalPd? is to create a collection of patches, that make Pd easier and faster to use for people who are more comfortable with software like Reason or Reaktor. RRADical ships with patches, that solve real-world problems on a higher level of abstraction than the standard Pd objects do. All these high level abstractions (should) come with (detachable and changable) GUIs built in and use a common way of saving states. They also include a net remote control using OSC. RRAD as an acronym stands for "Reusable and Rapid Application/Audio Development" with Pd. The official home of RRADical Pd is: http://pure-data.org/community/projects/rradical/ Have fun, -- Frank Barknecht _ ______footils.org__

[linux-audio-user] 3-D Audio: To Plug-In or Not to Plug-In?

by davidrclark＠earthlink.net

On the 3-D audio (Interest in Software?) thread, I had promised to mail out something on a plug-in. It got a little too long, so rather than clog up everyone's mailbox, I went ahead and put it in: http://home.earthlink.net/~davidrclark/linux_audio_users/Plug-in.html If this isn't proper nettiquette for this user's mailing list, someone please do let me know. It would be easier just to email my ramblings. --------------------- Bottom line is: I'm not sure if it makes sense as a plug-in or not. I think I may provide the impulse response function generator and my own convolution engine, then let one of the plug-in gurus see what they can do, if they want to. If nothing happens, it'll be a command-line thingy until I get motivated to GUI it all up. No schedule, but I'd be happy to provide a crude tarball to anyone who wants to try and deal with it at any time. I PROMISE it won't be easy without some instruction. Please email me privately also so that I'm sure to see it. Thanks, Dave.

Does anyone know how to get a Midiman Quattro to work with suse 9.0? I did have outputs working at one time, but never figured out the input channels. Ther is reference to a .asound file, but not in Suse9.0 Dave

RE: [linux-audio-user] intel8x0: clocking to 48000

by Reuben Martin

Right now there is a bug in Alsa (after version 0.9.8) for intel8x0 that causes a lot of xruns (2-3 a second!) when trying to set the sample rate to 44100. I would stick to 48000 for now until that matter gets fixed. You shouldn't have any problems with that setting. -Reuben --From: Atte André Jensen-- intel8x0: clocking to 48000 I also presume this is not optimal and should be changed to 44100, right?

Re: [linux-audio-user] Audio 3-D Demo --- Any Interest in Software?

by davidrclark＠earthlink.net

Brian Redfern wrote: > Soundhack does some of this... I just took a look at the Soundhack page and the documentation for the binaural module. From the available documentation, it appears that Soundhack merely uses impulse response functions that are alreay generated, specifically that the binaural filter uses the HRTF's from Durand R. Begault. Has something changed recently? Soundhack now generates HTRF's or solutions to the wave equation? The documentation also says that you can add reverb to the results. Ugh. No, that isn't what one really wants to do for 3-D. It should all be a consistent solution to the wave equation for a particular boundary and source/sink locations, or a close approximation of it.
