[linux-audio-user] signal processing kits

by Fabio de Matos

Hi, I'm looking for a platform for signal processing, who can be used in command line mode ( matlab like ), but is based in low level code ( c or c++ ), and block based signal chain. I wish i could find some kind of front end to any standard plugin types. It was desirable also that the standard plugin used is able to handle data other than audio ( not so hard, i believe ), and in other domains than time ( e.g. frequency, statistical, and weirdo like domains ). Preferably it should have support for gui also, basically for plotting graphics only. thanks all, Fabio

[linux-audio-user] via82cxxx_audio

by Sakari Aaltonen

With help from a few kind people here, I got my ALSA sound working with xine. However, this was at 8 bits of color depth, and the video picture was not too good. So I tried 16 bits, which made xine fail, as it did MPlayer. But at 24 bits, MPlayer came to life and showed a picture that was (probably) as good as it gets. But... MPlayer doesn't like ALSA sound. It tries to keep video and audio in sync for 10 or 15 seconds; then it gives up and goes silent. It says my system is too slow; one of the reasons might be slow audio. So I thought I'd try the via82cxxx_audio module that is in the "official" 2.4.20 kernel. But... I can't insmod the module. It complains /lib/modules/2.4.20/kernel/drivers/sound/via82cxxx_audio.o: init_module: No such device Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters. You may find more information in syslog or the output from dmesg /lib/modules/2.4.20/kernel/drivers/sound/via82cxxx_audio.o: insmod /lib/modules/ 2.4.20/kernel/drivers/sound/via82cxxx_audio.o failed /lib/modules/2.4.20/kernel/drivers/sound/via82cxxx_audio.o: insmod via82cxxx_audio failed (No, neither syslog nor dmesf offers more information.) Am I missing a /dev? Which one? Thank you, Sakari Aaltonen

[linux-audio-user] Terratec 128i PCI and MIDI

by Steve Harris

Hi, I just bought the obove card (an ES1969 Solo-1 apparently), in order to do MIDI, but I cant seem to get anything to work. $ cat /proc/asound/Solo1/midi0 MPU-401 (UART) Output 0 Tx bytes : 1400 Input 0 Rx bytes : 0 Buffer size : 4096 Avail : 0 Overruns : 0 But I tried connecting the external midi device to ASM with kaconnect and nothing appearing in the log window and the number dont change in proc when I press keys on a keyboard. I've replaced the joystick->midi cable and I'm not sure what else to try. Help! - Steve

[linux-audio-user] quick ardour question

by Jonathan Turner

just a quick question (hopefully). In ardour I've been able to get a track to playback while recording another track, but I can't seem to play more than two tracks at a time, nor am I able to play two tracks while recording another. Is this a ALSA/soundcard limitation (I have the intel 8x0 series)? Okay, I lied, one more quick question... I've had ardour not play back samples when recording and I can't seem to put my finger one what causes it to mute the sample playback and what allows it to do duplex. Thanks all Jonathan

[linux-audio-user] OMRL - New Mailing List

by Darren Landrum

Just to let everyone know, I have created a new mailing list for the OMRL at my studioconsul.net domain. To subscribe, send a blank email to: omrl-subscribe(a)studioconsul.net To unsubscribe, send a blank message to: omrl-unsubscribe(a)studioconsul.net To send messages to the list, send messages to: omrl(a)studioconsul.net You will need to confirm your subscription or unsubscription to/from the list. I also still need to figure out how the archiving system for this list software works. This is just a quick and dirty mailing list for now, so once I get a server and the OMRL domain up and running, I will probably migrate it over there. That should not be too difficult, though. See you on the new list. :) Regards, Darren Landrum

[linux-audio-user] HDSP 9652 MIDI - A timing disaster?

by Mark Knecht

Hi, I asked about this two weeks ago but got no responses. I'm hoping this time I hear something back from other owners of the same hardware. I recently purchased an RME HDSP 9652 card. The card is working fine for audio, but the MIDI interface is a timing disaster. The interface works, but won't keep time. A 2 minute song is Rosegarden takes abut 2:45 to play every time. You can hear how the HDSP isn't delivering closely spaced MIDI events together, but is sort of smearing them out. My machine is set up using the PlanetCCRMA system. According to Synaptic my Alsa driver is from CVS:20021216. Jack is 0.44. This machine works just fine with the MidiMan 2x2 interface. No timing problems at all. Has anyone else purchased this card? Used the MIDI interface on this card? Gotten better results with this card? Can anyone suggest how I could go about fixing this myself? I'm not a programmer, so really hacking the code is doubtful, but this driver is acting like there is just a basic mistake somewhere. Possibly I could find it if I knew where to look. I hope someone will respond to this email so we can get something going to get this fixed. I really need this interface to operate soon. Thanks in advance, Mark

[linux-audio-user] m-audio radium USB midi keyboard

by Eric Dantan Rzewnicki

http://www.m-audio.com/products/m-audio/radium.php Has anyone tried using this keyboard with linux, yet? I was about to buy an Oxygen 8, because I've read about several people in the LAD, LAU, ALSA community using them with linux successfully. But, then I saw this new Radium controller. It has 61 keys to the oxygen's 25, the same 8 knobs, pitch and mod wheels, and adds 8 sliders to the oxygen's 1. Would it be too far fetched to think that this would work as easily with a linux box as the Oxygen does? I would be very happy if it would. Thanks, Eric Rz.

[linux-audio-user] swh-plugins 0.3.5 [bugfix]

by Steve Harris

The were some bugs in 0.3.4 so I'm releasing again. Sorry. * UID clash with flanger and l/c/r delay [serious] - spotted by Bob Ham, thanks * SC4 had the wrong label [mild but anoying] * autoconf script wasn't obeying CFLAGS [mild but anoying] I believe that SC4 and the lookahead limiter might be causing problems with some hosts as they have control outs. If you spot problems with these and think its the host, please contact the author. I know that ecasound and jack-rack handle it fine. - Steve
