[linux-audio-user] which alsa/oss drivers built in for 2.6.1-mm4 kernel

by Studio Zodiak

hi, I am having some problems getting alsa to play anything with maestro3 driver built in to the kernel although oss emulation seems to be working fine. Should I be leaving some of the drivers as modules? Thank you Sly Cormier ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca

[linux-audio-user] sampling at high frequencies

by Florin Andrei

Anyone here using 192kHz for sampling? I know that lower sampling frequencies (44.1, 48, 88.2, 96) are more popular, but i wonder if someone tried to use 176.4 or 192kHz with Linux audio software? If you did, what was the hardware (sound cards) and software (JACK? Ardour? etc.) that you used? Any problems? How many stereo channels were you able to use simultaneously (and what was your CPU and disk speeds)? Did you try to apply LADSPA filters on 192kHz channels? How long before the system became unresponsive and started to drop frames? -- Florin Andrei http://florin.myip.org/

[linux-audio-user] lrdf build tool changes

by Taybin Rutkin

Hi Steve, I had to apply these changes to get liblrdf to build on MacOSX. I think they should work on linux too. If they do, could you apply to the next version? Thanks, Taybin

[linux-audio-user] RME Multiface vs. M-Audio Delta 1010

Having administrated 5 delta cards (2*1010+1*66+2*44) for soon 2 years on linux/alsa at notam/oslo, whithout any trouble, I can safely reccomend delta. I also had an unpleasant experience this summer getting an rme card to work. There were lots of lots of trouble getting the driver to work somewhat properly. However, I think that was a digiface so you probably wont experience the same trouble. But, if I should choose, and had an unlimited amount of money, I would take the 1010 card. ~No doubt. --

[linux-audio-user] re: sampling at high frequencies

by BrbrOfSvl＠aol.com

->Which membrane? The basilar membrane is responsible for frequency alaysis(AFAIR), but its limited by its geometry. Doesn't it detect resonances inthe narrowing tube? Transients could be detected before the pressure wavereaches the basilar membrane, though I'm just guessing here.<- Quick review - changes in air pressure cause the eardrum to move. This causes the three little bones (hammer, anvil, stirrup) to move - these bones are responsible for a great deal of amplification of sound which is needed when you are trying to vibrate liquid from vibrating air. The last and smallest bone causes a little membrane on the outside of the inner ear to vibrate, which sets up vibrations in the fluid of the inner ear. That fluid causes the basilar membrane to vibrate (the very very short-story version of this is that the basilar membrane vibrates in different places based on the frequency). Basilar membrane vibrations, as well as the further amplification gained by active outer-hair-cell vibration causes potentials to fire in inner-haircells which form synapses with neurons which eventually send their information, cleaned up a bit, to pathways to the brain. Transients are still detected by the basilar membrane, but there are stations in the ascending pathways which deal with transient sounds differently than longer, more periodic sounds. The moral of the story is that there's still a TON of work to be done just on pitch perception - and of course even more on general auditory perception. Matt
