[linux-audio-user] SSM 0.1.1 & noize farm

by Dave Griffiths

Hello all, I'm releasing a bit of an old version of SpiralSynth Modular, while work continues on the 0.2.0 version on sourceforge. It's got some rather nice features, and I should have released it months ago - but it had a crash bug I only found yesterday... anyway: Main app changes: Back to one window GUI with seperate movable areas Fixed Plugin window events/drawing bug Echo/Delay crash bug fix Less C code in SpiralSynthModular.C (Andy Preston) Ability to load ssm files from command line (Dan Bethell) gcc3.1 fixes + dynamic linking bugfix (Takashi Iwai) configure + make fixes (Takashi Iwai) Plugin changes: LFOPlugin (Andy Preston) MeterPlugin (Andy Preston) StereoMixerPlugin fix (Andy Preston) Scaling fix and name sorting for the LADSPAPlugin (Mike Rawes) Sequencer bugfix for dragging note events Matrix now 64X24 + tweaked GUI Matrix can be controlled by an external clock pulse Matrix copy/paste and transpose functionality (Andy Preston) JackPlugin fixed for recent versions of jack (Takashi Iwai) http://www.pawfal.org/Software/SSM/dload/SpiralSynthModular-0.1.1.tar.gz and if you want the cutting edge it's here: http://sourceforge.net/projects/spiralmodular : noize farm I'd also like to announce the noize farm, an open collection of ssm patches that are shared in the spirit of the GPL: http://groups.yahoo.com/group/noize_farm/ Feel free to download, hack, modify, upload and generally have fun with anything you find there. It's currently hosted at yahoo, which means you have to sign up with them to get access to the files - but we think it's worth the hassle for now. I don't see it as being restricted to just ssm patches either, if you like the idea then you can share anything (linux) audio related - as long as the files are small, and open for all to play with. All the best, Dave : www.pawfal.org :

[linux-audio-user] usb midi question...

by m

hi all, got a quick q about usb midi in alsa... i've already built my alsa-driver (0.9.rc3) for snd-usb-audio, to run my quattro.... but i've just been given an Evolution UC-16 on trial, which is usb midi. so normally, i'd rebuild my alsa-driver ./configure --with-cards=usb-audio --with-cards=usb-midi but it will only ever build just one of the drivers if i do that (usually the last one in the list)... is there a way i can build usb-midi *and* usb-audio? i'll probably be doing quite a bit of testing with usb-midi, but will mostly be running usb-audio for my own use. or is it possible to build the alsa-driver for usb-midi and manually copy it into place? thanx in advance m~ -- iriXx www.iriXx.org copyleft: creativity, technology and freedom? info(a)copyleftmedia.org.uk www.copyleftmedia.org.uk _ ( ) ascii ribbon against html email X / \ cat /dev/sda1 > /dev/dsp *** stopping make sense ***

[linux-audio-user] Speaker Jack

by linuxmedia4＠netscape.net

Greetings, I just bought a new system. It has integrated sound on the Mother Board. There is a jack marked "spk" (obviously the speaker jack). But the manual refers to that jack as "line-out" I was always under the impression (just an assumption) that "line-out" and the speaker jack put out completly different voltage levels (and we know how dangerous it could be to plug things into the wrong voltage levels). Are the standard speaker jacks indeed "line level"? There's several possiblities that I can think of: 1. The standard "speaker out" jack complies to the "line level" standard 2. Since it's a costom made computer, the jack is incorrectly marked and its actually a line out jack. (after all, the VGA port is marked as "COM2") 3. Since the manual covers several versions of their Mother board, it's actually a different interface that it's referring to (I've run into this with the manual before). I'm actually hoping to find out that the speaker out jack complies to the line level standard. This way I can use the speaker out for line level devices. Let me know what you know, Thanks, Rocco __________________________________________________________________ The NEW Netscape 7.0 browser is now available.

[linux-audio-user] m-audio quattro and alsa mixer

by m

hi, i've just got a m-audio quattro (very nice :) and have alsa running happily... but i'm having trouble starting the alsamixer. i've copied in Patrick Shirkey's scripts for .asoundrc and qinit, but when i run qinit it segfaults :(... alsamixer says 'no mixer elems found' and when i run gnome-alsamixer i just get a blank screen with 'USB Audio Quattro' at the top. i'm getting sound fine out of applications such as xmms though... although SpiralLoops crashes and/or produces digital glitch noise when i import a sound.... any ideas? thanks in advance m -- iriXx www.iriXx.org copyleft: creativity, technology and freedom? info(a)copyleftmedia.org.uk www.copyleftmedia.org.uk _ ( ) ascii ribbon against html email X / \ cat /dev/sda1 > /dev/dsp *** stopping make sense ***

[linux-audio-user] SACD backup?

by Alexy Khrabrov

Greetings -- I've got two toys recently, an HP200e DVD+RW and a Sony NCD650 5 DVD/SACD/CD/VCD player. HP backs up a DVD in 5 minutes, 24 minutes reburn. Sony plays the transcoded VCDs, which are inferior and I just did it to see that fact. But with the SACD, I can't find any info on ripping it. Can I use my DVD+RW HP to read it in? And why isn't there toslink output on the Sonly for SACD -- it says it's for DVD only, and indeed nothing comes out when I use the optical, I have to connect 6 cables and switch the receiver into DVD 5.1 ch mode to hear the SACD, and then the subwoofer is surprisingly soft (even with the +10dB max increase on the Sony). Mind you, my sub is a 3 ft tall Yamaha w/Helmholtz folded tube inside, it rocks the house with DVDs... Any hints on SACD backup would be appreciated! Cheers, Alexy

[linux-audio-user] freqtweak trick of the day

by Jesse Chappell

Here is neat hack with the pitch scaling capability of freqtweak: Pseudo Formant Corrected Pitch Scaling To avoid the chipmunk effect when pitch scaling voices, try this in freqtweak: Hold down Control and drag from about 1 or 2kHz off the left edge at the desired pitch adjust. This effectively shifts the fundamental of the voice but leaves the higher frequency formant information alone. It definitely has artifacts, but really isn't too bad on female voices. Play with the cutoff point (reset the filter with Ctrl-Alt-Right click and try again). Using a log freq scale (middle-click) might help find the best cutoff. For some general info on vocal formants see these pages: http://dspdimension.com/html/timepitch.html http://dspdimension.com/html/formantcorrection.html jlc

[linux-audio-user] latency questions

by G. M. Bodnar

I was running through the low-latency howto and I ran into a couple things that seem to be hindering process. First off, I'll mention that I'm using a Dell Inspiron 2650 laptop. I'm running debian unstable with 2.4.19. 1) DMA transer won't enable. I've enabled DMA transfers in the kernel as suggested by the howto. However, I'm unable to turn on dma access with hdparm. I'm told the operation is not permitted. 2) IRQ mess. dmesg lists that almost every device that is detected is on irq 10, including the onboard sound (i8x0) and video card (nVidia). As a result, in X, I get static and pops as the audio is delayed. Searching further, I noticed a message saying the APIC wasn't being used due to a buggy bios provided by Dell. This could explain why everything is pushed to IRQ 10. Has anyone had these problems, and more importantly, gotten around them? I'm not sure if the bios problem mentioned is accurate for the 2650. Looking through the kernel source, it clumps a bunch of models together. I'm tempted to hack through that and see if it does crash... Thanks Greg --- -
