Hej to all, I used to work with the really nice loopbased timestretching music application ACID on windows. Is there any equivalent on linux ? Thanks a lot -- A l e x

[linux-audio-user] RE: [linux-audio-dev] RME Hammerfall DSP Cardbus+Multiface

by Mark Knecht

Paul, Great info. I didn't know about modinfo. Is there a way to query what the current setting of these parameters are? It seems that I'm told I have a range to work in, like 1-8, but no indication of how they are currently set or what they do. (Maybe only read the code?) I'm sure that many are just on/off sorts of things, but some clearly are not.

[linux-audio-user] RME Hammerfall DSP Cardbus+Multiface

by D. Sen

Hi, I have just bought myself the Cardbus+Multiface RME system. I think I have finally gotten the alsa modules (snd-hammerfall-mem and snd-hdsp) to load correctly along with the OSS emulation modules. BUT I cant seem to play anything out of the Lineout/Headphone output. I have tried various 'amixer cset' commands but all I get is silence (trying to play a simple wav file using aplay). Any suggetsions? -- --------------------------------------- D.

Well done, guys! Im really impressed, being able now to play and record from/to several MIDI sources, and work with a long session without a single crash. Thank you very much!

[linux-audio-user] AD/DA

by linuxrob＠dod.net

Thanks for the info but I still have a few questions. Does the AI3 support 96 KHz like the ADI-8 DS does? I know it supports 24 bit, which is useful. Does the ADI-8 DS do anything the AI3 can't? the price difference is huge, and I don't really see all that much of a difference. Thanks! Robert Cohen Also, where can I find a copy of the HDSP 9652 drivers?

[linux-audio-user] at my wits end

by iriXx

i dont quite know how to do this any more.. getting to wits end still going with usb audio stuff have tried with and without the devfs stuff in modules.conf have tried with alsa tarballs and without them have tried instructions as per kevin's site nothing seems to be working: xmms says this: [root@hamish miriam]# ** WARNING **: oss_open(): Failed to open audio device (/dev/dsp): No such device similiar results for alsaplayer please help! i'm at my wits end! ;-) cant explain why it would work 2 days ago and wont work now i've tried repeating everything i did then (which was just to make sure mandrake libalsa2-devel and libalsa-data rpms were installed and then clean out modules and install again from tarballs. it worked, i dont know how it worked but it did). the only thing i can think of is those weird warning messages i got when building alsa-driver, it was something about the records in /lib/modules/2.4.19-16mdk/kernel/sound/ saying that this was the same location i have used before does anyone know what this means? or how i should proceed? thanks 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] mpg123-streams and ecasound/lame-padding

by Christoph Rupp

Hi, i convert a live-stream with ecasound to MP3s; but mpg123 has a lot of problems with the stream. i have discovered that here and then there's an mp3 frame with Padding set to 1 and as soon as the first padding-frame appears mpg123 starts to get a hickup. The only lame-option i use is the following: ext-mp3-output-cmd = lame -b 64 -a -m m -x -S - %f (i need a mono-64kbit-stream) I have searched the lame man-page but haven't found any switch to disable the padding. any idea what i could do?

[linux-audio-user] ANNOUNCE: Rosegarden-4 0.8.5 released

by Chris Cannam

The Rosegarden team have the pleasure of announcing the latest release of their MIDI and audio sequencer and score editor for Linux. The source code is available now from the project homepage: http://www.all-day-breakfast.com/rosegarden The availability of binary packages depends on their various maintainers; please check the project homepage for more information. New features since the 0.8 release include: o Improved MIDI file I/O: better support for banks and merging in import, better support for delay, transpose etc in export o MIDI device Bank and Program editor, including import and export of Studio data o MIDI Panic Button for clearing down stuck notes o Added some keyboard controls to matrix o Added real-time segment delays o Progress display completely overhauled o ALSA clients can be added dynamically (you can change your soft synth configuration while Rosegarden is running) o MIDI events filter dialog for MIDI THRU and MIDI record o MIDI/ALSA recording bug fixed (stopping after so many recorded events) o Many bug fixes, tweaks and performance improvements Unfortunately we've had to drop KDE2 support from this release onwards as it was getting too difficult to maintain both KDE2 and KDE3 in the same development tree. We're hoping this won't affect too many users in the long term. Finally, we would like to thank the cachegrind/kcachegrind team for a truly useful development tool. Chris

[linux-audio-user] Ecamegapedal - please help!

by felipe

Hi everybody I play guitar and needed a good non-commercial FX processor to turn my PC into a little guitar studio to improve my knowledge of guitar FX and such. I "apt-got" ecamegapedal and ecasound (debian woody here), I then deinstalled them and downloaded and installed the latest source releases (ecamegapedal-0.3dev1 and ecasound-2.2.0-rc1)... but still I have a problem: Everything works fine except I can't use ecamegapedal as a realtime effects processor! It works totally amazing when I set <Input> to a wav file, but when I choose "arts" as input AND output it does just nothing. My guitar keeps producing the same clean sound no matter which effect I choose. My soundcard is an OPL3SA2 and it should be full-duplex, as I can hear using software like GNUITAR, ExEf, Stompbox2 ecc ecc. I just wanted to use the superior capabilities of ecasound. Oh and I also tried to test ecasound from the command line with something like: $: ecasound -i:arts -o:arts -a:felipe -c That works, although the signal I get is a bit delayed, maybe there's some argument I could pass to have it adjust the output... BTW the real important thing to me was to have a good and intuitive guitar-FX-oriented interface to ecasound, and I think ecamegapedal is the way to go. Please could you help me? I'm attaching some output I get when I start ecamegapedal or ecasound. Best Regards and Keep Up This Good Work! -felipe- PS: I also tried other ecasound related software, like tapiir and tkeca... but they look more like mixers and I just want a realtime effects processor ;-) -- Prendi GRATIS l'email universale che... risparmia: http://www.email.it/f Sponsor: A Natale regalati un computer e risparmia: 120 euro di sconto su DELL Dimension e Inspiron!
