[linux-audio-user] [ANN] LinuxSampler 0.3.1

by Christian Schoenebeck

LinuxSampler [1] is a modular, streaming capable sampler. It was designed decoupled from any user interface, that is as sampler backend which can be controlled via network connection from an arbitrary place, using a custom, ASCII based protocol called LSCP [2]. [1] http://www.linuxsampler.org [2] http://www.linuxsampler.org/documentation.html Focus of this first release was an adequate support of the Gigasampler format, including experimental support for the new Gigasampler v3 format. For a complete list what is already covered and what is not, check the features site [3]. [3] http://www.linuxsampler.org/features.html Planned next: * strong synthesis optimizations * support for further sampler formats * instrument database system * implementation of further control interfaces like OSC [4] * SMP and network cluster support * as ports to other OSs are already on the pipe, maybe a new name :P You might want to use QSampler [5] as convenient graphical frontend to LinuxSampler. You can get everything from the downloads site [6].

[linux-audio-user] Getting two sound cards to work in Debian sarge

by Mads Munch Hansen

Hi, I've been trying to get my two sound cards to work: an integrated SiS (S17012), and a SoundBlasterLive (EMU 10K1). Both were detected fine by alsaconf. But I am only able to get the SoundBlaster to play though XMMS, XMMS says it's at hw:1,0, where the SiS is at hw:0,0. there is also antoher entry in the XMMS ALSA configuration that says "Sound Blaster Live!: EMU 10k1 FX8010 (hw:1,3)" Have no idea why that is there.. Also, GNOME has aprantly switched over to using OSS, (I can see this in the volume controlls) how can I change this to alsa? Any help would be apperciated! :) -- Mads

[linux-audio-user] Castblaster clone

by Mark Constable

Is anyone aware of what might be the best open source audio mixing package to start hacking something like the Castblaster that is aurally (partly) described where ? http://homepage.mac.com/dailysourcecode/DSC/DSC-2005-04-25.mp3 Any hints to shorten the devel cycle for a project like this would be gratefully appreciated. I'm chasing up some funding to hopefully subsidise a developer if one wants to get involved. No, tweaking PD is not my idea of getting aunt tillie into podcasting on linux, she needs a lightbulb that "just works" :-) --markc

[linux-audio-user] ANNOUNCE: QSynth 0.2.3 released!

by Rui Nuno Capela

Hi, After a long time laying in the backyard, QSynth 0.2.3 is being released to the world :) Qsynth is a Qt GUI front-end application to the excellent fluidsynth soundfont2 engine. You can check it out, right away from: http://qsynth.sourceforge.net The fine print goes like there's no really big new features on this. After all its only a minor dot-realease. As you may find from reading the changelog, there's a: - New option for system tray icon and menu, which is known to be effective on KDE enabled desktops; support for freedesktop.org's system tray protocol specification has been included so this maybe also effective on Gnome2. - Setup options for alternate MIDI and Audio devices were introduced. - Output level meters get smoother and slightly layout optimized. - Set to ignore the SIGPIPE ("Broken pipe") signal, where available, as the default handler is usually fatal when a JACK client is zombified abruptly. - Messages window limit is now enforced only when the line count exceeds in one third the user configured line count maximum; if Qt 3.2.0+ is in use, the QTextView widget is otherwise set to the optimized Qt::LogText format. - Updated Mac OS X build instructions (README-OSX, by Ebrahim Mayat). That's it. Enjoy! -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

[linux-audio-user] CLI mixer for envy24 cards?

by Edward Barrow

I've got a Terratec DMX 6-fire card (ice1712/envy24 chipset) running in a headless box with no X; I control it from the commandline over ssh. Does anyone know if there is a way of running envy24control without X? or is there a commandline mixer that has the same capabilities? Or even some comprehensive documentation for amix? the man pages are fairly cryptic. Specifically, the problem is that I can't persuade the front panel phono input to accept a stereo signal; amix is convinced that it's mono. -- Edward Barrow

[linux-audio-user] LADSPA hints

by tim hall

I wonder if anyone could suggest some useful settings for a couple of plugins. I'm working with Ardour right now. I want to use SC4 to essentially 'flatten out' a vocal take. I know such approaches are generally frowned on around here, but the take has a large dynamic range and it simply won't sit right in the mix any other way. I'm really not sure where to put the threshold and compression ration to achieve this kind of effect and I could do with some guidelines on attack, decay and knee settings. It's a pop song, and yes I really do want it to sound like that. any ideas? The other issue is stereo reverb. What I want is a little pre-delay followed by a long _smooth_ tail. Putting freeverb across the master track inputs just sounds like I dropped the band in a bucket. There must be a way of doing this. Would it be the way to make a separate stereo track for the reverb? I notice some plugins don't have any signal mix control. I have also noticed that many of the TAP plugins make bad broken noises in Ardour, should I not be using them in this environment? Any thoughts, experiences, pointers etc. gratefully received. I reckon I'll be posting some oggs up soon at this rate. ;) cheers, tim hall http://glastonburymusic.org.uk

Does the box you command it from have X? You could then open the envy24mixer from the remote machine to the X server running on the "client". To enable X11 forwarding from the ssh client do: ssh -X user@host You might need to enable X11 in the server sshd config, in debian: add or uncomment the line: X11Forwarding yes in /etc/ssh/sshd_config Sampo

I think someone else reported segmentation faults during file open and sent Paul a useful backtrace. If you have the exact same problem I'd expect a fix soon. ron > QJackctl : "cannot read event response from client > [ardour] (Resource > temporarily unavailable) > bad status for client event handling (type = 5) > cannot write request result to client > could not handle external client request > unknown source port in attempted connection > [ardour:auditioner/out 1]" > > > (I did sent this also to ardour users list) > Yahoo!

[linux-audio-user] how to change the bitrate of a wav file?

by Kenneth Dombrowski

Hi All, I have a wav file which cdrecord is rejecting, I believe because it is 24 bit rather than 16; here is the output from 'file': taylor_oxley_dixon.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 24 bit, stereo 44100 Hz Would someone be kind enough to tell me the command to convert this file to 16 bit, please? The sox manpage has only confused me. I did try: $ sox taylor_oxley_dixon.wav taylor_oxley_dixon.cdr sox: Failed reading taylor, oxley and dixon.wav: Sorry, don't understand .wav size Thanks in advance, Kenneth
