[Somewhat OT] Running QSC Venue Manager on wine ?

by fons＠kokkinizita.net

Hello all, Anyone managed to run QSC's Venue Manager software on wine ? <http://www.qscaudio.com/products/software/qscontrolnet/> Tried it yesterday - running the installer displays a message that it is checking for 'required Microsoft components' and that this could take 5 to 10 minutes. But it was still checking an hour later... But I'm a wine noob, so maybe I'm just missing the obvious... Ciao, -- FA There are three of them, and Alleline.

New mailing list for Android Audio Developers

by Olivier Guilyardi

Hi everyone! I am glad to announce the creation of the andraudio mailing list, dedicated to audio development on Android, at: andraudio(a)music.columbia.edu More info and subscribing: http://music.columbia.edu/mailman/listinfo/andraudio This list is meant to be a place to discuss about audio development, in the context of music and sound applications, but also games and other apps which use audio on Android. Discussions and questions about both Java and native APIs are welcome. In addition to application-level topics, we are interested in discussing about Android audio system internals, for educational purposes, as well as finding new ways to work with sound on Android. So please come and join us if audio development on Android interests you. -- Olivier

[LAA] [ANN] guitarix released gx_head

by hermann

I'm happy to announce the first public release of gx_head. gx_head is a simple guitar mono tube amplifier simulation based on the work we have done in the guitarix project. gx_head provide 3 tube models (12AX7, 12AU7, 6V6) and 8 different tonestack models(Bassman, Twin Reverb, Princeton, JCM-800, JCM-2000, M-Lead, M2199, AC30), so you can simply create the amp-model to your needs. gx_head comes with a bunch of in-build effects, like distortion, crybaby, autowah, phaser, flanger, echo, delay, . . . The effects could ordered in two Racks, on for the mono effects, witch could be load for pre or post processing, and one for the stereo effects, witch could only used in post processing. Effects are loadable over the menu, a pop-up menu in the racks, or a plugin bar. Settings could saved/load as presets. gx_head comes with some factory settings provided by guitarix/gx_head friend "funkmuscle", thanks therefore. All UI controllers could connected with jack midi via MIDI learn with your external MIDI controllers. gx_head is ready for language support via gettext() and comes thanks to Pablo Fernández with a Spanish translation. The style file gx2 is contributed by zettberlin, thanks Hartmut some features in short: * 8 tonestack models * 3 tube models * cabinet impulse response module * bass boster * easy Impulse Response file support via zita-convolver * on the fly IR-file resampling via zita-resampler * Oscilloscope and tuner * multi band distortion model * scalable EQ * phaser, flanger, stereo delay, stereo echo, * overdrive, compressor, freeverb, reverb, * chorus, moog filter, low/high pass filter, . . * MIDI learn * Patch Info widget * Preset File Load/Export option * factory settings * language support * shining User Interface via GTK/gtkmm * . . . . have fun _________________________________________________________________________ gx_head is licensed under the GPL. screenshots: http://sourceforge.net/apps/wordpress/guitarix/ direct download: http://sourceforge.net/projects/guitarix/files/gx_head/gx_head-0.12.0.tar.b… download: http://sourceforge.net/projects/guitarix/ please report bugs and suggestions in our forum here: http://sourceforge.net/apps/phpbb/guitarix/ ________________________________________________________________________ For extra Impulse Responses, gx_head uses the zita-convolver library, and, for resampling we use zita-resampler, both written by Fons Adriaensen. http://www.kokkinizita.net/linuxaudio/index.html We use the marvellous faust compiler to build the amp and effects and will say thanks to : Julius Smith http://ccrma.stanford.edu/realsimple/faust/ : Albert Graef http://q-lang.sourceforge.net/examples.html#Faust : Yann Orlary http://faust.grame.fr/ ________________________________________________________________________ For faust users : All used Faust dsp files are included in /gx_head/src/faust, the resulting .cc files are in /gx_head/src/faust-cc The tools we use to convert (post-processing and plot) the resulting faust cpp files to the needed include format, stay in the /gx_head/tools directory. ________________________________________________________________________ regards guitarix development team

ALSA multi plugin and JACK xrun callbacks

by Lee Azzarello

Hello, I'm looking for some advice for an interesting symptom of putting my M-Audio Fast Track Pro USB sound card into ALSA multi mode. This sound card has four physical outputs which are mapped to two 2 channel ALSA streams rather than one four channel stream. I used the ALSA multi plugin to combine these two streams into a single pcm device so JACK can interface with all four outputs. It is working nicely. Despite no perceptible problems in sound quality or latency, jackd is printing hundreds of XRUN callback warnings to the message console each second! I can operate the system perfectly fine, run multiple applications, connect them to the four virtual outputs with no audible timing issues. What is the meaning of this many XRUN callbacks per second? What kind of performance will this impact if not sound playback? Thanks for your help, Lee Azzarello

Re: [LAD] [LAU] [ANN] IR: LV2 Convolution Reverb

Technically, an impulse response is just an ordinary soundfile. Of course it has a certain soundfile format, sample format, channel count and samplerate, but if these are compatible with the convolution reverb you're loading it into (you can successfully load it into the plugin) then yes, it should generally work. Of course there are proprietary convolution reverbs that are bundled with impulse responses in a proprietary format, meaning that these impulses are not plain soundfiles, but are in some proprietary (and secret) binary format. Naturally, you cannot use those (and I guess if you could somehow reverse engineer the impulses into an "open" soundfile format, which would technically allow you to use the impulses in an open source plugin, the EULA of that plugin's license would have a word about it).
