NEWB question - which is the best audio platform to develop an OpenSource project for?

by j o

Hi all, Sorry for the annoying NEWB question I'm starting an opensource project for a softsynth I'd like to make it portable as possible so I'm using g++ I tried googling around for about two weeks now and can't really make up my mind OSS/ALSA/JACK/PORTAUDIO etc... they all look like they have their pros and cons I need : * lowest latency possible (latency kills!) * easy development (I'm a decent coder) * portability (preferably other os's as well - os/x or even god forbid win) * Nice to have - easily deal with many different (standard) audio cards without actually having to develop drivers for them I've looked at the code of some very cool OS softsynths and I each has it's own choice What would you guys recommed? Thanks Jonathan

Guitarix as SC plugins

by hermann

Hi Today I receive a message from Bernardo Barros, he have ported the core dsp code from the Guitarix Project to make SuperCollider plugins out of each Guitarix effect/amp module. May it is of some interest for SuperCollider users here. https://github.com/smoge/gxplugins regards hermann

[LAA] [ANN] guitarix update release gx_head-0.13.0

by hermann

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 friends "funkmuscle" and "zettberlin", thanks therefore. All UI controllers could connected over 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 Spanish , and thanks to Ivan Tarozzi with Italian translation. The style file gx3-dezert is contributed by zettberlin, thanks Hartmut new features in short: * add mix tubes * add post amp * add noise gate * add Italian translation by Ivan Tarozzi * add desert skin by zettberlin * add factory settings by zettberlin have fun _________________________________________________________________________ gx_head is licensed under the GPL. screen-shots and sound examples: http://sourceforge.net/apps/wordpress/guitarix/ direct download: http://sourceforge.net/projects/guitarix/files/gx_head/gx_head-0.13.0.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-generated 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

jack plugin

by kallipygos＠inbox.lv

Hi Developers. I have more as one sound players on my system mplayer, vlc, qmmp ... Each of em uses jack output , for example 2 independent instances of mplayer mplayer -ao jack  -srate 16000 '/home/alf/mp3/mettwoch-de-doof-nuss.mpa.mp2' mplayer -ao jack  -srate 16000 '/home/alf/mp3/effeckt006.mp3' So far everything is excellent. How i do write my own DSP plugin for jack ? I wanna use my DSP plugin at this point, where all input channels are mixed together . How my plugin can ioctl() detect current samplerate, endianess, nr channels, samples interleaved or not, ... and maybe some more stream parameters. How do compile jack plugins ? What #include-s  must be used ? If my plugin will grow, and eat more and more CPU, how i prevent x-runs ? Is somewhere _simple_ C example how i can write jack plugins ? In simplest case - what is minimal program where i do each sample divide by 2 ( or for 16bit short type just  shift  sample>>1 ) Tnx in advance. Alf ----

Re: [LAD] Meego pulseaudio "compliance" and "enforcement" (was Re: [Meego-handset] Enabling Speakerphone)

by Niels Mayer

FYI, here's an example of the kind of app that needs to have good audio performance on a handset: http://www.youtube.com/watch?v=bwqflVX5oNo http://www.warmplace.ru/soft/sunvox/ ( http://lists.linuxaudio.org/pipermail/linux-audio-user/2010-December/074828… ) It has decent performance on maemo and appears to use pulseaudio, which eats 1/3 of the CPU of the 'sunvox' process. The sunvox application appears to have a UI thread and a worker thread each consuming about 1/2 of the 35% CPU load of the app. Mem: 238432K used, 7108K free, 0K shrd, 3396K buff, 67580K cached CPU: 52.2% usr 7.8% sys 0.0% nice 39.8% idle 0.0% io 0.0% irq 0.0% softirq Load average: 0.99 0.45 0.16 PID PPID USER STAT RSS %MEM %CPU COMMAND 1916 1162 user S 6388 2.5 35.1 /usr/bin/sunvox 825 1 pulse R < 3812 1.5 12.1 /usr/bin/pulseaudio --system --high-priority 897 730 root S < 16524 6.7 9.6 /usr/bin/Xorg -logfile /tmp/Xorg.0.log -logverbose 1 -nolisten tcp -noreset -s 0 -core Doing an "ls -lR /" in a remote xterm (over SSH) results in some audio glitching, but no "desynchronization" where the audio just stops playing. -- Niels.

I didn't realize that the gst-plugins-soundtouch plug-in package did not exist in Gentoo as part of the gst-plugins-bad package. One that was installed i was able to get it all working. Bearcat M.

I tried my usual torture test on gst123 0.1.4 and it's still having the same problem on the KCRW live stream, which IMHO stems from some kind of memory leak related to changing of program text (since other streams that don't change the program text don't seem to crash). The crashes happen after several hours of playing, usually after a new program text label is output on the stream. (note parsing oddities seen before a crash e.g. "Title : <HTML> Artist : " ). I ran the test by outputting to each of the stereo channels on an ice1712 soundcard, which allows for five simultaneous gst123 instances to run (see the end of

snd-usb-audio dying on jackd xruns

by Rods Bobavich

So I start jackd and it runs fine for a while. Then ALSA crashes and triggers an xrun. Jackd continues to do its merry thing - minus the part about spitting info out to my soundcard... I've tried multiple usb intefaces. All work fine with other computers. I've tried multiple version of Ubuntu with various versions of ALSA. Only this machine is affected. I have 3 other machines that run these interfaces just fine... So it seems to be a hardware compatibility issue not a software glitch in one version. I've tried many boot flags but to no avail. Am at a loss on how to troubleshoot. The machine is M4N75TD motherboard with a Phenom II 1055T and the latest bios flash. ...Rods ;-)

Audio Files: Bpm tagging

by Harry Van Haaren

Hey guys, I'm looking for the "lowest-common-denominator" of audio file formats that handle BPM info. Do programs like Ardour / Audacity / Mixxx write BPM info when exporting / analysing a file? Cheers, -Harry
