[ANN] ladspamm - a small c++ library for handling LADSPA plugins

by Florian Paul Schmidt

Hi, GIT repo: https://github.com/fps/ladspamm DOXYGEN docs (very minimal): http://fps.github.com/ladspamm For my own small side projects I needed a little c++ wrapper lib around LADSPA plugins. Since someone else might be interested in it, too, I put it on github. ladspamm::world world; ladspamm::plugin_instance instance( world.libraries[0]->plugins[0], 48000 ); instance.activate(); instantiates and activates the first found plugin in the first found library.. This is version 0.0.1 so expect bugs and missing features.. Have fun, Flo -- Florian Paul Schmidt http://fps.io

CAPS 0.9.3 and 0.4.6

by Tim Goetze

CAPS 0.9.3's guitar amplification contains four new tonestacks, distortion asymmetry dependent on output power and other sound improvements. The modulation of the mono chorus has been smoothened, and the Plate default parameters have been restored to be nearer the more reverberant response of the older versions. http://quitte.de/dsp/caps.html There's also a 0.4.6 release, stamped 'obsolete', containing all the plugins that were in 0.4.5 but did not make the cut to 0.9. There are no duplicate plugin IDs, and the library is differently named, so both versions can co-exist on one system. http://quitte.de/dsp/caps.html#Older_Versions

Proper detection and optional inclusion of jack/session.h has been added as well. AFAICT, this should take care of the last of the jack1 issues. Could you try the latest in v0.14.97-dev and let me know how it goes? Thanks! --ww

ANN: Audiality 2 1.9.0 - Refactored, renamed, rearmed!

by David Olofson

Audiality 2 1.9.0 - Refactored, renamed, rearmed! ------------------------------------------------- "Audiality 2 is a realtime audio and music engine, primarily intended for video games. While it supports traditional sample playback as well as additive, subtractive and granular synthesis, the distinctive feature is subsample accurate realtime scripting." Audiality 2 (previously released as ChipSound) is used for sound effects and music in the game Kobo II. The name originates from an old structured audio and sampleplayer engine, originally developed as part of the XKobo port Kobo Deluxe. The old engine is no longer maintained, so the new one, which has similar goals but much greater potential, is now inheriting the name. Key features: * Microthreaded realtime scripting engine * Modular voice structures * Subsample accurate timing * Designed for hard realtime applications * No hardwired voice/channel/bus structures * No hardwired "MIDI-isms" or similar * No hardwired instruments or songs - only programs * Lock-free timestamping C API * Audio I/O drivers: * SDL audio * JACK * Application provided drivers * System drivers: * libc malloc (soft RT) * Application provided drivers * Implemented in portable C * zlib license Official site: http://audiality.org/ Direct download: http://audiality.org/download/Audiality2-1.9.0.tar.bz2 Related; Kobo II site: http://kobo2.net/ -- //David Olofson - Consultant, Developer, Artist, Open Source Advocate .--- Games, examples, libraries, scripting, sound, music, graphics ---. | http://consulting.olofson.net http://olofsonarcade.com | '---------------------------------------------------------------------'

[LAA] Guitarix release 0.25.1

by hermann meyer

We are proud to announce the release of guitarix2-0.25.1 Guitarix is a mono tube amplifier simulation for jack, with additional mono/stereo effect racks witch can be filled with some in-build effects as well as with external LADSPA plugins. Download from http://sourceforge.net/projects/guitarix/ After having some discussions with David Robillard (thanks for your patience, David) I realize that I need to push out a update in order to avoid a possible violation of the LV2 specs, so guitarix2-0.25.1 is out, those how use the last V0.25.0, are strongly recommended to update. * GxAmplifier tube 12ax7 tonestack sovtek cabinet 4x12 * GxAmplifier-II tube 12AT7 tonestack soldano cabinet AC30 * GxAmplifier-III tube 6C16 tonestack bassman cabinet 1x15 * GxAmplifier-IV tube 6V6 tonestack soldano cabinet mesa * GxAmplifier-V tube 6DJ8 tonestack ampeg cabinet HighGain there are mono and stereo versions of those amps included in the bundle. Thanks goes to Richard Dalton from http://www.Ampskindesigns.com for given me permission to use (and distribute) his work within a GNU GPL project, many thanks Richard. thanks goes as well to David Robillard for his great work on the LV2 specs and to Rui Nuno Capela for implement them so excellent in qtractor. Please check it out and give feedback if you find a problem.

Libao and usb soundcards

by Muffinman

Hello all, I'm struggling a bit with getting libao to work in C on Debian (Squeeze, kernel 2.6.38.5, driver is Alsa). I've got this slightly modified test script and it seems to work fine on my internal soundcard (it opens the device and plays a test tone). However, when trying to do the same trick on an external USB-dac (tried two different models), it gives an "Input/output error". I've tried different settings, but as far as I can see there is not really that much to set (especially if it plays on one soundcard but not the other, dev=hw:1 should suffice). Does anyone have a suggestion on how to get this to work?

[ANN] CAPS 0.9.1

by Tim Goetze

CAPS 0.9.1 ========== The C* Audio Plugin Suite is a selection of popular effects, unique filters and generators. For the digital guitarist, CAPS offers a range of processors recreating the formation of tone in traditional instrument amplification. Beyond sound quality, central design considerations are latency-free realtime operation, modest resource demands and meaningful control interfaces. http://quitte.de/dsp/caps.html This release contains major improvements particularly in the area of guitar signal processing, notably in the AmpVTS and CabinetIV plugins. These are the first iterations of the Amp and Cabinet designs that their author is well and truly happy with. Also worth noting here is the Compress plugin, a completely new design featuring optional oversampled soft saturation/limiting. http://quitte.de/dsp/caps.html#AmpVTS http://quitte.de/dsp/caps.html#CabinetIV http://quitte.de/dsp/caps.html#Compress http://quitte.de/dsp/caps.html#AutoFilter All plugins have been subject to further development, speedups, refinement and polishing. In many cases, this has been accompanied by the consolidation of shared or duplicate functions into a single circuit; for example, the AutoFilter plugin now fulfills the roles of the old SweepVF and AutoWah units. Many obsolete plugins have been removed, and everywhere else, port names, layouts, value ranges, defaults etc have been changed as well. Upgrading from previous releases is encouraged nonetheless. Enjoy!

Multi-instance worked, but it was a pain. Currently, number of voices is set at compile time, so be sure to run configure with --enable-parts=4, or however may parts you want to use.

No more drifting arpeggios :) Unfortunately, I haven't got around to implementing LFO sync with the MIDI clock yet, so there still may be some drift. This MIDI clock currently handles event timestamping and MIDI/audio/engine thread synchronization, and does not yet handle phase sync. If you're running on a fast 64-bit processor, you can get better precision on the LFOs with a pure 64-bit build (--enable-cpu-power=4). > > This version is fully tested with Fedora 17 and 18, and should be just > > as trouble free on any Fedora >= 14 or CentOS >= 6.0.

Try v0.14.97-dev in git: git clone -b v0.14.97-dev https://github.com/williamweston/phasex.git I haven't been able to verify the jack1 fixes yet, but I'm very hopeful. Cheers, --ww
