Hi Just realized that the LAC2010 is being held May 1-4, which translates into Saturday to Tuesday. Hmmm. Could it be that in fact it should be April 1-4, which is Tuesdag to Sunday? -- Atte http://atte.dk http://modlys.dk

jcgui-0.6 release

by hermann

Hi all, happy new year. I would announce a release of Jc_Gui. It's a little host wrapped around the fantastic convolution engine from Fons Adriaensen called jconvolver (zita-convolver) What is it for ? It's designed to search/load and run IR-*.wav files on a local machine with jconvolver. It include a settings widget, were gain, delay, min/max mem and mode can set and the used wave file and a part of it (offset/length) could choosed. Jc_Gui itself provide a Stereo Host, with master gain, tone (bass,middle,high)controllers, balance slider, and for the output to jconvolver per channel delay and gain controllers, and a wet/dry slider to mix the output from jconvolver with the original source. What isn't it for ? It's a 2 Channel thing only, you can't make multi channel settings with this jcgui. release 0.6 comes with following changes: * fix crash when multichannel(>2) files try to load * optimize GUI performance project page : http://jcgui.sourceforge.net/ download : https://sourceforge.net/projects/jcgui/ enjoy hermann

axonlib v0.0.0 - the pioneer axon

by cern

01.jan.2010 :: axonlib v0.0.0 :: the pioneer axon new year, new plugins, new framework, new plans, new ideas a full refresh/reboot, and a call for response, testing, contributions, etc.. ------------------------------ a single axon, <http://en.wikipedia.org/wiki/Axon> with all its branches taken together, can innervate multiple parts of the brain and generate thousands of synaptic terminals. axon guidance <http://en.wikipedia.org/wiki/Axon_guidance> (also called axon pathfinding) is a subfield of neural development concerning the process by which neurons send out axons to reach the correct targets. axons often follow very precise paths in the nervous system, and how they manage to find their way so accurately is being researched. pioneer axon <http://en.wikipedia.org/wiki/Pioneer_axon> is an axon that lays down initial growing path for the axons of other neurons to follow. ------------------------------ current features: - c++, free, opensource, .. - cross platform (inux/win32) - cross compile (gcc, mingw, cygwin?) - small/tiny (around 100kb (uncompressed) for a plugin) - standalone/vst - with or without gui (x11/gdi, double buffered, low/medium-level gfx primitives) - hierarchy, window, container, widget, canvas, surface, bitmap, png, .. - simplified vst: - create a plugin with just a few lines of code (usually just one cpp file) (override doProcessMidi/Parameter/Block/Sample/State/Transport/CreateEditor.. etc) - the dll/so stuff (you can forget all about it, handled internally) - host sync, transport state changes - voice manager (for polyphonic synth) - parameter/widget connection - editor (layered on top of base vst handling) and a lot more smaller things i probably forgot.. work in progress / partially implemented / coming: - simplified compilation (scripts, batch files, ide-setup) - programs/banks - dsp-graph / modular - fill in the missing bits and pieces, tie up the loose ends - tcc, embedded c-compiler (capable of compiling the linux kernel, use external dll's etc) - fft, goertzel, transients, wavelets (daubechies, haar) - cellular automata - optimizations, simplifications todo: - alpha blending/transparency (especially x11) - opengl? - ladspa/dssi/lv2 (linux) - neural networks - more optimizations, simplifications goals: - playful audio exploration and experimentation - thinking outside of the box - being different for the sake of being different wanted: - (alpha/beta-) testers - ideas, thoughts, comments - contributions - especially for the platform specific stuff not wanted: - highbrow, academic, know-it-all, politically/religious correct, rules or dogmas current plugins (src & .dll/.so): - ana_sigview (signal viewer/oscilloscope) - fx_blur (delay/blur) - fx_cutter (beat synced cut/repeat slices) - fx_dist (distortion) - fx_dynamics (dynamics, compressor) - fx_envelope (midi controlled audio envelope) - fx_freeze (freeze/repeat audio slices) - fx_grains (grain cloud/delay) - fx_moddelay (modulated delay, flanger/phaser/chorus) - fx_split (frequency band splitter) - fx_svf (state variable filter) - fx_tempodelay (host sync delay) - fx_waveshaper (waveshape/distort) - fx_wgtavg (weighted average/lp) - midi_ccaudio (midi cc -> audo) - midi_fibonacci (fibonacci note generator) - midi_notelen (midi note length controller) - midi_syncdelay (delay midi until next x beat/bar/..) - midi_transpose (midi note transpose) - syn_binaural (binaural beats generator) - syn_perc (lofi/glitchy percussive synth) - syn_plucked (plucked string) - syn_poly (polyphonic synth) ported plugins: - autotalent <http://web.mit.edu/tbaran/www/autotalent.html> (pitch tracking/correcton, ala autotune) - freeverb liteon <http://neolit123.blogspot.com/>: - liteon_lofi - liteon_tilteq new plugins added almost daily! some of these might not be proper, finished plugins in the normal sense, at least not at the moment, but more like examples, tests, prototypes, or perhaps starting points for your own plugins, ... but they will grow and expand, getting new features and bugfixes as needed (or requested).. so feel free to give suggestions, thoughts, ideas.. ------------------------------ more info: - google code hosting <http://code.google.com/p/axonlib/> - ccernn.audio <http://sites.google.com/site/ccernnaudio/> - ccernn <http://cernthskei.wordpress.com/> excuse my non-perfect english if something looks/sounds weird or wrong, ask, don't just assume and, yes, there are probably some mental conditions running amok here. medication could help :-) - ccernn also, some clarifications about the legal/license issues with a combination of (l)gpl and the vst sdk would be appreciated..
