[Android|OT?] CamSynth - Just an experiment

by Florian Paul Schmidt

Hi, I don't know if this is on-topic or off-topic - technically it runs on a linux, but then, maybe, just, no, no Android on LAD?? :D But anyways: I played a little with Android Development and hacked up a little experimental Synthesizer app. https://github.com/fps/android_camsynth https://play.google.com/store/apps/details?id=io.fps.camsynth It's free and open source and renders 8 voices (on my LG-P500) with a trivial (and wrong :D) synthesis method where the voice gains are determined by the camera image at a 8 x 8 px resolution.. I guess it's somewhat a minimal project which can be instructive to some (the synthesis part is implemented in C via JNI). And the code is very small.. Have fun, Flo

Leslie and convolution

by Julien Claassen

Hello everyone! I have just asked myself, if it is a good idea to use an IR of a Leslie for simulating a Leslie. Correct me, if I'm bloody stupid, but working on the basics of convolution, it doesn't look promising. Since you take the IR of the Leslie and then apply the full IR to each sample, meaning, that you might get more of a whirling reverb? Or is there another technique, to apply an IR and cycles. Just one "sample" of the IR to one sample of the input signal. If I am completely wrong, a simple no will suffice. My knowledge of this is basic. I've only got some knowledge from a lecture called "signal theory' to back me up and it should probably be called "an introduction to" or "basics of" at that. :-) Warm regards Julien =-=-=-=-=-=-=-=-=-=-=-=- Such Is Life: Very Intensely Adorable; Free And Jubilating Amazement Revels, Dancing On - FLOWERS! ====== Find my music at ====== http://juliencoder.de/nama/music.html .....................................

"It's beyond the pale that we today have all the communication technology Gene Roddenberry (August 19, 1921 – October 24, 1991) just could dream about, but the way it could be used today is weak." +1000. I would not say I am against Twitter, rather against all those patents and copyrights that just keep us in the dark ages of digital technology.

samples/symlinks/sessions

by James Morris

Hi, My sampler app has Non Session Mangement implemented but is currently still referring to external files by their original path. I want to use the symlink method as discussed fairly extensively here but I'd like to know if there is any recommended strategy for naming the symlink of a sample. It could so happen that as far as the filesystem is concerned the only discerning uniqueness between two samples is in the path (ie kit1/snare1.wav and kit2/snare1.wav). I've come up with three possible solutions to this (in my current order of preference): 1) symlink-to-sample created in a subdir named using a hash* of the full path to external file 2) painstakingly re-create the full path within the session dir and add the symlink into that. 3) some horrible text manipulation of the full path (ie replace / with _) that is bound to fail. * J. Liles mentioned SHA1 here: http://linuxaudio.org/mailarchive/lad/2012/3/30/189343 Are there other/better options or disagreements about (1) being a good choice over the other options I've presented? cheers, james.

Re: [LAD] setBfree - Fast Leslie is weird...

by Robin Gareus

Hi Fons, I've taken this to LAD, since it's not really a user issue.

Could it be that you've also accidentally sent other MIDI-CCs to setBfree that changed the Leslie's behaviour? The wobble (wrong octaves?) is not unexpected for two independent doppler-shifts and is also present in the real thing(TM). Yet, the Lesie is currently indeed the weakest link in the whole emulation. You're correct in saying that it is wrong. Yet, IMHO it still does sound OKish. It's implemented as a combination of angular dependent IR - measurements of the horn made at CCRMA [1] - which are also [incorrectly] used for the baffle. Plus the optional static IR to add the [feel of the] cabinet - which is also wrong, buts sounds good nonetheless :) - I'm hopeful that we'll get our hands on the IR measurements made for [2] which will make this 2nd stage obsolete. The acceleration is also not [yet] correctly implemented. I'm about to fix this with information provided in [2]. Even though it does sound kind of weird. I prefer it to the mdaLeslie or similar effects which are far too clean. YMMV. Your criticism is just and appreciated. Please bear with us - I suppose that we'll eventually end up rewriting the effects which carry a lot of legacy code. -- If you can spare the time a DSP expert like yourself would be very welcome. Anyway, one step at a time, robin [1] https://ccrma.stanford.edu/~jos/doppler/dafx02.pdf [2] http://www.aes.org/e-lib/browse.cfm?elib=15120

xfmr-plugins-0.0.1

by John Rigg

xfmr-plugins-0.0.1 has been released. At present it contains one LADSPA plugin, an anti-aliased transformer distortion emulator intended to be used on the master bus when mixing in a DAW such as Ardour. I made it for my own use, in order to get closer to the sound of an analogue mix without the extra round trip through the DA-AD converters. Hopefully others may find it useful. License is GPL v2. More details and download link here: http://www.jrigg.co.uk/linuxaudio/xfmr-plugins.html John
