arguyHey lv2ers!00:12
arguyI'm having toubles validating my ttl file00:12
arguyI get https://github.com/lucianodato/noise-repellent has no <http://usefulinc.com/ns/doap#name> values of type <http://www.w3.org/1999/02/22-rdf-syntax-ns#PlainLiteral>00:12
arguyDon't really know what I'm doing wrong00:13
arguyI included @prefix doap: <http://usefulinc.com/ns/doap#> .00:13
arguyand I'm using doap:name "Noise Repellent" ;00:14
arguyAnyone know what I might be doing wrong?00:17

* rgareus looks00:20
rgareusarguy: try defining a URI for yourself  and reference that (don't define doap:maintaine inline)00:21
rgareuse.g  https://github.com/x42/stepseq.lv2/blob/master/lv2ttl/stepseq.ttl.in#L18  and L2700:22
rgareusdoap:maintainer  needs to reference a foaf:person00:22
rgareusmaybe adding       a foaf:Person;      helps00:23
arguyrgareus, hmm no luck00:40
arguyI added doap:Project and that error started to show00:41
rgareusmmh it looks fine in git00:53
rgareusthe manifest seems to lack a  lv2:binary00:57
rgareushah01:02
rgareusarguy: in the manifest you define https://...01:02
rgareusarguy: inbut in the nrepel.ttl  http01:02
rgareusso lilv looks for https://github.com/lucianodato/noise-repellent   and does not find anything (the nrepel.lv2/nrepel.ttl  does not match)01:04
rgareusarguy: https://gist.github.com/609f29e92465f85b50d546e777543d9501:08
arguythank's robin!01:09
arguyIt's working now01:16
rgareusI'll delete that gist again, then01:17

arguyDoes ardour generic gui generation support trigger port property?01:46
arguyAudacity renders a button but ardour just renders a toggle button without the auto off behaviour01:47
rgareusarguy: there's no support for trigger in ardour, yet01:51
rgareusnor in jalv IIRC01:52
arguyOk no problem01:53
rgareusin suppose in ardour a push-button would imply "notAutomatic"  automation seems weird in that case01:53
rgareusarguy: for "learn" you do want a toggle anyway.   I suppose for "reset" a pushbutton would be handy01:55
arguyrgareus: Yes you are right01:58
arguyrgareus: I have to change that logic01:58
rgareusarguy: do you use ardour from ardour.org ?  it includes Harrison's XT-TG (demo) which has a custom GUI for "learn"01:59
rgareushttps://www.youtube.com/watch?v=l8Nbf2Jk3pg  (also a LV2)02:00
arguyrgareus: no I'm using falktx repos02:00
arguyrgareus: that thing is awesome02:01
arguyrgareus: I will do a gui but for now I have to finish the dsp part of it and make it as good as I can02:02
rgareusyeah one step at a time, I suppose02:04
arguyrgareus: yep. And since I'm not anything close to a profressional programmer this is not trivial for me02:07
arguyrgareus: I only knew that a denoiser was needed02:10
*** trebmuh has quit IRC02:13
rgareusarguy: I'm curious how it'll hold up.02:20
rgareusdenoisers are harder than hard.  it took iztope 10+ years of R&D for a usable product02:21
rgareusand a lot of tools just get stuck after spectal masking02:22
arguyrgareus: I know I read all the material I could find from alexey lukin the guy who did it02:22
arguyImpresive work02:23
arguyEven if I cant make it that great It's something02:25
arguyBetter than nothing02:25
rgareusthere's that, too02:25
rgareusand well, you gotta start somewhere.  who knows where it'll be in 10 years02:26
arguy:)02:26
rgareusizotope RX5 didn't appear over night, either02:26

rgareusarguy: re cross-platform Makefile  you may want to inspired yourself from e.g.  https://github.com/x42/testsignal.lv2/blob/master/Makefile17:31
rgareusarguy: change "fftw3" vs "fftw3f"  in the check,  and I suggest to separate LDFLAGS and LOADLIBES (because order does matter: flags must be before libs)17:32
arguyrgareus: thanks I will take a look later17:33
rgareusarguy: I've rolled a OSX binary for seablade17:33
rgareusjust the makefile needs some tweaks, the code is fine. well done17:34
arguyWell thanks robin. If you want to change anything let me know17:35
arguyI'm open to code and suggestions17:36
rgareusarguy: you really just need different LDFLAGS  for Linux vs OSX17:40
rgareus"-Wl,-Bstatic -Wl,-Bdynamic -Wl,--as-needed" is linux specific17:41
arguyYeah I saw that in your makefile17:42
rgareusthe OSX equiv is  -dynamiclib17:42
arguyDo you mind if i use your makefile as a base for mine?17:42
rgareusno, feel free to copy/paste17:42
arguyrgareus: thanks robin i will work on it later then17:43
rgareusXWIN is meant to be set to   x86_64-w64-mingw32  or i686-w64-mingw32    so in concat you get e.g.  i686-w64-mingw32-gcc  i686-w64-mingw32-ld  (standard names for the cross compiler)17:44

rgareusarguy: not sure when you ping timeed' out.17:58
arguyI was riding my bike to work and lost connectivity18:01
arguyI'm curious if the buffer extension would be a good fit for what I'm doing18:02
arguyIs it intended to work with fft buffers for example?18:02
rgareusit's only needed if  run()  requires a fixed block-size18:06
arguyHmm interesting18:08
rgareusif latency is not a problem: you can feed fftw as needed and process once the buffer is full.18:09
rgareusand decouple things by a ringbuffer18:09
arguyI'm doing that18:09
arguyIt would be interesting though to have a zero latency processor18:10
arguyI have to work in other things before that18:11
