[LAD] [LAA] gxtuner-1.6 update
Hello A update release of gxtuner is available a simple, small and lightweight guitar/bass tuner for jack (a break out of the guitarix tuner module) This update is for those, who's like to use a simple tuner with a analogue style like interface It resolve some user requests and primary added some more command-line options. Also it added all configuration options to be restored by the jack session manager. gxtuner-1.6 changes: * add command-line option reference pitch control * add command-line option threshold control * add command-line option window size * add command-line option window position * add all options to be restored by jack session manager gxtuner comes with a analogue like, full arbitrary scaling interface (scale), show the tune, the octave and the accumulated frequency in Hz, gxtuner comes with full jack-session support. gxtuner use a equal-tempered scale based on A4 = 440 Hz (427Hz - 453Hz) gxtuner is licensed under the GPL. for more information please read the included README file. get it here: http://sourceforge.net/projects/guitarix/files/gxtuner/ direct link http://sourceforge.net/projects/guitarix/files/gxtuner/gxtuner-1.6.tar.bz2/download have fun Guitarix developers ___ Linux-audio-announce mailing list linux-audio-annou...@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-announce ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev
Re: [LAD] Replaygain for video?

Have a look at https://www.ohloh.net/p/Samplecat it includes a ffmpeg audio decoder, max. gain calculation, Fons' ebur128 analysis and more.. Comment out the mime-type filter in main.c:788 to read the first audio track from a video file. https://github.com/avuserow/ffmpeg-replaygain seems to do what you want but requires ffmpeg av* libs =0.5 and/or a bit of patching. My ffmpeg is rather recent (2023) but the program doesn't build, so I guess it needs patching. Seems like my ffmpeg is too new. The implementation looks insanely complex to me. edit ffs.c replace CODEC_TYPE_AUDIO with AVMEDIA_TYPE_AUDIO and you are good to go with ffmpeg 0.5. For ffmpeg 0.5, replace the 'avcodec_decode_audio3() call with: int len = avcodec_decode_audio2(ffs-cc, (int16_t *) (buf + rdec), size, tmppkt.data, tmppkt.size) [..] I don't know any command-line apps to modify meta-data on a per track basis in-place (maybe ffmpeg can do that?), but the new liav* meta-data API is pretty nifty. Do you refer to http://www.libav.org/ ? Sorry, a typo slipped in. Yes, libavformat, libavcodec, libavutil, etc.. I prefer libav* from ffmpeg.org not the branch libav.org. Playback [..] A compressor plugin (for video-players that don't yet have one) would be much more useful in the real world because - purists won't care for neither replaygain nor compression Agreed, if purists are people who only watch professionally produced movies or similar. In such a case there'd be no need for it. - consumers will complain that replay-gain is not sufficient for long[er] films and won't care about sound-degradation by compression Why would it not be sufficient for longer films? It can't do anything to improve bad mixing, that's true, but there's not much one can do about that anyway (except maybe apply some eq to make dialogs understandable). The single loud explosion (show down) or a slammed door will dwarf all the all whispered (sexy) dialog. I just ran `fbff` (ffmpeg replay gain) on a The Great Dictator (1940), Clockwork Orange (1971) and Avatar(2009). as well as http://www.youtube.com/watch?v=f2bcPIXl8kc They _all_ came out on zero (Max PCM value found: 1.00, Title gain: 64.82). Looks like they have been normalized already. (maybe youtube and DVD master[er]s do that?!) But the dynamics are completely different. For comparison, ebur128 reported: Loundness-range 19.1 LU; Peak 6.7 LU for the Chaplin movie. and Loundness-range 11.3 LU; Peak 15.3 LU for the youtube video, (Quite good actually, RHCP's 'Around the world' only features a Loundness-range 4.0 LU; Peak. 19.2.) [..] It's a great educational project with many problems that one will encounter in other /real-world/ projects. Thank you very much for that, I fear that it might be too hard. Most students have very little coding experience. Most courses require little coding and that is mostly done in java. The course in question is a beginner C/C++ course and for many students this was the first experience with those languages. If you want to learn hands-on CS, don't study Informatics. Two years ago I taught the advanced programming class at the Kunst-universität Linz. 3rd semester *Art* school: 1/3 of the students were fluent with openframeworks openCV C++. The rest knew either JAVA/processing.org or Pure-data. I was pleasantly surprised. [..] Did you try http://www.akjmusic.com/software/jackctl20110317.py ??! I thought I knew them all... Thanks, this is great and pretty close to what I/we imagined. I don't fully understand the alsa midi mode, I think it doesn't use a pager for many ports and I guess a way to connect a range of ports to another would be useful as well, but it's really close to what I had in mind. Julien will be happy to hear about this. That pretty much takes care of this idea :) I think Aaron is on the LAD list. IIRC he announced it on LAU and LAA and may be willing to add a pager or other features. - just change the subject-line :) More detailed ideas exist thanks to Julien Claasen. - A simple but hopefully sane mplayer GUI RFTL. I sadly don't what that means :) AWW snap. ROFL. meaning: Mission impossible. Die Idee ist gut, die Welt noch nicht bereit. (Tocotronic) http://www.mplayerosx.ch/ :( It looks reasonably nice, similar to smplayer, but the devil is in the details. And this one seems to be for OSX only. That's why I'm sad. - A new GUI for ecasound Another problem I might have is that most students in the course are Windows users, not sure whether I can go solo. You can x-compile for windows and test with wine. ffmpeg is x-platform, as is mplayer and gstreamer. ..just be prepared to throw in a day or two to set up a x-platform

Yes good point, Perhaps writing the value in digit form inside the knob could work? See next point about making things a lot more shiny and cool :D Perhaps this a kind high-tech looking rather than plain old knobs and labels would be nice? I'm thinking more like so: http://lesitedeburnie.free.fr/big/micromodular.jpg Or perhaps http://justanothermobilemonday.com/Wordpress/wp-content/uploads/2009/08/IMG_0680-300x450.PNG for the wave type selection or so... Obviously the matrix routing that is out of the question here as it doesn't apply, I mean more the flavour of GUI. Or perhaps I'm getting a touch carried away here :) I really like both idea!

Re: [LAD] FFADO midi ports
I must be missing something here. amidi -l should list all midi out ports that are available to amidi, right? No matter what i try with a2j and all of its variants (including j2a and using the -e option) amidi -l never gives me any usable ports. Same results as root. Or should i be using the -L option to list the availabble ports? if yes, how does that work? I cant figure it out. :-( Another question: will a usb midi interface list the midi ports under alsa?

Thanks for the clarification. So let me correct that: The Great dictator DVD has an Integrated Loudness of 4.1 LU, Loudness Range 19.1 LU. and 'Music for one appart. and 6 drummers' from you-tube: Integrated Loudness: 12.9 LU, Loudness Range 11.3 LU Both are already normalized to 0 dbFS. Checking some more, revealed that you-tube does not actually normalize audio volume automatically: e.g. http://www.youtube.com/watch?v=hJMEvDu0K2E peaks at -16.5 dbFS Integrated Loudness: -1.7 LU, Loudness Range 9.9 LU Updates of ebur128 will show only the first two, unless you explicitly ask for the others as well.

Usually, you want to use the latter. Try aplaymidi -l. Another question: will a usb midi interface list the midi ports under alsa? Yes.
