[CLAM] How to estimate swing ratio? (with TickExtractor example perhaps?)

[David Garcia Garzon]

TickExtractor is MTG/UPF IP but raytracing (and most spatialization plugin code) is Barcelona Media IP.

While raytracing is non-relased code and we offer alternatives to enable or disable it. TickExtractor is a selfcontained program as we received it from the MTG. I knew that MTG had propietary processings to compute and modify the swing and i thought they were included in the opened code because i saw Swing related processings, but they are just swing compensation processings. Maybe compensating includes computing, but it is not in the generated xml file. A closer look to the code might put light on that.

The original author of that code is Fabien Gouyon. He should know why some code is included here or not, and could provided related papers that explain the algorithm if you want to contribute them to CLAM.

Hi David,

I experienced some confusion a while back about a few examples contributed by MTG staff (well, if I recall correctly it was MTG) which would not function because they were dependent on processings which were dependant on a proprietary raytracing library which MTG has yet to release to the public due to some kind of IP issues. I suppose it is possible that the code you are working with suffers from a similar dependancy, or the same one, and it may be worth your time to contact MTG to ask about that.

I should warn you, I am completely speculating on this matter, because I know little about the tick extractor section of CLAM.

Hi.

Yes, it seems you are right. I thought that TickExtractor, contributed by UPF's MTG, included their swing ratio. But i cannot find that either. I will dig more on that.

David.

Hi,

In the CLAm faq states that "CLAM provides tools to extract the tick,
the meter, the tempo and the swing ratio. " As I am very interested in
estimating the swing ratio I've been looking through the documentation
and source, but have not found any function that estimates swing
ratio.

In the examples folder there is a program TickExtractorExe that
extracts beats and ticks from an audiofile, can this be used to
extract the swing ratio? The documentation mentions that
TickExtractorExe can be given an configuration file but there is no
documentation regarding the format of that file...

I would be much grateful for any help in this matter!
