Default BPM Counter

Hi, is possible to build an audioinput -> BPM Counter?
I have already downloaded the WDL SDK and in the IPlugEffect.cpp i can see this three lines:

Code:
//double samplesPerBeat = GetSamplesPerBeat();
//double samplePos = (double) GetSamplePos();
//double tempo = GetTempo();
after browsing source code i know that the GetTempo() function give me only the project host BPM.

So, I think that my only way to do my work is to use an external library, like Soundtouch

Maybe someone can give me some explanation or some suggestions

ps: Is there a "GUI part"?

If you build a clean and reliable BPM counter that works inside REAPER as a VST or JS effect I will worship you as a god.

XD. Well, i know that there are a lot of BPM Detection apps and only one is vst but it is badly made and don't work for me.

One of the common problems in my studio is when customers come with a youtube downloaded beat. It's easy to match tempo by the built-in reaper function, but I want something like more automated and faster. Maybe a template track with this plugin *.*.

I want to build something like Logic BPM Counter, it's simply AWESOME.

It should be doable, but 'reliable' will probably highly depend on the type of source material. For four-to-the-floor techno it will be much easier than for, say, Charlie Parker.
