I am working on a android audio project which requires BPM tracking. I decided that writing my own would not be a good idea and after looking around, I found a few libraries that does BPM tracking such as aubio, vamp, echonest etc. Out of the lot aubio seemed a good choice. The problem is I cannot find good documentation that can help understand how I can use the library, such as, what sort of input audio formats are compatible (should i pre-process the audio before passing it to the function), etc.
Can you point me to some documentations or implementations of aubio to some open source projects (on android would be a bonus).
If you think there is an easier way (another algorithm/library) to port on android (preferably in c), let me know.
Thanks.
I used the make files provided with aubio to cross compile it for android. I followed some tutorials such as this which shows how to cross compile open source libraries. As for the documentation for aubio, i just used it several times to understand how it works (i studied how the examples worked) and read the phd thesis of the author to get a rough idea on the technical stuff.
