It was great to know that mood detection is going to be avaliable in future
release of mixxx. Please let me know if i could also join that
development. My plan is to use hierachical music mood detection algorithm
Based on thayer's mood model. I don't expect it to be perfect detection but
it would certainly give good start to the task. After implementing this i'm
planing to develop the algorithm later from the feedback of the users. I
don't know if this is a good summer project by considering the complexity
and other reasons. May be mixxx team can suggest me a good project for
gsoc20014 to make myself familiar with the interior of mixxx enviormnt.
Thanks a lot for pointing out practical limitations of my suggestion.
best regards,
Udara.
