Hi Kartik, 1. As mentioned already, Mixxx has an option in the Analyze preferences to select whether to assume a constant tempo. However, this could use a lot of improvement. When a constant tempo is not assumed, the tempo fluctuates wildly, even if it's only within a range of ~.05 BPM and the BPM is actually constant. Using features like sync and loops with lengths defined by a number of beats with a wildly fluctuating tempo is odd. It would be great if Mixxx could intelligently detect whether the BPM is constant or changing. It's not uncommon for a track to be at a constant BPM for a while, speed up or slow down, then settle at a different constant BPM. Mixxx currently doesn't handle this very well; either it detects a BPM that is always changing or an average for the whole track that isn't accurate. I'm not quite sure how to go about this; my first guess would be to watch the second derivative of the BPM over time. Personally this is what I'd find most useful of the ideas you've suggested. I don't think it would be very easy to do it well.
2. This would sure be nice and has been suggested many times before. I'm not sure it would be a big enough project for GSoC though. See these feature requests: https://bugs.launchpad.net/mixxx/+bug/673515 https://bugs.launchpad.net/mixxx/+bug/1474621 You may also be interested in some of the other features on this Launchpad blueprint: https://blueprints.launchpad.net/mixxx/+spec/cuepoints-2.0 3. The goal if this is rather ambiguous and subjective. And as RJ mentioned, it's too big of a project for GSoC.
