====== Graph fast forward ====== | Authors | Vladimir Viro and Brian McFee | | Code | https://github.com/bmcfee/graffw | We implemented a "smart" fast-forward for audio playback that uses beat-level feature similarity to determine jump points for non-uniform accelerated playback. Given a target playback rate, the method builds a graph over beats in the song, where edges between beats (s, t) are weighted according to continuity (feature distance between t and s+1) and conformance to the acceleration rate. All shortest paths to the end of the song are computed, allowing the interface to quickly jump forward in the song. Note: this is still in progress, and we may not finish before demo time is over! This hack was conceived at 3pm on Sunday.
