java.lang.Object at.ofai.music.beatroot.Induction
class Induction
Performs tempo induction by finding clusters of similar inter-onset intervals (IOIs), ranking them according to the number of intervals and relationships between them, and returning a set of tempo hypotheses for initialising the beat tracking agents.
Field Summary | |
---|---|
static double |
clusterWidth
The maximum difference in IOIs which are in the same cluster |
static boolean |
debug
Flag to enable debugging output |
static double |
maxIBI
The maximum inter-beat interval (IBI), i.e. |
static double |
maxIOI
The maximum IOI for inclusion in a cluster |
static double |
minIBI
The minimum inter-beat interval (IBI), i.e. |
static double |
minIOI
The minimum IOI for inclusion in a cluster |
static int |
topN
The maximum number of tempo hypotheses to return |
