BpmRubato

streaming mode | Rhythm category

Inputs

  • beats (vector_real) - list of detected beat ticks [s]

Outputs

  • rubatoStart (vector_real) - list of timestamps where the start of a rubato region was detected [s]
  • rubatoStop (vector_real) - list of timestamps where the end of a rubato region was detected [s]
  • rubatoNumber (integer) - number of detected rubato regions

Parameters

  • longRegionsPruningTime (real ∈ [0, ∞), default = 20) :
    time for the longest constant tempo region inside a rubato region [s]
  • shortRegionsMergingTime (real ∈ [0, ∞), default = 4) :
    time for the shortest constant tempo region from one tempo region to another [s]
  • tolerance (real ∈ [0, 1], default = 0.08) :
    minimum tempo deviation to look for

Description

This algorithm extracts the locations of large tempo changes from a list of beat ticks.

An exception is thrown if the input beats are not in ascending order and/or if the input beats contain duplicate values.

Quality: experimental (non-reliable, poor accuracy).
