LoopBpmEstimator

streaming mode | Rhythm category

Inputs

  • signal (vector_real) - the input signal

Outputs

  • bpm (real) - the estimated bpm (will be 0 if unsure)

Parameters

  • confidenceThreshold (real ∈ [0, 1], default = 0.95) :
    confidence threshold below which bpm estimate will be considered unreliable

Description

This algorithm estimates the BPM of audio loops. It internally uses PercivalBpmEstimator algorithm to produce a BPM estimate and LoopBpmConfidence to asses the reliability of the estimate. If the provided estimate is below the given confidenceThreshold, the algorithm outputs a BPM 0.0, otherwise it outputs the estimated BPM. For more details on the BPM estimation method and the confidence measure please check the used algorithms.
