Chromaprinter

standard mode | Fingerprinting category

Inputs

  • signal (vector_real) - the input audio signal

Outputs

  • fingerprint (string) - the chromaprint as a base64-encoded string

Parameters

  • maxLength (real ∈ [0, ∞), default = 0) :

    use the first ‘maxLength’ seconds to compute the chromaprint. 0 to use the full audio length [s]

  • sampleRate (real ∈ (0, ∞), default = 44100) :

    the input audio sampling rate [Hz]

Description

This algorithm computes the fingerprint of the input signal using Chromaprint algorithm. It is a wrapper of the Chromaprint library [1,2]. The chromaprints are returned as base64-encoded strings.
