Chromaprinter
streaming mode | Fingerprinting category
Inputs
- signal (real) - the input audio signal
Outputs
- fingerprint (string) - the chromaprint as a base64-encoded string
Parameters
- analysisTime (real ∈ (0, ∞), default = 30) :
- a chromaprint is computed each 'analysisTime' seconds. It is not recommended use a value lower than 30.
- concatenate (bool ∈ {true, false}, default = true) :
- if true, chromaprints are concatenated and returned as a single string. Otherwise a chromaprint is returned each 'analysisTime' seconds.
- 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.
