Resample

streaming mode | Standard category

Inputs

  • signal (real) - the input signal

Outputs

  • signal (real) - the resampled signal

Parameters

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

    the sampling rate of the input signal [Hz]

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

    the sampling rate of the output signal [Hz]

  • quality (integer ∈ [0, 4], default = 1) :

    the quality of the conversion, 0 for best quality, 4 for fast linear approximation

Description

This algorithm resamples the input signal to the desired sampling rate.

The quality of conversion is documented in [3].

This algorithm is only supported if essentia has been compiled with Real=float, otherwise it will throw an exception. It may also throw an exception if there is an internal error in the SRC library during conversion.
