Functions

SISDR(→ float)

Evaluate SI-SDR between two signals.

i_divergence(→ float)

spectral_smoothness(→ Tuple[float, float])

py2shpss.metric.SISDR(x: nptyping.NDArray[nptyping.Shape[*], nptyping.Floating], y: nptyping.NDArray[nptyping.Shape[*], nptyping.Floating]) → float[source]

Evaluate SI-SDR between two signals.

Parameters:

  • x ([float] or numpy.array) – a signal

  • y ([float] or numpy.array) – another signal

Returns:

SI-SDR between x and y

Return type:

float
