torchaudio.functional.DB_to_amplitude¶

torchaudio.functional.DB_to_amplitude(x: Tensor, ref: float, power: float) → Tensor[source]¶

Turn a tensor from the decibel scale to the power/amplitude scale.

Parameters:

x (Tensor) – Input tensor before being converted to power/amplitude scale.
ref (float) – Reference which the output will be scaled by.
power (float) – If power equals 1, will compute DB to power. If 0.5, will compute DB to amplitude.

Returns:

Output tensor in power/amplitude scale.

Return type:

Tensor
