mel_to_hz¶

paddle.audio.functional. mel_to_hz ( mel: Union[float, paddle.Tensor, paddle.base.framework.Variable, paddle.base.libpaddle.pir.Value], htk: bool = False ) → Union[float, paddle.Tensor, paddle.base.framework.Variable, paddle.base.libpaddle.pir.Value] [source]

Convert mel bin numbers to frequencies.

Parameters

• mel (Union[float, Tensor]) – The mel frequency represented as a tensor with arbitrary shape.

• htk (bool, optional) – Use htk scaling. Defaults to False.

Returns

Frequencies in Hz.

Return type

Union[float, Tensor]

Examples

>>> import paddle

>>> val = 3.0
>>> htk_flag = True
>>> mel_paddle_tensor = paddle.audio.functional.mel_to_hz(
...     paddle.to_tensor(val), htk_flag)
...
