hz_to_mel¶

paddle.audio.functional. hz_to_mel ( freq: Union[paddle.Tensor, float], htk: bool = False ) → Union[paddle.Tensor, float] [source]

Convert Hz to Mels.

Parameters

• freq (Union[Tensor, float]) – The input tensor with arbitrary shape.

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

Returns

Frequency in mels.

Return type

Union[Tensor, float]

Examples

>>> import paddle

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