get_window¶

paddle.audio.functional. get_window ( window: Union[str, Tuple[str, float]], win_length: int, fftbins: bool = True, dtype: str = 'float64' ) → paddle.Tensor [source]

Return a window of a given length and type.

Parameters

• window (Union[str, Tuple[str, float]]) – The window function applied to the signal before the Fourier transform. Supported window functions: ‘hamming’, ‘hann’, ‘gaussian’, ‘general_gaussian’, ‘exponential’, ‘triang’, ‘bohman’, ‘blackman’, ‘cosine’, ‘tukey’, ‘taylor’.

• win_length (int) – Number of samples.

• fftbins (bool, optional) – If True, create a “periodic” window. Otherwise, create a “symmetric” window, for use in filter design. Defaults to True.

• dtype (str, optional) – The data type of the return window. Defaults to ‘float64’.

Returns

The window represented as a tensor.

Return type

Tensor

Examples

>>> import paddle

>>> n_fft = 512
>>> cosine_window = paddle.audio.functional.get_window('cosine', n_fft)

>>> std = 7
>>> gaussian_window = paddle.audio.functional.get_window(('gaussian',std), n_fft)
