Istft

class ansys.sound.core.spectrogram_processing.Istft(stft=None)

Computes the inverse short-time Fourier transform (ISTFT) of a signal.

Class instantiation takes the following parameters.

Parameters:

stftFieldsContainer, default: None

DPF fields container containing a short-time Fourier transform (STFT) computed with the Stft class.

Methods

Istft.convert_fields_container_to_np_array(fc)	Convert a DPF fields container to a NumPy array.
Istft.get_output()	Get the ISTFT resulting signal as a DPF field.
Istft.get_output_as_nparray()	Get the ISTFT resulting signal as a NumPy array.
Istft.plot()	Plot signals.
Istft.process()	Compute the ISTFT.

Attributes

Istft.stft

Input short-time Fourier transform as a DPF fields container.
