mindspore.dataset.audio.Magphase
- class mindspore.dataset.audio.Magphase(power=1.0)[source]
Separate a complex-valued spectrogram with shape (…, 2) into its magnitude and phase.
- Parameters
power (float) – Power of the norm, which must be non-negative (default=1.0).
Examples
>>> import numpy as np >>> >>> waveform = np.random.random([2, 4, 2]) >>> numpy_slices_dataset = ds.NumpySlicesDataset(data=waveform, column_names=["audio"]) >>> transforms = [audio.Magphase()] >>> numpy_slices_dataset = numpy_slices_dataset.map(operations=transforms, input_columns=["audio"])
