mindspore.dataset.audio.transforms.Angle

class mindspore.dataset.audio.transforms.Angle

Calculate the angle of the complex number sequence of shape (…, 2). The first dimension represents the real part while the second represents the imaginary.

Examples

>>> import numpy as np
>>>
>>> waveform = np.array([[1.43, 5.434], [23.54, 89.38]])
>>> numpy_slices_dataset = ds.NumpySlicesDataset(data=waveform, column_names=["audio"])
>>> transforms = [audio.Angle()]
>>> numpy_slices_dataset = numpy_slices_dataset.map(operations=transforms, input_columns=["audio"])
