auglib is an augmentation library, which provides transforms to modify audio signals and files.
import auglib
transform = auglib.transform.PinkNoise()
augment = auglib.Augment(transform)
augment(signal, sampling_rate)auglib can further augment whole datasets while caching the results. It can be easily extended with external or user defined augmentations.
