Audiomentations

A python library for doing audio data augmentation

Setup

pip install audiomentations

Usage example

from audiomentations import Compose, AddGaussianNoise, TimeStretch
import numpy as np

SAMPLE_RATE = 16000

augmenter = Compose([
    AddGaussianNoise(min_amplitude=0.001, max_amplitude=0.015, p=0.5),
    TimeStretch(min_rate=0.8, max_rate=1.25, p=0.5),
])

samples = np.zeros((20,), dtype=np.float32)
samples = augmenter(samples=samples, sample_rate=SAMPLE_RATE)
