一个简单的音频数据扩充包
augaudio的Python项目详细描述
奥格奥迪
该软件包包含多个简单的音频数据增强，以提高/测试神经网络的鲁棒性。在
原件
高斯噪声
音高偏移
时间延伸
压碎
安装
您可以通过
pip install augaudio
使用
用法示例：
importlibrosaimportaugaudioimportsoundfiley,sr=librosa.load('audio.wav')augmented=augaudio.augment(y,1,4)soundfile.write('augmented.wav',augmented,sr)
直接访问其中一个扩充：
^{pr2}$链扩充在一起：
...augmented=augaudio.GaussianNoise(augaudio.TimeStretch(y,2),4)...
迭代扩充：
...foraugmentationinrange(4):forintensityinrange(1,10):augmented=augaudio.augment(y,augmentation,intensity)soundfile.write(str(augmentation)+'-'+str(intensity)+'.wav',augmented,sr)...
命令行用法：
单个文件：
augaudio /path/to/audio.wav 0 5
完成文件夹：
augaudio /path/to/input 0 5 /path/to/output
扩充
