audio_add_gaussian_noise_mapper¶
Mapper to add Gaussian noise to audio samples.
This operator adds Gaussian noise to audio data with a specified probability. The amplitude of the noise is randomly chosen between min_amplitude and max_amplitude. If save_dir is provided, the modified audio files are saved in that directory; otherwise, they are saved in the same directory as the input files. The p parameter controls the probability of applying this transformation to each sample. If no audio is present in the sample, it is returned unchanged.
向音频样本添加高斯噪声的映射器。
该算子以指定的概率向音频数据添加高斯噪声。噪声的幅度在min_amplitude和max_amplitude之间随机选择。如果提供了save_dir，则修改后的音频文件将保存在该目录中；否则，它们将保存在与输入文件相同的目录中。p参数控制对每个样本应用此转换的概率。如果样本中没有音频，则原样返回。
