class data_juicer.ops.mapper.audio_add_gaussian_noise_mapper.AudioAddGaussianNoiseMapper(min_amplitude: float = 0.001, max_amplitude: float = 0.015, p: float = 0.5, save_dir: str = None, *args, **kwargs)

Bases: Mapper

Mapper to add gaussian noise to audio.

__init__(min_amplitude: float = 0.001, max_amplitude: float = 0.015, p: float = 0.5, save_dir: str = None, *args, **kwargs)

Initialization method.

Parameters:

• min_amplitude – float unit: linear amplitude. Default: 0.001. Minimum noise amplification factor.

• max_amplitude – float unit: linear amplitude. Default: 0.015. Maximum noise amplification factor.

• p – float range: [0.0, 1.0]. Default: 0.5. The probability of applying this transform.

save_dir: str. Default: None.

The directory where generated audio files will be stored. If not specified, outputs will be saved in the same directory as their corresponding input files. This path can alternatively be defined by setting the DJ_PRODUCED_DATA_DIR environment variable.

process_single(sample, context=False)

For sample level, sample –> sample

Parameters:

sample – sample to process

Returns:

processed sample
