audiblelight.augmentation.GSMFullRateCompressor

class audiblelight.augmentation.GSMFullRateCompressor(sample_rate=44100, quality=None)

Bases: EventAugmentation

Applies GSM compression to the audio.

An audio degradation/compression plugin that applies the GSM “Full Rate” compression algorithm to emulate the sound of a 2G cellular phone connection. This plugin internally resamples the input audio to a fixed sample rate of 8kHz (required by the GSM Full Rate codec), although the quality of the resampling algorithm can be specified.

Parameters:

• sample_rate (custom_types.Numeric) – the sample rate for the effect to use.

• quality (int | float | complex | integer | floating | DistributionLike | None) – the quality of the resampling. By default, will be sampled between 0 and 3 (inclusive).

__init__(sample_rate=44100, quality=None)

Parameters:

• sample_rate (int | float | complex | integer | floating)

• quality (int | float | complex | integer | floating | DistributionLike | None)
