audiblelight.augmentation.Phaser#

class audiblelight.augmentation.Phaser(sample_rate=44100, rate_hz=None, depth=None, centre_frequency_hz=None, feedback=None, mix=None)#

Bases: EventAugmentation

Applies a phaser to the audio.

A 6 stage phaser that modulates first order all-pass filters to create sweeping notches in the magnitude frequency response. This audio effect can be controlled with standard phaser parameters: the speed and depth of the LFO controlling the frequency response, a mix control, a feedback control, and the centre frequency of the modulation.

Parameters:

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

  • rate_hz (int | float | complex | integer | floating | DistributionLike | None) – the speed of the LFO controlling the frequency response. By default, sampled between 0 and 10 Hz

  • depth (int | float | complex | integer | floating | DistributionLike | None) – the depth of the LFO controlling the frequency response. By default, sampled between 0 and 1.0.

  • centre_frequency_hz (int | float | complex | integer | floating | DistributionLike | None) – the centre frequency of the modulation. By default, sampled between 1 and 20 ms.

  • feedback (int | float | complex | integer | floating | DistributionLike | None) – the feedback of the effect. By default, sampled between 0.0 and 0.9.

  • mix (int | float | complex | integer | floating | DistributionLike | None) – the dry/wet mix of the effect. By default, sampled between 0.1 and 0.5.
