Flanger Effect (functional)

Description

Apply a flanger effect to the audio. Similar to SoX implementation.

Usage

functional_flanger(
  waveform,
  sample_rate,
  delay = 0,
  depth = 2,
  regen = 0,
  width = 71,
  speed = 0.5,
  phase = 25,
  modulation = "sinusoidal",
  interpolation = "linear"
)

Arguments

`waveform`	(Tensor): audio waveform of dimension of `⁠(..., channel, time)⁠` . Max 4 channels allowed
`sample_rate`	(int): sampling rate of the waveform, e.g. 44100 (Hz)
`delay`	(float): desired delay in milliseconds(ms). Allowed range of values are 0 to 30
`depth`	(float): desired delay depth in milliseconds(ms). Allowed range of values are 0 to 10
`regen`	(float): desired regen(feeback gain) in dB. Allowed range of values are -95 to 95
`width`	(float): desired width(delay gain) in dB. Allowed range of values are 0 to 100
`speed`	(float): modulation speed in Hz. Allowed range of values are 0.1 to 10
`phase`	(float): percentage phase-shift for multi-channel. Allowed range of values are 0 to 100
`modulation`	(str): Use either "sinusoidal" or "triangular" modulation. (Default: `sinusoidal`)
`interpolation`	(str): Use either "linear" or "quadratic" for delay-line interpolation. (Default: `linear`)
