Two-pole Band Filter (functional) — functional_band

Design two-pole band filter. Similar to SoX implementation.

functional_band_biquad(
  waveform,
  sample_rate,
  central_freq,
  Q = 0.707,
  noise = FALSE
)

Arguments

waveform: (Tensor): audio waveform of dimension of (..., time)
sample_rate: (int): sampling rate of the waveform, e.g. 44100 (Hz)
central_freq: (float): central frequency (in Hz)
Q: (float, optional): https://en.wikipedia.org/wiki/Q_factor (Default: 0.707).
noise: (bool, optional) : If TRUE, uses the alternate mode for un-pitched audio (e.g. percussion). If FALSE, uses mode oriented to pitched audio, i.e. voice, singing, or instrumental music (Default: FALSE).

tensor: Waveform of dimension of (..., time)
