pyFDN.plot_impulse_response#

pyFDN.plot_impulse_response(*irs, fs=None, labels=None, mulaw=True, mu=255.0, title='Impulse response', max_points=10000)[source]#

Plot one or more impulse responses over time, mu-law compressed by default.

Mu-law companding (pyFDN.mulaw_encode()) keeps the quiet late part of a reverberant decay visible alongside the early reflections. Dense traces are downsampled with LTTB (downsampled_scatter()) before plotting.

Parameters:

  • *irs (ArrayLike) – One or more 1-D impulse responses, plotted as overlaid lines.

  • fs (float | None) – Sample rate in Hz. If given, the time axis is in seconds; otherwise in samples.

  • labels (Sequence[str] | None) – One legend label per impulse response.

  • mulaw (bool) – Apply mu-law companding to the amplitudes. Default True.

  • mu (float) – Mu-law compression parameter. Default 255 (G.711).

  • title (str | None) – Figure title.

  • max_points (int) – Maximum number of points per trace after downsampling. Default 10000.
