pyroomacoustics.experimental.signals module

A few test signals like sweeps and stuff.

pyroomacoustics.experimental.signals.exponential_sweep(T, fs, f_lo=0.0, f_hi=None, fade=None, ascending=False)

Exponential sine sweep

Parameters

• T (float) – length in seconds

• fs – sampling frequency

• f_lo (float) – lowest frequency in fraction of fs (default 0)

• f_hi (float) – lowest frequency in fraction of fs (default 1)

• fade (float, optional) – length of fade in and out in seconds (default 0)

• ascending (bool, optional) –

pyroomacoustics.experimental.signals.linear_sweep(T, fs, f_lo=0.0, f_hi=None, fade=None, ascending=False)

Linear sine sweep

Parameters

• T (float) – length in seconds

• fs – sampling frequency

• f_lo (float) – lowest frequency in fraction of fs (default 0)

• f_hi (float) – lowest frequency in fraction of fs (default 1)

• fade (float, optional) – length of fade in and out in seconds (default 0)

• ascending (bool, optional) –

pyroomacoustics.experimental.signals.window(signal, n_win)

window the signal at beginning and end with window of size n_win/2
