__init__()

lasp.lasp_reverb.ReverbTime.__init__	(		self,
			fs,
			level,
			channel = 0
	)

Initialize Reverberation time computer.

Args: fs: Sampling frequency [Hz] level: (Optionally weighted) level values as a function of time, in dB. channel: Channel index to compute from

compute()

lasp.lasp_reverb.ReverbTime.compute	(		self,
			istart,
			istop
	)

Compute the reverberation time using a least-squares solver.

Args: istart: Start time index reverberation interval istop: Stop time index of reverberation interval

Returns: dictionary with result values, contains:

• istart: start index of reberberation interval
• istop: stop index of reverb. interval
• T60: Reverberation time
• const: Constant value
• derivative: rate of change of the level in dB/s.
