Experimental¶
A bunch of routines useful when doing measurements and experiments.
- pyroomacoustics.experimental.measure_ir(sweep_length=1.0, sweep_type='exponential', fs=48000, f_lo=0.0, f_hi=None, volume=0.9, pre_delay=0.0, post_delay=0.1, fade_in_out=0.0, dev_in=None, dev_out=None, channels_input_mapping=None, channels_output_mapping=None, ascending=False, deconvolution=True, plot=True)¶
Measures an impulse response by playing a sweep and recording it using the sounddevice package.
- Parameters:
sweep_length (float, optional) – length of the sweep in seconds
sweep_type (SweepType, optional) – type of sweep to use linear or exponential (default)
fs (int, optional) – sampling frequency (default 48 kHz)
f_lo (float, optional) – lowest frequency in the sweep
f_hi (float, optional) – highest frequency in the sweep, can be a negative offset from fs/2
volume (float, optional) – multiply the sweep by this number before playing (default 0.9)
pre_delay (float, optional) – delay in second before playing sweep
post_delay (float, optional) – delay in second before stopping recording after playing the sweep
fade_in_out (float, optional) – length in seconds of the fade in and out of the sweep (default 0.)
dev_in (int, optional) – input device number
dev_out (int, optional) – output device number
channels_input_mapping (array_like, optional) – List of channel numbers (starting with 1) to record. If mapping is given, channels is silently ignored.
channels_output_mapping (array_like, optional) – List of channel numbers (starting with 1) where the columns of data shall be played back on. Must have the same length as number of channels in data (except if data is mono, in which case the signal is played back on all given output channels). Each channel number may only appear once in mapping.
ascending (bool, optional) – wether the sweep is from high to low (default) or low to high frequencies
deconvolution (bool, optional) – if True, apply deconvolution to the recorded signal to remove the sweep (default 0.)
plot (bool, optional) – plot the resulting signal
- Return type:
Returns the impulse response if deconvolution == True and the recorded signal if not
