Calibration

The conversion is set by the CalibSpeaker RePro which defines stimulus intensity as dB SPL, i.e. root-mean-square amplitude of a full-amplitude sine wave.

The calibration table is saved in the files calibD-C.dat where D is the device number of the data acquisition board and C is the analog output channel of that board.

Options

• line: the line on the attenuator
• aodevice: the identifier analog output device
• aochannel: the channel of the analog output device
• maxvoltage: maximum allowed peak voltage to be put out by the attenuator.
