TSG.dec.2017.
Set up audio recording labs.
The sound recording and EEG labs have been equipped with a setup that enables to present audio
stimuli, to record audio responses, to make stimulus recordings and to monitor the quality of the stimuli
and responses.
The mixer that is used for this is the Behringer Xair18.
This is a professional mixer with 18 analog mono inputs,
10 analog mono outputs, Midi in and out, USB connection
for audio-in-out and control, Ethernet for control and
additional features.
The Behringer is controlled by a program built by the TSG called ‘Beer’. Beer enables researchers to set
and store settings for specific experiments. These specific settings have to be loaded at the start of each
new measurement session ensuring that these stay identical throughout all experiment sessions.
