LSL driver: does OpenViBE support non-integer sampling freq.
Posted: Wed Jun 20, 2018 12:15 pm
Hello!
We have an EEG acquisition device which provides a non-integer sampling frequency range, e.g. 121.37 Hz.
Producer provides an LSL server for this device which makes an LSL outlet with 121.37 Hz sampling frequency.
I choose driver: LSL in Acquisition server, set it properly, connect to device and start signal acquisition.
Console of Acquisition server noted "Opened an LSL stream with 8 channels and nominal rate of 121.37 Hz"
In OpenViBE Designer I see the sample rate 121 Hz instead 121.37 Hz, but signal goes well.
The problem is that Acquisition server shows increased in time Device drift and sometimes it becomes freezed.
Does OpenViBE support non-integer sampling freqencies?
All the best,
Stanislav
