@ Sin: I will fix this in the next version. Until then you can use Sleepanalyser by running the following command in XTerm:
python /opt/Sleepanalyser/main.py --language en

@ willem43: I am not going to add sound detection in the near future. This would be a huge task and it would be very difficult to interpret the data.
To record the snoring would be interesting, how ever I do not have the time to implement more huge functions into Sleepanalyser. I spend already far to much time for it
