I just tested my microphone. See https://help.sansar.com/hc/en-us/articles/115002443183-Meeting-Notes-May-12-2017 for instructions.
Now i noticed there's lot's of background noise compared to some other software. It seems sansar does not have a noise reduction filter build in. That would improve voice communication for lot's of people because background noise get supressed from fans etc.
Would be nice to have noise reduction filter on the audio. with checkbox in case it need turned off for testing.
