1. An apparatus, comprising:
a microphone to receive audio signals;
a radar to collect data on users in a location;
a memory to store known body positions associated with having a side-conversation; and
a processor in communication with the microphone, the radar, and the memory, wherein the processor is to:
determine that a user is having a side-conversation based on the data collected by the radar compared to the known body positions associated with having a side-conversation; and
filter noise associated with the side-conversation received by the microphone from a direction associated with the user.
