# Real time data streams, recording, and playback

EmotivPRO allows you to view data streams and frequency analyses in real time whenever your headset is connected: both during a recording and when you’re not recording. EmotivPRO also allows you to open and playback saved recordings, including all data streams and frequency analyses.

Note: EPOC Flex now supports Performance Metrics if you map the sensors in the EPOC X configuration.
