How Extemporaneous Audio Description Works

In-Person Events

At a live, in-person event, the Describer, located either in an isolated space or in the audience, observes the proceedings directly and speaks into a microphone:

The microphone signal is fed into a transmitter, which then broadcasts the description into the venue. Patrons use individual, venue-supplied receivers equipped with headsets, earbuds, or portable T-coils to listen to the description.

Virtual Events

At a live, virtual event, the Describer receives an audio-visual feed of the event proceedings and uses that to compose and voice their description. Their microphone signal is sent back to the client and incorporated into their live stream or broadcast for listeners to hear.
