How does it work?

Action Audio works by turning spatial data from real time ball monitoring into 3D sound. The system emphasises ball movements and augments critical moments to allow blind and low vision audiences to follow the game without seeing the ball.

The sound of Action Audio has been informed by four design principles

Social Consideration

Watching sports is a valuable social activity. Action Audio is designed so that everyone can watch together.

Existing Sound Languages

Where possible, we've adopted similar sound cues to those used to blind sports to remain consistent and familiar with the global blind sports community.

Accentuated Tension Points

Sport is all about pushing the limits. Our solution emphasises dramatic moments to signal when a breakthrough is approaching.

Selective Auditory Attention

We filter out sounds around us in order to focus on other things. We designed Action Audio to be ‘filterable’ so as not to unnecessarily distract.

Experience Action Audio for Tennis

In this clip, you can listen to a sample of Action Audio configured for the game of tennis. It features players Ash Barty and Danielle Collins in the second set of the Australian Open 2022 women's singles final.

Imagine you are standing behind Barty and Collins is serving towards you from the far end of the court. Note that the sound design for Action Audio differs between sporting codes.
