Producer, Peregrine Andrews When we think of the sound of sport on TV or radio, it's generally commentary. But what's around the commentary? Broadcast sport would be nothing without the crowds, the kicks, the thwacks and the grunts. This programme is about those sounds and why they matter.

During the World Cup of 2010, the Vuvuzelas made many people realise that the sound of a sports event, something they took for granted, does matter.

Dennis Baxter's job is to think about the sound of sport, and he is our guide. For nearly 20 years he's worked on the Olympics, defining how the broadcast will sound, always trying to increase drama and excitement. For him, closer is generally better. If he can put a microphone on an athlete, he will.

At the Oxford-Cambridge boat race, the TV coverage is enhanced by microphones on the cox in each boat. Whilst Wimbledon has a special sonic drama all of its own, as we learn from Bill Whiston who mixed the Bafta-nominated sound of the 2008 finals.

When good sound isn't available, it's not uncommon for a prerecorded sound to be added to cover the shot. Is this cheating or merely giving us what we expect?

The experience of "live" events can be highly produced, very different from the experience of being there. Is this enhanced sound so very different from that of a film or a video game? We meet a Hollywood sound effects specialist and a video game sound designer to find out what they do to create a sense of authenticity and excitement. Are they raising our expectations of how "real" sport should sound?

As we approach the 2012 Olympics, this programme will make you think more about what you hear when you watch sport.
