On board mic (on camera) – Left Channel – Room. Boom mic – Right Channel – Voice – Ambient sound and as a back up if a channel fails.

Wildtrack – the ambient sound of the room. You need to record 1 minute of wild track.

Wildtrack needs to be recorded to avoid hard cuts in the audio.

Voice – 6PPM (5.5PM and adverts go up to 6PPM)

The sound is compressed between 4ppm and 6ppm between a limiter in commercials. That’s why people sound different in TV programmes and music as they do live.
