Why are 4-channels of audio better than 2-channels?

• Capture more ambient sound at any shoot for an overall more convincing soundscape.
• Place mics on each participant in conferences, panels, reporters, etc.
• Redundancy or backup in case of camera mic noise or drop out.
• Simplify wedding shoots with a mic on the bride, groom, officiator and a mic for ambient sound.
• Video editing environments now support multi-channel audio as standard.
