House Audio vs Cinematic Audio

July 29, 2009 by admin

There are important distinctions that exist between house audio or public address and cinematic.

House audio must be optimized for understandability in a room that has dynamic auditory characteristics. Sometimes people are coughing, children may be excited, someone may be sitting next to sound absorbing curtains while another may be sitting against a bare wall reflecting sounds, and the list goes on. To optimize understandability a public address system will therefore have a narrow band of frequencies it will put on the loudspeakers usually centered around 3,000Hz, optimum for the human voice. Cinematic audio, or audio for television, serves an audience of just a few people in a relatively small room. Under these conditions the audio is much easier to understand. This leaves room for a much wider band of frequencies enabling a more natural and rich sound.

Capturing audio from a variety of church sound systems we have noticed the practical effect of all this. The sound we typically capture from a house sound board sounds fine in a video until you compare it with audio we captured at the same event with our own microphone systems.

Please view below a sample video illustrating the differences between a typical house audio system and audio for cinema. In the video you will see a pastor delivering a wedding message to a couple during their wedding ceremony. The pastor is double miked wearing both a house microphone and one of our wireless microphones.

The video is in HD high definition so if your bandwidth is too slow click on the HD icon to switch to standard definition. Please bear in mind that this is raw video and not necessarily representative of the quality we release.
