Loudness – OP 59

    Changes to the supply of soundtracks for television broadcast

To avoid the excessive loudness contrasts in soundtracks that can be annoying to consumers, a new international standardisation of sound measurement and metering has been introduced in Australia and New Zealand.

As of July 2012, FreeTV Australia moved to bring the metering of soundtracks broadcast in Australia into line with the new international loudness based standards currently enforced in Europe, the US and other parts of the world. 

The new standard, published by FreeTV Australia as Operational Practice OP-59, is based on the perceived loudness of the soundtrack as apposed to a measurement based on the electrical signal of the audio.

Basically the new standards have been put in place to combat viewer complaints of jumps in audio levels between advertisements, station promos, television programs, movies etc.

We final mix all our television broadcast content to the new Operational Practice 59, and we guarantee full compliance to the new standard without any need for further certification from third party services.
