Master Audio has the highest bitrate of all at The same as Dolby. Dolby Atmos is a new codec that introduces object-based soundtracks for the first time. It is slowly appearing as a soundtrack option on some Blu-ray releases, and this will increase if the technology becomes popular. Dolby Atmos allows the filmmaker to have additional sound objects which can be added to the channel-based audio.

These objects can place a sound in a 3D environment — and this sound can also be moved — up, down, left, right, forwards and backward. You will need to add a minimum of two height speakers to hear this format — and have an AV receiver that can decode the bitstream from your Blu-ray player.

The good news is that this format is backward-compatible with older Blu-ray players — although you will need a minimum of HDMI 1. The Dolby Atmos soundtrack on your Blu-ray will actually utilize the standard 5. It will just add extra audio effects for the object-based sounds — layered on top of the standard codec. To learn more about Atmos, take a look at my simple guide to Dolby Atmos audio. It requires an AV receiver that supports the decoding of DTS:X, which will then pass the audio to your speaker system — which ideally will have height speakers for the best effect.

However, the main difference from Dolby Atmos is that this format will work on an existing 5. Also, now that we understand the audio soundtracks which are encoded on the disc, it will make it easier when we think about the different types of audio processing that we find on our AV receivers.
