Can a new audio codec make streaming sound as good as lossless Dolby Atmos?

In this video, I share the details of a unique blind listening experiment comparing lossless Dolby Atmos, Dolby Digital Plus (DD+ JOC), and Dolby's new AC-4 immersive audio codec. The goal: determine whether listeners can actually hear the difference between these formats in a high-performance Dolby Atmos theater.

Streaming services such as Netflix, Disney+, Apple TV+, and Prime Video rely on compressed audio formats to deliver Dolby Atmos, while Ultra HD Blu-ray discs typically use lossless Dolby TrueHD. But a new generation of audio codecs promises improved efficiency and potentially higher sound quality at lower bitrates.

Can AC-4 close the gap between streaming and lossless audio? Can trained listeners reliably identify the different formats in a blind test? And what could this mean for the future of home theater and immersive audio?

In this video, I'll break down:
• Lossless Dolby Atmos vs streaming Dolby Atmos
• Dolby TrueHD vs Dolby Digital Plus
• What AC-4 is and how it works
• Results from the blind listening experiment
• Whether listeners could actually hear the differences
• What this could mean for future streaming services

If you're passionate about Dolby Atmos, DTS:X, Auro-3D, home theater, surround sound, and high-performance audio, this is an experiment you won't want to miss.
