Object-Based Immersive Encoder Comparison at One Union Recording!

About this event

Object-Based Immersive Encoder Comparison at One Union Recording Studios in San Francisco! Join us for an engaging evening at the forefront of audio innovation. At this event, we bring together professionals, students, and enthusiasts to explore the latest in immersive audio technology. Participate and be part of the conversation that shapes the future of audio engineering. And to all the "Golden Ears" out there, let's see if you can spot the difference between the codecs. Being partly a studio tour as well as a listening exercise, there will be plenty of social time as well. Building a high-fidelity low bit-rate delivery system for streaming immersive music poses significant perceptual and technical challenges. The majority of consumers currently listening to immersive music are hearing the lossy format Dolby Digital Plus with Joint Object Coding (DD+JOC), which has the advantage of backwards compatibility. A newer, non-backwards compatible codec referred to as Dolby Audio Coding Level 4 (AC-4 L4) has become available for commercial deployment and is designed with many more features, including lower bitrate, and higher fidelity than DD+JOC. This event will feature a double-blind listening test that puts reference PCM 7.1.4 up against DD+JOC and AC-4 L4 on a high-quality professional playback system. Attendees will have the opportunity to choose listening material, and solo speaker channels. There will be a short technical discussion from Erik Foreman of SoundForeman. Light hors d'oeuvres and non-alcoholic refreshments will be provided.
