Audio for Video: A Complete Guide to Sound in Video Products: From Jitter Buffers and Lip Sync to Atmos, Quality Metrics, and Neural Codecs

This sheet settles ambisonic order, AmbiX format hygiene and generic versus personalized HRTF before you ship spatial audio. Volume 5 covers spatial sound in depth: spatial audio and Atmos, channel-based versus object-based rendering, synchronization and clock domains, and the quality metrics such as ViSQOL and MUSHRA that tell you whether the spatial mix actually works. Written by Nikolay Sapunov, CEO at Fora Soft.
