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 compares lip-sync and avatar jobs, five open-source models, three commercial platforms and the consent rules for talking-head video. Volume 5 covers the audio side that makes a talking head believable: lip sync and synchronization, timestamps and clock domains, neural codecs and the quality metrics that tell you whether speech and picture line up. Written by Nikolay Sapunov, CEO at Fora Soft.
