About the E-AC3 format
E-AC3 (Dolby Digital Plus) is the streaming-generation successor of the classic AC3: better audio at roughly half the bitrate, support for up to 15.1 channels, and the mandatory audio codec of UHD Blu-ray and most streaming-TV platforms. Netflix, Amazon and broadcast IPTV all ship it.
For authoring streaming deliverables, E-AC3 at 192-384 kbps is the safe standard. For editing or everyday playback, convert it to WAV/MP3 first — few audio editors accept it natively.
