+AC-3 (Dolby Digital) is a widely supported lossy multichannel audio codec used in DVD, broadcast, set-top boxes, and legacy home-cinema systems. This article explains how to encode AC-3 audio using FFmpeg with safe, standards-compliant settings.

+AC-3 audio supports mono, stereo, and multichannel output at sample rates of 32 kHz, 44.1 kHz, and 48 kHz. For stereo sources, the usable quality range begins at 160 kbps, with 192–224 kbps being typical for transparent or near‑transparent output.
