M4B audiobook

One signature-verified, unencrypted MP4-family audiobook up to 1 GB. This first release advertises fixture-proven AAC-LC audio.

Chapter audio format

M4A stream copy
Copies AAC without re-encoding. Cuts are packet-aligned, not claimed as sample-exact, and measured deltas are reported against the 0.25-second fixture-proven tolerance. MP3 compatibility
Re-encodes with the existing FFmpeg MP3 path at the bitrate you explicitly choose.

I have the right to process this audiobook and understand that DRM-protected files are rejected without decryption attempts.
