Why does my M4A file have silent gaps?
+
Silent gaps almost always mean that the MOV file had a multi-track audio layout (commentary, alternative languages, surround backchannels) and we selected the wrong stream. Use the advanced "audio stream" option to explicitly choose stream 0, 1, etc., or re-mux all streams to a multi-track M4A container if M4A supports it.

MP3 plays universally. AAC / M4A plays on Apple and almost all Android. OGG / Opus needs a recent player on iOS but plays fine in Chrome / Firefox / VLC. The advanced device preset picks the M4A codec most likely to play on your target system.
