Upload the MP4 file and we demux the audio track, then transcode to AC3. There is no second video pass and no quality loss beyond the AC3 codec itself.

Will the AC3 file be tagged with title / artist / album?

If the MP4 file has chapter or stream metadata, we copy artist / title / album fields into the AC3 container. Otherwise the AC3 file is untagged — use a tag editor (Mp3tag, Picard) post-export if you need richer tags.

Ìgbà wo nínú ìṣàfihàn AC3 láti inú fáìlì MP4 náà?

Audio extraction is much faster than video re-encoding — typically 5-15% of the source duration. A 1-hour MP4 → AC3 finishes in 3-9 minutes on the standard pipeline.

Not in this tool — extract the full audio as AC3 here, then use /audio-trim/ or /audio-cutter/ to clip the section. The two-step path is usually faster than a combined operation.

Silent gaps usually mean the MP4 file had a multi-track audio layout and we picked the wrong stream. Use the advanced "audio stream" option to explicitly pick stream 0, 1, etc., or re-mux all streams to a multi-track AC3 container if AC3 supports it.

Can the AC3 extraction be stereo / mono / 5.1?

MP3 plays everywhere. AAC / M4A plays on Apple and most Android. OGG / Opus needs a recent player on iOS. The advanced options expose a "device" preset that picks the AC3 codec most likely to play on your target.
