What audio bitrate does the AAC file use?

Default AAC bitrate is 192 kbps (transparent for music). You can override to 320 kbps (audiophile) or 96-128 kbps (voice / podcast / smaller file). The choice is exposed in the advanced options before extraction.

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

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

Can I extract just a section of the MP4 audio as AAC?

Not in this single tool — extract the full audio as AAC here, then use /audio-trim/ or /audio-cutter/ to clip the section. The two-step path is faster than a combined operation because we avoid re-decoding the whole file twice.

Kini idi ti fáìlì AAC mì ní àwọn ààyè ìtàjú?

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

Can the AAC extraction be stereo / mono / 5.1?

Channel layout is preserved from MP4 by default — a 5.1 MP4 produces a 5.1 AAC where the codec supports it (AAC, FLAC, OGG, Opus). You can force stereo or mono via the channel-downmix option, which is useful for podcast workflow.

Does the extracted AAC play on iPhone / Android / car stereo?
