Upload the MKV file and we demux the audio track, then transcode to AAC. There is no video pass and no quality loss beyond what the AAC codec itself imposes; the /extract-audio/ tool runs the same pipeline.
Ìgbà bítárátì àwòrán wo ni fáìlì AAC náà lò?
If AAC is lossless (WAV, FLAC), every sample of the source audio is preserved exactly. If AAC is lossy (MP3, AAC, OGG, Opus), the AAC codec recompresses — at the default 192 kbps this is transparent for nearly all source material.
Does the extracted AAC keep the original sample rate?

Not in this step — extract the full audio as AAC first, then use /audio-trim/ to clip the section. The two-step path is faster than a combined operation and lets you preview the extracted track before trimming.

Silent gaps almost always mean the MKV file had a multi-track audio layout (commentary, alternate languages, surround backchannels) 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 AAC container if AAC supports it.

Channel layout is preserved from MKV by default — a 5.1 MKV produces a 5.1 AAC where the codec supports it (AAC, FLAC, OGG, Opus). Force stereo or mono with the channel-downmix option; useful for podcast workflows or low-bandwidth playback.
Does the extracted AAC play on iPhone, Android, or car stereo?
