MediaStoreRecorderSettings.audioFragmentDurationSeconds property
Optional: Target duration, in seconds, of the audio fragments the store records. The video fragments are GOP-driven and unaffected. Because a reader needs both audio and video to play near the live edge, the coarsest fragment size sets the floor on how far behind live it must sit, so a smaller value here lowers achievable latency at the cost of more, smaller objects. Omit (or 0) to keep the 11s default; sub-second values are honoured.
