Properties

Property Type Description

Property	Type	Description
frameBufferSize?	number	(Optional) Number of audio frame buffers MTL keeps in flight for this sender — a count, not a byte size. At 4 ms ptime each slot is ~768 bytes (PCM16 stereo), so going larger is cheap and absorbs more PS-side pacing jitter. Defaults to 8 (32 ms cushion at 4 ms ptime); MTL’s minimum of 2 is too small for realtime PS sources, drains the ring on any pacing dip and causes MTL to skip an epoch. An `AM824` `nonPcm` sender keeps at least 100 ms of slots, whatever this says: each of its bursts is a whole compressed frame (up to ~42 ms) written at once.
