about

nx_audio_dred_gate.nx -- proves + MEASURES the deep-redundancy keystone (nx_audio_dred): a K-frame redundancy tail recovers a BURST of lost frames with NO retransmit, where 1-frame FEC (our current voice-FEC) leaves a long gap. Also shows the honest depth limit (a burst longer than K leaves B-K gaps -> deeper K needed) + the coarse-frame fidelity + the overhead cost. Cited research: Opus 1.5 DRED recovers up to 1s of loss for 12-32 kb/s at ~1% CPU.
