Re: [codec] #15: Efficiently combine pre-encoded audio

A related question is encoder-decoder synchronization time.  Generally audio
codecs are designed so that even if they start decoding with unknown state,
the encoder and decoder synchronize automatically and very quickly.

(Video codecs generally do not have this property BTW).
