What are the choices for low latency codecs, and what is the fundamental information/perceptual trade-off?
I see that large block sizes are needed to do operations on narrow frequency bands, suitable for some masking stuff, but exploiting temporal correlation could be done against a historical reference (not introducing significant delay)? -k |
