NB encoder with multiple channels
I am trying to implement a relatively high number of encoders (24/32) on a
single DSP and would like to minimize the memory requirements. Has anyone
optimized the persistent EncState memory allocation for multiple channels.
The default C64x fixed point implementation allocates 5280 bytes of
persistent memory per encoder.
I'm willing to restrict my settings to complexity 1, quality 3.
