I am porting opus encoder to a low end device with 32K ram, 256K flash and 32MHz arm M3 mcu.
But opus seems consume too much. To make it work , what I can think of
1, Only fixed point supported
2, Only mono voice application supported
3, Set complexity to zero
4, Support only one sample rate, like 16KHz
5, Silk mode only or Celt mode only
My question is , before I start, Shall I choose silk mode or celt mode ?
and beside I mention above, what else can I do to reduce the complexity (rom, ram, MCU),
even compromise the voice quality...
