This is going to be a problem. Assuming you mean 8 mega*byte* (and not 8 megabit), that's still only 2 kilobit/second. Opus pretty much requires 8 kb/s, so 4 times what you have. The only codec I know that can do 2 kb/s with reasonable quality is codec2, and the implementation is floating po...

Hi, First of all, I'm quite new to opus. I'm trying to use fixed point opus on an ATMEL AT32UC3B0512. I added the opus source into mine sw tree, I trim off code I don't use (eg. arm, x86 folders) It compiles, but the generated image is too big to fit in the flash. Have I any way to reduce the source footprint? (Eg. throw away unecessary files, if there are any..) Thanks, Daniele.
