I hope you are able to help us with this. We currently have no
implementation. Victor Shcherbatyuk has been tinkering with fixed point
but was getting noisy audio last I heard and has not contributed
anything yet.
If you look in sbc/sbc.h, you'll see some fixed point functions like
fxmult and conversion functions. Currently, the precision is set to 20
bits. This is probably not enough, but after you change it to get more
precision, the fixed point tables in sbc_tables_f.h need to be
regenerated; build gen_fixed.c by hand and run
./gen_fixed > sbc_tables_f.h
to do that.
Can I help in any other way?
thanks!
Brad
