2006-04-10ringing computation now done with 16-bit accuracy.jm
2006-04-09moved some temporary variables from decoder state to scratch spacejm
2006-04-08weighted signal now in 16-bit precision, saving 500 bytes in the encoder statejm
2006-04-08removed unused variables and cleaned up some non-C89nessjm
2006-04-07LPC analysis window now stored as constant in code -> 400 bytes off thejm
2006-04-07another 640 bytes removed from the encoder state (using the input data insteadjm
2006-04-07removed the decoder output buffer -- saving 640 bytes. Synthesis now done withjm

2005-05-26Fixed-point fixes for 16-bit archsjm
2005-05-23Changed storage of lpc coefficients so that it no longer contains a0 (= 1).jm
2005-05-02Added some control on the aggressiveness of the pitch predictor in the form ofjm
2005-04-29Think I fixed the PLC slowdown due to denorm/underflow. Also don't re-jm
2005-04-25Autodetection of C99 variable arrays and alloca. The pseudo-stack is only usedjm

2005-03-15Merged a modified version of Jamey Hicks' C55 patch, fixed ajm
2005-03-03Now possible to put temporary arrays directly on the (real) stackjm
