incorrect use of MAX16
...finition of MAX16 is type-less,
but I am working on an architecture with hardware support for
min/max of 16bit. Changing the default definition to take
advantage of this hardware changes the result of that
computation.
Please consider the change below for inclusion in the opus
code base.
/* *tf_estimate = 1 + MIN16(1, sqrt(MAX16(0, tf_max-30))/20); */
- *tf_estimate = celt_sqrt(MAX16(0,
SHL32(MULT16_16(QCONST16(0.0069,14),MIN16(163,tf_max)),14)-QCONST32(0.139,28)));
+ *tf_estimate = celt_sqrt(MAX32(0,
SHL32(MULT16_16(QCONST16(0.0069,14),MIN16(163,tf_max)),14)-QCONST32(0.139,28)));
