This is an updated patch set which does clipping of coefficients
earlier so that processing in-between MDCT and exponent extraction
(e.g. coupling and rematrixing) will use clipped coefficients.
Justin Ruggles (4):
ac3enc: add int32_t array clipping function to DSPUtil, including x86
versions.
ac3enc: clip coefficients after MDCT.
ac3dsp: simplify extract_exponents() now that it does not need to do
clipping.
ac3dsp: add x86-optimized versions of ac3dsp.extract_exponents()
