+-- added macro PREPROCESS_MDF_FLOAT to allow using of floating point
+-- in mdf and preprocess while keeping fixed point in encoder/decoder
+-- This is due to the fact that preprocess/mdf run faster on floating

+(4) fftwrap.c

+
+-- created a new USE_COMPACT_KISS_FFT for fftwrap.c and shifted defination
+-- to config file so that user configure the usage of fft on config.h
+-- TOEXPLORE:is it possible to share table between mdf/preprocess?
+-- Introducing this macro made the following changes in C code
+-- New macro to facilitate integration
+(grouping real/complex for dc and nyquist frequency seems to require a large
+amount of memory for mdf, therefore did not made the changes for that)
+(1) modify preprocess.c on init and destroy
+(2) modify mdf.c on init and destroy
+(3) shifted power_spectrum to fftwrap.c to share optimised code between
+ preprocess.c and mdf.c
+
+################# NOTES ##############################
+(1) fixed point encoding/decoding is tested on narrowband
+ - some of the QX fractions are packed together to
+ (frac1 * a + frac2 * a) >> X (should be more accurate in rounding)
+ instead of
+ ((frac1 * a) >> X) + ((frac2 * a) >> X)
+ will cause some different between optimized and unoptimized code.
+ tried decoding/encoding optimized code on some audio files retains
+ the clearity of the word
+
+ - wideband/ultrawideband is not heavily tested yet
+
+(2) optimized fixed point code requires memory alignment
+ - used config to debug on functions where memory is not align
+
+(3) floating point optimization for preprocess/mdf is tested
+ fixed point is not tested yet (except fft/filterbank)
+ Note (1) also applies to sround in fft for fixed point
+ some optimization is provided for fixed point as it requires lesser
+ memory compared to floating point.
+
+(4) unroll configurations provided to reduce code size if required
+
+(5) use profile options only if compiler profiling fails to work
+
+(6) can't include the makefile as it is close proprietary
+
+################# TODO:For Trimedia ##############################
+(1) Possible add TSSA wrapper for codec but don't think this can be open source.
+(2) Optimizations for fixed point in mdf/preprocess
