2a6039b3f4 Adding code to dump the contents of a mode struct to a C file that can be 
compiled without having to use the initialisation code.

c209c342bf fixed-point: defined HALF32() and used it for the forward mdct. 2008-03-07 17:50:45 +11:00

957a4fae0e fixed-point: real FFT no longer needs float ops when MIXED_PRECISION is enabled. 2008-03-07 17:46:00 +11:00

000973f7e2 fixed-point: compute_band_energies() converted. Had to add some tiny bias to 
make sure never to end up with a pitch vector with >1 norm.

0668b8ea5e fixed-point: converted normalise_bands (had to split implementation) 2008-03-07 15:33:32 +11:00

cefc5ca26d Revert "compute_band_energies() merged with normalised_bands()" 
This reverts commit a1bc18a388.
I think it's easier for now to deal with two functions here, even though they
could be merged.

f8eb420a09 Changed the pulse spreading rotations so that the number of iterations is 
variable instead of the angle. Should now be both less CPU-intensive and
makes fixed-point code simpler.

f93747c44a fixed-point: changed find_spectral_pitch() to use single-precision (16-bit) FFT. 
This involved adding kfft_single.[ch] that redefines kiss_fft a second time
with a different prefix. All this is still a bit of a mess now. The mask
had to be converted to 16-bit input, but we're still using floats to apply it.

b624cdd2ce fixed-point: masking curve computation now converted. ***Fixed a bug in the 
handling of the left side slope of the spreading function (right-side coef
was used)

speexdsp library.

300cb5b86a First attempt at adding a suffix to kiss_fft functions so we can have multiple

632f218b4b Pitch predictor now uses a larger range of offset by not being limited to the 
window size when parts of the window are zero.

0141723d30 compute_mdcts() no longer reads the part of the input that should be zeros 
anyway (check-point for pitch improvements to follow)

3e08a88389 Only the (rising) overlap part of the window is stored now. No need to hold the 
zeros and ones (nor even the second half).
