b0c93c66ea oops, pgain_table now has half the number of elements 2008-03-05 13:12:16 +11:00

afa5eb38b5 fixed-point: quantised the pitch gain table. 2008-03-05 12:22:37 +11:00

92376697c6 fixed-point: converted the pitch gain quantisation, except for the codebook 
itself

a31899f0e2 added suffix to real fft. The celtclient can now be built with an unmodified 
speexdsp library.

300cb5b86a First attempt at adding a suffix to kiss_fft functions so we can have multiple 
copies of the FFT.

05080b4b9b No longer storing the zero parts of the in[] array in the encoder 2008-03-03 14:23:51 +11:00
Jean-Marc Valin
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.
 2008-03-03 14:08:21 +11:00
Jean-Marc Valin
0141723d30 compute_mdcts() no longer reads the part of the input that should be zeros 
anyway (check-point for pitch improvements to follow)
 2008-03-03 13:59:55 +11:00
Jean-Marc Valin
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).
 2008-03-03 13:49:20 +11:00

f28062fe6a Don't bother multiplying when the window's value is one or zero 2008-03-03 13:42:23 +11:00

227ad2f82d cwrs32-test should be 16-bit clean now. 2008-03-03 10:07:19 +11:00

eb5a245ac8 Hadn't realised the bitr* stuff wasn't needed. 2008-03-03 04:11:49 +11:00

37942649cc Saved 4 kB of stack usage in find_spectral_pitch() by doing the FFT in-place 
(sort of)

81b38c2295 Moved mdct state and window to the mode so it can be shared between multiple 
encoders and decoders.

37131e3ab3 Just realised half the twiddles in the real FFT weren't even used. Removing 
them saves another 1kB for fixed-point (2kB for float or full precision)
 2008-02-29 20:03:41 +11:00
