887ad9ff29 Increased accuracy of the reciprocal approximation and made it use 
MULT16_16_Q15() instead of Q14 (should be faster).

0ac437b82d Testcases should now work even when symbols aren't visible in the dso 2008-03-12 18:04:27 +11:00

31b79d1993 Changed definition of VARDECL to make it more flexible. No actual code change. 2008-03-12 17:17:23 +11:00

493b38d48f Better heuristic for deciding when to use the 32-bit version of the cwrs code. 2008-03-11 15:24:07 +11:00
Jean-Marc Valin
949902fd1b const correctness. celt_mode_create() now makes a copy of the static mode 
(if STATIC_MODES is defined) instead of attempting to modify read-only
storage.

2a6039b3f4 Adding code to dump the contents of a mode struct to a C file that can be

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

3e65097528 Bit of cleaning up. No real code change (well, I hope so!). 2008-03-07 17:38:58 +11:00

a1d95d70ca fixed-point: removed the last float op in celt.c 2008-03-07 17:33:58 +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
Jean-Marc Valin
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.
