...ocess of collecting performance data on my platform and I thought I'd test the difference between double and float performance. So, I replaced all occurances of double in vorbis with float (as was suggested should work). I ended up hanging at: #0 0x0002695c in cacm283 () #1 0x00026dd0 in vorbis_lpc_to_lsp () #2 0x0001b3cc in forward () #3 0x0001cac8 in forward () #4 0x0000b844 in vorbis_analysis () #5 0x000030b4 in oe_encode () #6 0x00002230 in main () #7 0x00001a04 in _start () #8 0x000018a8 in start () (gdb) q Is the rewritten LPC/LSP (whatever that is :) that works with floats on the he...

Used command line options: oggenc.exe -b350 track12.wav (btw1: during the encoding we get a 'Domain error in acos' in the vorbis_lpc_to_lsp() function and at the decoding we get 'Overflow range error in exp', but I don't know where is that 'exp' function) (btw2: there is a comment in the lsp.c ... it writes about a possible bug in the floor finder...) (btw3: the beta2 encoder works properly on this fil...
