Hi folks, I wanted to know more about mSBC and I look into the spec and saw it was just a set of settings for SBC. So I tried to exercise them using sbcenc and sbcdec and found it wasn't possible, I ended modifying SBC library and now it should be possible to use mSBC settings. Using 15 block doesn't work using SIMD processing because of data reordering so I recalled some legacy C code from an older release (sbc_analyse_eight) and put in a separate primitives file. Work done from the spec, not tested with any reference encoder. How to use: sample.au should be an .au audio file 16000hz 16bits 1 channel pcm. $ src/sbcenc -m -b26 -B16 -s8 sample.au > sample.au.msbc $ src/sbcinfo sample.au.msbc $ src/sbcdec -m -f sample.au.msbc.au sample.au.msbc $ mplayer sample.au.msbc.au Note sure there is any application yet but I thought I should share.
