Subject: [PATCH 0/5] mSBC tests
Date: Thu, 27 Sep 2012 16:44:23 +0200 [thread overview]
Message-ID: <1348757068-31048-1-git-send-email-frederic.dalleau@linux.intel.com> (raw)
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.
Regards,
Frederic
