I recently hooked up AMRWB to an application of ours. It works well between two versions of the AMRWB using Intel IPP library, but sounds horrible when decoding a bitstream from another AMRWB library. Is it completely bitstream compatible? It seems the output sizes from the IPP AMRWB codec are different than the other library.
Is network byte order a problem?
Thanks

Hi
Which version of IPP do you use the AMRWB from?In IPP 5.0 compare to IPP 4.1 the bug was fixed in AMRWB codec which caused abitstream incompatibility.

We're using IPP 5.0. It's strange because even the data sizes coming out of the encoder don't match what the other vendor's codec does. Both claim to support the AMRWB spec, but audio is completely incomprehensible between the two. Is the AMRWB in IPP 5.0 known to interoperate with other codecs? Also, I noticed someone pointed out a bug a few months ago in the sample codec. It doesn't appear that this has been corrected. Do you know what the correct version would look like?
Thanks
