[Mp4-tech] [Audio] Audio Conformance test

[Sandip Ray]

Dear All,
  The public domain reference code for AAC (ISO/IEC 14496-5) is floating point code. When I convert that to fixed point code, the output of encoder and decoder doesn't match bitexact with the conformance bitstreams provided by standard body. What is the test for conformance for fixed point audio encoder and decoder ? 
  In case of video we measure PSNR and bitrate of generated bitstream. Is there any similar measurement for audio bitstream ? If you can give any information it will be helpful.
  Thanks and Regards,
  Sandip
