Im working on an MP3 decoder with IPP Audio Decoding functions. Through studying ISO 11172-3 I think side information in an MP3 is 17bytes (mono) or 32bytes (stereo) long.
My current test mp3 is mono coded (mode 3 - spec; 1 - intel frame header structure). But the ippsUnpackSideInfo_MP3 function increments the "BitStream" pointer always by 32 bytes.
What am I possibly doing wrong?
