Decoder conformance for both fixed-point and floating-point implementations shall be tested in accordance with clause 5.1. Conformance shall be verified by either bit-exact behaviour to the reference output or by meeting the objective criteria defined below. Bit-exact behaviour should be preferred for fixed-point implementations where it can be achieved without undue penalty on computational complexity.
5.1 AAC-LC, SBR and Parametric Stereo conformance testing
Conformance testing for AAC-LC, SBR and Parametric Stereo shall be performed according to the relevant clauses in
ISO/IEC 14496-4 [7], [8], [10], [11]. 3GPP conformance shall not be claimed for implementations achieving an accuracy level of K<15 for the "RMS/LSB Measurement" test carried out for AAC-LC.
