AB  - We propose a binaural rendering method in the Modified Discrete Cosine Transform (MDCT) domain. It has good compatibility with audio codecs because a number of audio codecs utilize a MDCT filter bank for time-frequency transform. The proposal maps the MDCT coefficients to the real part of the Modulated Complex Lapped Transform (MCLT) coefficients and processes the amplitudes and phases according to the binaural information. The inverse MCLT is applied to the coefficients with a synthesis window function which is derived from the perfect reconstruction condition for the phase shifted signal under the assumption of linear phase property. The proposed method is applicable to the Binaural Cue Coding Type I and offers equivalent subjective quality to the original binaural signal.
