Based on different physical and psychoacoustic considerations, there are various Ambisonics decoding methods. The perceived performances of reproduction depend on the order and decoding method of Ambisonics. The present paper analyzes and compares the timbre coloration in horizontal Ambisonics with basic, maximize energy location vector (max-rE) and in-phase decoding methods, respectively. The binaural loudness level spectra (BLLS) for Ambisonics reproduction are calculated by using Moore’s revised binaural loudness model and then used as the criterion to evaluate the timbre coloration. Results indicate that, overall, the basic decoding method is superior to the other two methods in terms of the deviation of BLLS. This conclusion is valid for Ambisonics with various orders as well as in the central and off-central listening position.
