Abstract (in Japanese) (See Japanese page) 
(in English) In this paper,
we propose a new extension framework of multichannel audio coding
based on temporal quantization of spatial information.
In our previous study, multiple-audio-object signal can be
encoded/decoded via prototypes of directional clustering
for each audio object. This paper, first, pays attention to
the fact that quantized information corresponds to the
spatial image of each sound object,
and is easily modified and operated by the end users.
Next, as a novel application of the spatial image operation,
we propose a new earphone leakage noise reduction method in
which the mostly leaked sound object can be detected
automatically based on the higher-order statistics, and
eliminated. The effectiveness of the proposed CODEC is
verified in the subjective evaluation, and leakage noise
reduction method is assessed in the objective evaluation.
