22.2ch音響のダウンミックスにおける音質補正手法の検討

抄録

A tone compensation method to downmix a 22.2 ch sound to the audio formats having less channels is proposed. Proposed method compensates the energy spectrum of the downmixed sound according to that of the 22.2 ch sound with downmixing coefficients by suppressing the spectral difference from the 22.2 ch sound.
