In this paper, we investigated the influence of stereo coding on the 3D sound localization accuracy. We used the MP3 Mid-Side Stereo encoder and the HE-AAC (aacPlus v2) Parametric Stereo encoder at identical data rates. First, the sound quality of the localized speech signal was checked using MUSHRA subjective tests. The result showed that the quality for HE-AAC is higher than MP3 by 20 points. Next, the sound localization accuracy was estimated, but statistically significant difference was not shown for the encoder nor for the data rate. Moreover, we found that the sound localization accuracy becomes higher than the original non-encoded speech signal between azimuth ranges of + 15 to 60 and -15 to -60 degrees. |
