High-quality, low-power audio codec!
HE-AAC Version 2 is a technology that achieves both ultra-low bit rates and high sound quality. By combining the existing AAC with SBR (Spectrum Bandwidth Replication) and PS (Parametric Stereo) technologies, it is possible to obtain comparable sound quality with even less information than AAC+SBR. Its capabilities have led to high market expectations, as it has been adopted as a music format for third-generation mobile phones and as a digital radio standard in Europe, and it is anticipated that this technology will rapidly become widespread in the future.
