What is ATRAC3/ATRAC3plus?
ATRAC3 (Adaptive Transform Acoustic Coding3) is an audio
compression technology that satisfies the demand for high sound quality
and high compression rates. ATRAC3plus is a more advanced version of
ATRAC3, and it can compress audio files to about 1/20 of their original
size at 64 kbps.

What is format and bit rate?
Format refers to the recording format, such as WAV or ATRAC3plus.
Bit rate refers to the amount of data processed per second. The larger bit
rates provide, better sound quality. However, the larger bit rates require
more capacity to store the data.
The default setting is OpenMG Audio (ATRAC3plus) for format and 64
kbps for bit rate.
To change the format and bit rate, click "Settings" on the right side of
the SonicStage window.
