Apple Soundtrack Pro 3 - Manual (Page 436)

• Joint Stereo checkbox: When deselected, your MP3 files contain one track for the right
stereo channel and one track for the left. In many cases, the two channels contain
related information. When the Joint Stereo checkbox is selected, one channel carries
the information that’s identical on both channels, and the other channel carries the
unique information. At bit rates of 160 Kbps and below, this can improve the sound
quality of your converted audio.
• Smart Encoding Adjustments checkbox: Select this to have Compressor analyze your
encoding settings and music source, and then adjust settings to maximize quality.
• Filter Frequencies Below 10 Hz checkbox: Filtering inaudible frequencies results in smaller,
more efficient files without perceptible loss of quality.
