volume
Specifies the volume setting of your channel represented as a 16-bit, fixed-point number. The high-order 8 bits contain the integer part of the value; the low-order 8 bits contain the fractional part. Volume values range from -1.0 to 1.0. Negative values play no sound but preserve the absolute value of the volume setting.

DESCRIPTION
Use this volume setting during playback--this setting should not affect the record level or the volume of the track in the recorded QuickTime movie.
