Gain
Adjusts the volume of the selected audio region. The volume is specified as a relative value either in percent or decibels. There are two modes: immediate application and post-normalization:
- Absolute (Immediate) : 100% or 0 dB leaves the volume untouched, 50% or -6 dB halves the volume, and 200% or +6 dB doubles the volume.
- Normalized : The sound is normalized prior to volume modification. Therefore, 100% or 0 dB means maximally normalized to 0 dB digital fullscale, 50% or -6 dB means normalized with a headroom of 6 dB, 200% or +6 dB means the highest amplitude peak is clipped by 6 dB.
