Treble effect
The Treble effects lets you increase or decrease higher frequencies (4000 Hz and above). The Boost control specifies
the amount, measured in decibels, to increase or decrease. This effect is available for 5.1, stereo, or mono clips.
Volume effect
Use the Volume effect in place of the Fixed Volume effect if you want to render Volume before other Standard
effects. The Volume effect creates an envelope for a clip so that you can increase the audio level without clipping.
Clipping occurs when the signal exceeds the dynamic range that’s acceptable for your hardware, often resulting in
distorted audio. Positive values indicate an increase in volume; negative values indicate a decrease in volume. The
Volume effect is available for clips only in 5.1, stereo, or mono tracks.
