Formant Preserve
Prevents formants in the audio clip from being affected. For example, use this control when
increasing the pitch of a high voice to prevent it from sounding cartoon-like.
Reverb effect
The Reverb effect adds ambience and warmth to an audio clip by simulating the sound of the audio playing in a
room. Use the graphical controls in the Custom Setup view, or adjust values in the Individual Parameters view. This
effect is available for 5.1, stereo, or mono clips.
The Reverb effect has the following settings:
Pre Delay
Specifies the time between the signal and the reverberation. This setting correlates to the distance a sound
travels to the reflecting walls and back to the listener in a live setting.
Absorption
Specifies the percentage in which the sound is absorbed.
Size
Specifies the size of the room as a percentage.
Density
Specifies the density of the reverb “tail.” The Size value determines the range in which you can set Density.
Lo Damp
Specifies the amount of dampening for low frequencies (in decibels). Dampening lower frequencies
prevents the reverb from rumbling or sounding muddy.
Hi Damp
Specifies the amount of dampening of high frequencies (in decibels). Low settings make the reverb sound
softer.
Mix
Controls the amount of reverb.
Swap Channels effect
The Swap Channels effect switches the placement of the left and right channel information. Apply to stereo clips only.
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.
