Delay
The Delay effect adds an echo of the audio clip’s sound that plays after a specified amount of time.
Specifies the amount of time before the echo plays. The maximum is 2 seconds.
Specifies a percentage of the delayed signal to be added back into the delay to create multiple decaying echoes.
Controls the amount of echo.
DeNoiser (Windows only)
The DeNoiser effect automatically detects tape noise and removes it. Use this effect to remove noise from analog audio recordings, such as
magnetic tape recordings. Click the triangle beside the Custom Setup button to view the following options:
Stops the noise floor estimation at the current value. Use this control to locate noise that drops in and out of a clip.
Specifies the amount of noise to remove within a range of -20 to 0 dB.
Sets an offset value between the automatically detected noise floor and the value that you specify. This is limited to a range between -10
and +10 dB. Offset allows additional control when the automatic denoising is not sufficient.
Dynamics (Windows only)
The Dynamics effect helps eliminate unwanted background noise, balance the dynamic range, and reduce clipping, or the distortion from over-
amplification. Click the Custom Setup twirl-down triangle to open the following controls:
Specifies the level (in dB) that the incoming signal must exceed. Signals below this level are muted. Use this control to remove
unwanted background noises, such as a background noise behind a voiceover.
Sets the level (in dB) at which compression occurs and the ratio at which compression is applied, up to 8:1. Also controls the attack
time (the time it takes for the compressor to respond), the release time (the time it takes for the gain to return to the original level when the signal
falls below the threshold). The MakeUp control adjusts the output level to account for loss in gain caused by compression. Use the Compressor
controls to increase the volume of soft sounds, decrease the volume of loud sounds, or both.
Reduces all signals below the specified threshold to the specified ratio. The result is similar to the Gate control, but subtler.
Sets the maximum level for signals, between -12 and 0 dB. Signals that exceed the threshold are reduced to the threshold level.
Fill Left, Fill Right
The Fill Left effect duplicates the left channel information of the audio clip and places it in the right channel, discarding the original clip’s right
channel information. The Fill Right effect duplicates the right channel information and places it in the left channel, discarding the existing left
channel information. For example, you might use this effect on footage shot with a monaural microphone plugged into only one channel of a
camcorder, extending the voice of a speaker from one channel to both.
