Speech Volume Leveler effect
The Amplitude and Compression > Speech Volume Leveler is a compression effect that optimizes dialogue, evening
out levels and removing background noise.
For the best results, do the following:
Select audio with the lowest level. Set Target Volume Level and Leveling Amount to the left. Start playback, and
1
gradually increase the Leveling Amount until speech becomes nicely audible without increasing background noise.
2 Select audio with the highest level, and start playback. Adjust the Target Volume Level until the volume matches
the loudness of the quiet passage you adjusted previously.
3 If necessary, readjust the Leveling Amount to avoid an over-compressed sound.
Here are additional details about each option:
Sets the desired output level relative to zero dBFS. (See
Target Volume Level
page 6.)
At low settings, amplifies speech slightly without boosting the noise floor. At high settings, amplifies
Leveling Amount
the entire signal more as the signal drops closer to the noise floor.
Interprets shorter, low-volume passages as speech that should be amplified. For most audio

content, deselect this option to produce smoother sound.
Click the triangle to access the following options:
Advanced settings
•
Maintains a strong level if the processed signal falls below a threshold relative to zero dBFS.
Compressor
•
Eliminates background noise by dramatically reducing output level when the signal drops by an offset

you specify.

Tube-modeled Compressor effect
The Amplitude And Compression > Tube-modeled Compressor effect simulates the warmth of vintage hardware
compressors. Use this effect to add subtle distortion that pleasantly colors audio.
Sets the input level at which compression begins. Possible values range from -60 to 0 dB. The best
Threshold slider
setting depends on audio content and musical style. To compress only extreme peaks and retain more dynamic range,
try thresholds around 5 dB below the peak input level; to highly compress audio and greatly reduce dynamic range, try
settings around 15 dB below the peak input level.
To the left of the slider, these meters measure input amplitude. Double-click the meters to reset

peak and clip indicators.
To the right of the slider, these meters measure amplitude reduction with red bars that extend
Gain Reduction meters
from top (minimal reduction) to bottom (maximum reduction).
Boosts or cuts amplitude after compression. Possible values range from -18 to +18 dB, where 0 is unity gain.
