Noise gating
Frequently, low-level signals become noise when a file’s bit depth is decreased. For this reason, it is preferable to have complete silence
between sounds in an audio file.
1.
From the Effects menu, choose Noise Gate . The Noise Gate dialog appears
2.
Choose a noise gate preset from the Preset drop-down list and click OK . A noise gate is applied to the audio, negating its low-level
signals.
Compressing
Decreasing the dynamic range of a sound file makes it easier to represent with decreased bit depth.
1.
From the Effects menu, choose Dynamics , and choose Graphic from the submenu. The Graphic Dynamics dialog appears.
2.
Choose a preset with a small amount of compression (2:1 or less) from the Preset drop-down list and click OK .
Normalizing
Normalizing a file prior to decreasing its bit depth ensures that the entire dynamic range is used. In addition, normalization lowers the
signal-to-noise ratio.
1.
From the Process menu, choose Normalize . The Normalize dialog appears.
2.
Select the Peak level radio button.
3.
Set the Normalize to fader to 0 dB (peak) and click OK .
Applying compression and normalization simultaneously
1.
From the Process menu, choose Normalize . The Normalize dialog appears.
