 Graphic display: Shows how the lowest volume levels of your audio material (which
should be mostly or entirely noise) are reduced. Changes to parameters are instantly
reflected here, so keep an eye on it!
Using the Denoiser
Locate a section of the audio where only noise is audible, and set the Threshold value
so that only signals at, or below, this level are filtered out. Then start playback and set
the Reduce value as you listen to the audio, so that as much noise as possible is
reduced, but as little of the desired signal is reduced.
The Denoiser uses FFT (Fast Fourier Transform) analysis to recognize frequency bands of
lower volume and less complex harmonic structure, and then reduces them to the
desired dB level. In principle, this method is completely discrete, as neighboring
frequencies are also affected.
If you use the Denoiser too aggressively, however, the algorithm will produce artifacts,
which are obviously artificial and therefore less desirable than the existing noise in
most cases. If using the Denoiser produces these artifacts, you can use the three
Smoothing knobs to reduce or eliminate them.
Enhance Timing
The Enhance Timing effect non-destructively enhances the timing of audio recordings.
Enhance Timing Parameters
 Intensity slider and field: Determines the amount of timing enhancement. Audio
transients that don’t fall on the grid divisions (determined by the value chosen in the
Grid menu) are corrected.
 Grid menu: Allows you to choose between several grid divisions. As described above,
the grid divisions serve as reference points for the timing correction process.
