Denoiser
The Denoiser eliminates or reduces any noise below a threshold volume level.
Denoiser Parameters
 Threshold slider and field: Sets the volume level (the threshold) below which the
DeNoiser reduces the signal.
 Reduce slider and field: Sets the amount of noise reduction applied to sounds below
the threshold. When reducing noise, remember that each 6 dB reduction is
equivalent to halving the volume level (and each 6 dB increase equals a doubling of
the volume level).
For example, if the noise floor of your recording is very high (more than –68 dB),
reducing it to a level of –83 to –78 dB should be sufficient, provided this does not
introduce any audible side effects. This effectively reduces the noise by more than
10 dB, to less than half of the original (noise) volume.
 Noise Type slider and field: Set to a value appropriate to the type of noise you want to
reduce.
 A value of 0 equals white noise (equal frequency distribution);
 Positive values change the noise type to pink noise (harmonic noise; greater bass
response),
 Negative values change the noise type to blue noise (hiss—tape noise).
 Smoothing Frequency knob: Adjusts how smoothing is applied to neighboring
frequencies. If the Denoiser recognizes that only noise is present on a certain
frequency band, the higher you set the Frequency Smoothing parameter, the more it
changes the neighboring frequency bands to avoid glass noise.
 Smoothing Time knob: Sets the time required by the Denoiser to reach (or release)
maximum reduction. This is the simplest form of smoothing.
