Denoiser Main Parameters
The Denoiser offers the following main parameters:
Graphic display
Reduce slider and field
Threshold slider and field
Noise Type slider and field
• Threshold slider and field: Sets the threshold level. Signals that fall below this level are
reduced by the Denoiser.
• Reduce slider and field: Sets the amount of noise reduction applied to signals that fall
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).
Note: 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 doesn’t 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: Determines the type of noise that 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 (hissy tape noise).
• 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.
