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.
Denoiser Smoothing Parameters
The Denoiser offers the following smoothing parameters:
Time knob and field
Frequency knob and field
Transition knob and field
• Frequency knob and field: 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 parameter, the more it changes the neighboring frequency
bands to avoid glass noise.
• Time knob and field: Sets the time required by the Denoiser to reach (or release)
maximum reduction. This is the simplest form of smoothing.
• Transition knob and field: Adjusts how smoothing is applied to neighboring volume
levels. If the Denoiser recognizes that only noise is present in a certain volume range,
the higher you set the Transition parameter, the more similar-level values are changed,
in order to avoid glass noise.
Enhance Timing
Enhance Timing is designed to tighten up loose playing of recorded audio in a production.
It can be used on a variety of materials and works in real time.
