Denoiser eliminates or reduces any noise below a threshold volume level. It does this by using Fast Fourier Transform FFT analysis to identify frequency bands of lower volume and less complex harmonic structure, which it then reduces to the defined decibel level.
If you use Denoiser too aggressively, logic pro x denoiser missing free may encounter artifacts that are less pleasant than the existing noise. Use the three Smoothing knobs to reduce or eliminate these artifacts. See Legacy Denoiser smoothing controls. Threshold slider and field: Set the threshold level to a point below which the noise signals are reduced.
Locate a section of the audio where only noise is audible, then set the Threshold slider to a dB value that filters only signals at or below this level. Reduce slider and field: Set the amount of noise reduction applied to signals that fall below the threshold. Aim for a Reduce slider value with which noise reduction is optimal but little of the music or vocal signal is reduced. Each 6 dB reduction halves the volume level, and each 6 dB logic pro x denoiser missing free doubles it.
This reduces the noise by more than 10 dB, to less than half its original volume. Graphic display: Shows how the lowest volume level signals in your audio material, which are mostly or entirely noise, are reduced.
