This selection directly affects CPU usage. In addition, holding the pointer above a ruler and using your mouse wheel will zoom the display in and out.Īlgorithm - affects the quality and computational complexity of the noise reduction. Scrolling and Zooming - by grabbing and moving the horizontal and vertical rulers, you can adjust what part of the graph is shown. White curve (Residual Noise) - desired noise floor after denoising, can be controlled by Reduction and Residual whitening controls (Advanced mode only) Yellow curve (Output) - spectrum of denoised (output) audio signalīlue curve (Noise Profile) - equals learned noise profile + threshold elevation control Purple curve (Input) - spectrum of input audio signal The Noise Spectrum display shows useful information during both playback and when the noise reduction process is being applied. If either of these parameters changes, the noise profile should be re-collected with the updated parameters for accurate noise reduction results. Note: The noise profile will be valid only for the currently selected FFT size, current sampling rate and number of channels. If you do not have a section of the recording that contains only noise, selecting a quiet region of the recording that contains mostly noise can also work.
This will create a noise profile that Denoiser will use to process the recording.
To train Denoiser, select a section of the recording that contains only noise and click Train. Stationary noise can include tape hiss, microphone hum, power mains buzz, camera noise and other types of noise that do not change in level or spectral shape throughout the recording.ĭenoiser can learn the type of noise you want to remove from the recording to give you the best results.

For more information on how to use Denoiser see the Users Guide.ĭenoiser is designed to reduce stationary noise, including broadband noise, in audio signals. This page contains reference information about this module. In this course, join Garrick Chow as he covers the best and latest features of iZotope RX 6, and demonstrates techniques for fixing audio problems in a variety of situations. iZotope RX 6 is a powerful, industry-leading tool for fixing audio issues.
First I demonstrate how to use the Learn function to grab a.
