Shape dithering
Webb1 juli 2024 · The dithering signal shapes are sine, square, saw, sinc, and Gaussian with different spectral width characteristics. We show that by varying the dithering signal with increasing spectral width, no additional distortion is introduced in the linear and optimum optical launch power regions, which are dominated by the frequency chirp and chromatic … WebbDithering is the process of adding noise to a signal, in an effort to mask and randomize higher-order harmonics, and in turn, make quantization distortion less perceivable. …

This determines how much noise is introduced to the audio signal. I usually leave this setting at medium. If the dither (noise) is too audible, you can move this setting down to low, or choose a different noise shaping option. Step 4: Select a noise shaping option.
