iZotope MBIT+ Dither |
|
From the Process menu, choose Bit Depth, and then choose iZotope MBIT+ Dither from the submenu to convert sound files to different bit depths and apply dithering.
Because the signal-to-noise ratio decreases when you decrease the bit depth of a file, you should maximize the volume of the sound file using the Volume or Normalize functions before performing the conversion.

Noise shaping |
Choose a setting from the drop-down list to control the amount of noise shaping that will be applied. When Type 1 or Type 2 is selected in the Dither mode drop-down list, the following settings are available:
When MBIT+ is selected in the Dither mode drop-down list, you can choose a setting from the Noise shaping drop-down list to control the amount of noise shaping applied. Increased settings will provide more audible noise suppression at the expense of a higher noise floor. | ||||||||||

Dither bits/amount |
When Type 1 or Type 2 is selected in the Dither mode drop-down list, you can choose a setting from the Dither bits drop-down list to choose whether you want to use 1 or 2 dither bits. 1 works well for most applications. When MBIT+ is selected in the Dither mode drop-down list, you can choose a setting from the Dither amount dro | ||||||||||

Silence harmonics |
Select this check box if dithering distorts the timbre of your audio. When the check box is selected, harmonic quantization distortion is moved away from the overtones of audible frequencies. |
Increasing a file’s bit depth cannot improve the quality of the existing audio, but does allow higher resolution for processing.
