Dithering. Prepare studio-quality audio for CD and other formats with Ozone’s essential dithering tools. Ozone allows you to effectively convert and dither to 24, . I am using iZotope’s MBit + Dither in the Master section of Wavelab 9 to dither from 24 bit to 16 bit for CD replication. My question is – Using the. Most popular limiters such as Fab Filter’s Pro-L, Wave’s L2 and iZotope’s Ozone have a dither option. You typically place a limiter at the end of.

Dither is a necessary process when ddither from a higher bit resolution to a lower bit resolution. Dithering is used to tame the quantization distortion that happens when converting between bit depths due to requantization.
Dither also preserves more of the dynamic range of a signal when converting to a lower bit depth.
The result is a more pleasing sound and smoother fades. It is possible to provide more effective and transparent dithering by shaping the dithered noise spectrum so less noise is in the audible range and more noise is in the inaudible range.
You can control the aggressiveness of this shaping, ranging from None no shaping, plain dither through Ultra roughly 14 dB of audible noise suppression. More noise shaping can cause slightly higher duther in your signal, even at high bit depths. The dithering amount can be varied from None noise shaping only to High.
In general, the Normal dither amount is a good choice. No dithering or Low dither amount can leave some non-linear quantization distortion or dither noise modulation, while higher settings completely eliminate the non-linear distortion at the expense of a slightly increased noise floor.
iZotope MBit + Dither and Noise Shaping choices –
Mutes dither output i. Dither noise is random in nature and has a very low amplitude. If such high peaks are undesirable, you can enable this option to effectively suppress the spurious peaks in the noise-shaped dither. If, for some reason, izootpe dithering noise is undesirable, simple truncation remains the only choice.
Truncation results in harmonic quantization distortion that adds overtones to the signal and distorts the timbre. In this case you can enable Suppress Harmonics option to slightly alter the truncation rules, moving the harmonic quantization distortion away from overtones of audible frequencies. This option doesn’t create any random dithering noise floor.
Instead it works more like truncation, but with better tonal quality izltope the resulting signal. This option is applicable only in the modes without dithering noise and without aggressive noise shaping. Dither Dither is a necessary process when converting from a higher bit resolution to a lower bit resolution. New bit depth This sets the target resolution bit depth of the audio file.
Noise shaping Chooses the aggressiveness of dither noise shaping. Dither Amount The dithering amount can be varied from None noise shaping only to High. Auto-blanking Mutes dither output i. Limit noise peaks Dither noise is random in nature and has a very low amplitude.
Suppress izoyope If, for some reason, any dithering noise is undesirable, simple truncation remains the only choice.
