Downsampling Quality Level
preventing the aliasing of higher frequencies to lower ones. A lower setting results in shorter processing time but also
in the roll-off of certain high frequencies, leading to muffled-sounding audio. Because the filter's cutoff slope is much
steeper at higher quality settings, the chance of ringing at high frequencies is greater. Usually values between 80 and
400 are fully satisfactory for most conversion needs. The default value is 80.

keeping them from generating alias frequencies at the low end of the spectrum. In general, select this option for best
results.
•
Upsampling Quality Level
preventing the aliasing of higher frequencies to lower ones. A lower setting results in shorter processing time but also
rolls off certain high frequencies, leading to muffled-sounding audio. Because the filter's cutoff slope is much steeper
at higher quality settings, the chance of ringing at high frequencies is greater. Values between 100 and 400 address
most conversion needs. The default value is 120.
Use a higher Upsampling Quality Level value whenever you downsample from a high sample rate to a low rate. For
upsampling, a lower value produces quality almost identical to a higher value. The difference lies in the larger phase
shift that exists at higher frequencies, but since the phase shift is completely linear, it's very difficult to notice. Downsam-
pling, at even the lowest values, generally doesn't introduce any undesired noisy artifacts. Instead, the sound might be
slightly muffled because of increased high-end filtering.

keeping them from generating false frequencies at the low end of the spectrum. In general, select this option for best
results.
Dither Amount For Saving 32-Bit Data To 16-Bit Files
The default value of 1 (bit) enables dithering, while a value of 0 disables dithering. For semidithering, choose a value
of 0.5.
With dithering, you can approximate 24-bit performance with 16-bit data, because dynamic range increases by about
10 dB. This allows signals as quiet as –105 dB.
With this option enabled, you can approximate 24-bit performance with 16-bit data, because dithering increases
dynamic range by about 10 dB.
Allow For Partially Processed Data After Canceling Effect

removes the effect on already processed data when you click Cancel.
