Preparing Audio for Distribution
SONAR Producer offers five kinds of dithering:
• Rectangular—essentially white noise, no noise shaping.
Advantages: least CPU-intensive, lowest signal-to-noise ratio,
preferable to shaped dither when successive dithering can occur
(e.g. bouncing, freezing). Disadvantages: suffers from
intermodulation distortion, higher perceived loudness than Pow-r
dither.
• Triangular—higher level than rectangular, no noise shaping.
Advantages: low CPU-intensive dither, superior to Rectangular as it
does not suffer from modulation noise effects. Preferable to shaped
(Pow-r) dither when successive dithering can occur (e.g. bouncing,
freezing). Disadvantages: higher perceived loudness than Pow-r
dither.
• Pow-r 1—noise-shaped dither. Advantages: less CPU-intensive
than Pow-r types 2 and 3, lower perceived loudness than
Rectangular or Triangular. Disadvantages: less noise shaping than
Pow-r types 2 and 3, not recommended for operations where dither
will be applied successively (e.g. bounce and freeze).
• Pow-r 2—noise-shaped dither. Advantages: lowest perceived
loudness, highest quality settings, recommended for audio export.
Disadvantages: highest CPU-intensive settings, not recommended
for operations where dither will be applied successively (e.g.
bounce and freeze).
• Pow-r 3—same as Pow-r 2 except most CPU-intensive and
transparent of all choices.
To Choose Dithering Options
1. Open the Audio Options dialog (Options-Audio command).
2. On the Advanced tab, under Playback and Recording, choose the kind
of dithering you want in the Dithering field.
3. Click OK.
