adding low-level random noise or “dither” to the audio signal. Different mathematical calculations
are used to generate dither, each method has advantages and disadvantages depending on the
particular operation. SONAR features the
Pow-r
dithering process, short for

eduction, which can produce lower-bit files that sound indistinguishable
from higher-bit source files. When this option is turned on, SONAR uses dithering when you
export a higher-bit file at a lower resolution, or lower the bit depth of a project’s audio files by
using the
Utilities > Change Audio Format
command, or when you “render” audio (bounce,
freeze, or apply effects).
This option is turned on whenever the
Dithering
field has a value other than
None
. You can
choose bit depths for recording, importing, and rendering (bouncing, freezing, and applying
effects) in
Edit > Preferences > File - Audio Data
, and for exporting in the
Export Audio
dialog
box (
File > Export > Audio
command). SONAR 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.
•
Share Drivers With Other Programs.
This option allows other software to access device
drivers. When this option is checked, other software can access device drivers when SONAR is
not the focus of Windows.
•
Use Multiprocessing Engine.
This option is grayed out unless you have a multiprocessor
computer. If you have a multiprocessor computer, check this option if you want SONAR to use
both processors at all times. If you do not check this option, SONAR still uses the second
processor for some tasks.
•
Use MMCSS.
This option gives real-time applications such as SONAR higher priority for
resource scheduling (thread scheduling) under Windows 7 (leave it checked).
•
Always Stream Audio Through FX.
If any tracks or buses contain active plug-in effects, the
audio engine will be activated and stream silence through the effects, even if the tracks have no
audio data or Input Echo enabled. You will typically only disable this option if you want to
conserve a bit of CPU processing if you play a project that contains lots of empty audio tracks with
effects. There are several benefits to having this option enabled:
