Audio Driver Bit Depth
Determines the number of bits per sample used for communicating with the
audio hardware for playback. Your audio hardware must be capable of
supporting the setting you supply here. In SONAR™, choose between 16,
18, 20, 22 and 24. In most cases, even if your hardware is "advertised" as
being 18 or 20 bit, you will want to set this value to 24 for optimum
performance.
Note: Using an audio driver bit depth that is greater than 16 means you also
need to choose a preferred setting in the Stream >16 Bit Data As field on
the Driver Profiles tab of this dialog box.
Double-precision Engine
Enabling this checkbox chooses 64-bit (double-precision) mixing in SONAR
throughout the entire signal path. This includes dithering and plug-ins.
SONAR will send and receive 64-bit data to and from all plug-ins that
accept 64-bit data. If a plug-in requires 32-bit data, SONAR will send and
receive 32-bit data.
Stereo Panning Law
Use this menu to choose a panning law for the current project and new
projects. The current project’s panning law is also displayed in the File Stats
window, which appears when you open the File Info dialog (File-Info
command), and click the File Stats button.
Determines the mathematical formula used to control panning. The choices
are:
• (Default) 0 dB center, sin/cos taper, constant power—this choice
causes a 3 dB boost in a signal that’s panned hard left or right, and no
dip in output level in either channel when the signal is center panned.
• -3dB center, sin/cos taper, constant power——this choice causes no
boost in a signal that’s panned hard left or right, and 3dB dip in output
level in either channel when the signal is center panned.
• 0dB center, square-root taper, constant power—this choice causes a 3
dB boost in a signal that’s panned hard left or right, and no dip in output
level in either channel when the signal is center panned.
• -3dB center, square root taper, constant power——this choice causes
no boost in a signal that’s panned hard left or right, and 3dB dip in
output level in either channel when the signal is center panned.
• -6dB center, linear taper——this choice causes no boost in a signal
that’s panned hard left or right, and 6dB dip in output level in either
channel when the signal is center panned.
