any effect with a “tail” (reverb, delay, etc.) to finish playing when
playback is stopped.
• Always Open All Devices—With this option checked, SONAR opens all
enabled stereo pairs of audio outputs as soon as you press play or turn
on the audio engine. Any pairs that don’t have any tracks feeding them
stream silence, but are still ready for use. So if you then change a
track's output assignment on the fly SONAR doesn’t have to reopen a
device, which can cause gaps in playback.
• Remove DC Offset During Record—With this option enabled, SONAR
filters out any DC Offset disturbances that may be present during
recording. See Removing DC Offset for more information.
Synchronization
SONAR gives you two choices for synchronizing your audio tracks to
SMPTE or MIDI Time Code:
• Trigger and Freewheel—With this option audio playback starts (or
triggers) at the exact timecode, but then the audio plays at its own
internal rate. The audio can gradually drift away from SMPTE time due
to variations in the timecode signal.
• Full Chase Lock—With this option the speed of audio playback is
continuously adjusted to stay with the timecode.
• Timing Offset (msec)—With this option, used for making very fine
adjustments to the audio/MIDI synchronization of your project, you can
offset the audio in your project by a number of milliseconds. A positive
value delays audio by that amount. A negative value delays MIDI by
that amount.
Record Latency Adjustment (samples)
If you loop an audio output back into an audio input, and re-record a track
this way, the audio doesn’t line up. For some sound cards, it is off quite
significantly. This record latency adjustment is a compensation for that
delay.
You can do an approximate measurement of the delay by turning on
samples as the resolution unit in the Time Ruler, and comparing the original
track with the re-recorded track. Then you can enter a value in the Manual
Offset field to compensate.
If you use ASIO mode, enter 0 in the Manual Offset field and leave the
Reported Input Latency checkbox checked (this check box only appears in
ASIO mode). This will line up audio in most cases. If you think you can
tweak it closer, use the Manual Offset field.
