Dropouts happen at high bit-depths or high sample rates
• On the track where you want to disable input monitoring, click the track’s Input Echo button
so that it is in the Off position:

Dropouts happen at high bit-depths or high sample
rates
If you are hearing consistent dropouts/clicks in your audio and if your project contains high bit depth
(32/64 bit) or high sample rate audio (88.2K or higher), it may be indicative of a too small I/O buffer
size. If so, try doubling the I/O buffer size to 512. If audio problems persist, reset to 256 and try a
different remedy.
Go to Edit > Preferences > Audio - Sync and Caching, and set Playback I/O Buffer Size (KB)
and Record I/O Buffer Size (KB) to 256, 512 or 1024.

Patching an effect into SONAR causes a dropout
You may have simply reached the maximum number of tracks and effects your CPU can handle. If
this is the case, there are several things you can try:
• Freeze tracks and synths that you presently don’t need to edit. For details, see “Freeze tracks and
synths” on page 909.
•Use the Bounce to clips command to mix down clips that contain a lot of edits (clip effects,
automation, AudioSnap, etc). Doing so will decrease the amount of data your system has to
process simultaneously. For details, see “Bouncing to clips” on page 835.
• If you are using V-Vocal, a lot of processing power may be required from your system. For best
performance, it is recommended that you use a clip as small as possible to apply the V-Vocal
effect, then use the Bounce to Clips command to mix down any final V-Vocal Region FX clips
that don’t require any more editing.
• Open the C:\Cakewalk Projects\Picture Cache folder and delete its contents (do not
delete the folder itself). Doing so will free up disk space so SONAR may perform more efficiently.
However, if SONAR’s CPU meter does not appear to be maxed out, or other plug-ins seem to work,
you may need to address the problem by editing a line in the Aud.ini file. You can edit the
Aud.ini file from within SONAR.
1. Go to Edit > Preferences > Audio - Configuration File.
2. In the Properties list, scroll down to the property named ExtraPluginBufs.
