I Hear an Echo When I Record
If you have input monitoring enabled, when you play an instrument that is plugged into your sound
card, you hear the direct signal that goes straight through your sound card, and an instant later you
hear the sound that is processed by SONAR, including any plug-in effects you may be using. Only
the processed sound is recorded.
You can eliminate the echo in either of two ways:
Mute the direct signal so you only hear the sound that is processed by SONAR. If you choose this
method, you may hear too much of a lag between the time you play your instrument and the time
you hear it, depending on the latency of your system (using WDM audio drivers is a great way to
achieve lower latency).
Disable input monitoring so you only hear the raw signal that’s coming through your sound card. If
you choose this method, you won’t hear any plug-in effects you may be using.
To disable input monitoring:
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:
To mute your sound card’s direct sound:
1. Open the software mixer that controls your sound card. If your sound card uses the Windows
mixer, open the mixer by using the Start > Programs > Accessories > Entertainment > Volume
Control command, or by double-clicking the speaker icon on the Windows taskbar.
2. In the Play Control window of the mixer, check the Mute check box in the Line-In column, or in the
column of whatever jack your instrument is plugged into, and close the mixer window.

Dropouts Happen in High Bit-depth or High Sample
Rate Audio
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 a higher I/O buffer size like 256 or 512. If audio problems persist, reset to 128 and try a
different remedy.
Use the Options > Audio command to open the Audio Options dialog, click the Advanced tab,
and in the I/O Buffer Size (KB) field, enter 256 or 512.
