Cool Edit Pro: Optimizing Multitrack

Performance

Background mixing

the process Cool Edit Pro uses to allow a large

number of tracks to play simultaneously

requires significant processing

power from your computer. With larger sessions, your computer may

become so occupied with mixing that you experience audio dropouts in

multitrack playback. This will usually happen because the background

mixing is not sufficiently complete (watch the Mix Gauge) before playback

is initiated. There are a few things you can do to help remedy this; however,

be aware that you may still have to wait for a time before hitting the Play

button when working with very large sessions.

The settings in Options/Settings/Multitrack play a big part in optimizing

the background mixing processes. In particular, pay attention to the

Playback Buffer Size and the Background Mixing Priority Level. The

key to determining how to adjust these settings is to watch the Mix Gauge.

As a general guideline, if you notice dropouts occurring even though the

Mix Gauge seems reasonably complete (the meter is beyond ¾ of the way

filled), try reducing the Playback Buffer Size, and raising the Background

Mixing Priority Level (higher values reduce the priority level).

Conversely, if you notice dropouts and see that the Mix Gauge is hovering

around the bottom “empty”), try increasing the Playback Buffer Size and

lowering the Background Mixing Priority Level.

The goal in adjusting these settings is to achieve a balance between values

large enough for the program to work properly and low enough to conserve

the computer’s resources. The Background Mix Priority must be high

enough (lower settings produce a higher priority) to keep the mix ahead of

playback, but not be so high as to adversely affect performance (by

consuming too much of your computer’s resources). In short, the lower you

can keep this setting while still keeping the Mix Gauge reasonably filled,

the better. Raising the buffer size consumes more of your computer’s

memory, so setting this too high can negatively affect performance.

When adjusting these settings, do so by small amounts, using decimal

increments/decrements. Also, note that the settings will produce different

results from session to session. As the number of tracks and the number of
