Configuring SONAR for Surround Mixing
This section covers setting up SONAR for surround sound.
Using Surround Format Templates
A Surround Format template specifies the number of speakers and the order in
which the speakers are arranged.
There are several different surround formats, including LCRS, 5.1, 6.1, and 7.1,
with 5.1 being most common. The number after the decimal point refers to the
number of Low Frequency Effect (LFE) speakers. However, there are even
different flavors of 5.1. The different flavors specify in which order the speakers
are arranged, and the speaker angles. For example:
The speaker positions, moving clockwise from center, are identified as:
