Working with 5.1 Surround
You can create 5.1-channel mixes to wrap a listener in your remixes or prepare audio for cinema, DVD-Video, DVD-Audio,
or DTS 5.1 Music projects.
Note:
ACID plays, mixes, and renders uncompressed 5.1-channel audio. Authoring software such as Sony DVD
Architect software is required to burn the audio to DVD.
What is 5.1 surround?
5.1 surround is a standard format consisting of three speakers across the front and two speakers in the rear. The “.1” is a
sixth channel called low-frequency effects (LFE) that enhances the bass levels in the mix.
5.1 surround includes five main channels... ...and a sixth channel for low frequency effects.

LFE
The LFE channel is commonly used in motion pictures to enhance low audio frequencies for effects such as explosions or
crashes. Audio in this channel is commonly limited to a range from about 25 Hz to 120 Hz. Unlike the five primary
channels, the LFE channel adds no directional information. Depending on the speaker setup and audio levels, the sound
assigned to the LFE channel may be routed among the five main speakers or to an additional subwoofer.
