Cycling '74 has released UpMix (Mac/Win; $495), a surround processing and mixing application for converting stereo audio files into a 6-channel mix suitable for film, DVD, HD broadcast, and music surround formats. UpMix includes five additional plug-ins that handle common surround mixing tasks. Rotator moves a 5.1 mix in a circular fashion, which allows the point of view to follow the on-screen action.

ReRoute acts as a universal format router, so you can convert the project from one 6-channel format to another. ReBalance provides a set of level controls for each of the six channels within an interleaved multichannel file or bus. FoldDown lets you check your surround mix in stereo, with standards-based center channel and surround channel gain reduction options.

ReBalance is a simple set of level controls for each of the six surround channels. LFE-6chan is a low-frequency generator/enhancer that can be used with individual tracks and entire mixes.

UpMix is available for Digidesign Pro Tools TDM (Mac OS X or Windows), Steinberg Nuendo and Cubase SX 3 (Mac OS X or Windows), and MOTU Digital Performer (Mac only). For more information, visit Cycling74.com.
