Get UM225 UM226 Black Friday pricing on two Waves upmixers that turn stereo into 5.0 or 5.1 surround, with 79% off taking the pair to $29.99 until Nov 26, 2026.

UM225 handles 5.0. UM226 handles 5.1 and adds an LFE channel.

What do UM225 and UM226 do?

Waves says surround and immersive formats keep growing in importance, so upmixing legacy stereo material has become a standard job. These plugins cover that.

They convert stereo audio to surround, whether that's a whole film or TV show or just the music.

Eight modes spread different kinds of program material across the L/R and L/R surround speakers. Each mode is built for a different type of source.

What controls shape the surround field?

Several controls let you tune the result once a mode is chosen:

• Ambience controls make the surround stage smaller or larger
• Punch controls divide transients between L/R and the center channel
• Output trims for L/R, Center and L/R surround
• A display that shows how energy spreads across the surround field
• An Upmix global control that balances the stereo and surround mixes

The output trims also include an LFE stage on UM226.

What does UM226 add for the low end?

The 5.1 version has two extra tools for the LFE speaker.

LoAir adds a harmonic an octave lower, which Waves describes as useful for rumble and FX.

A 4th-order low frequency filter feeds the LFE channel.

If you only need stereo, the plugins also work for stereo-only remixing. You can widen the image, control the lows and shape the punch without going to surround.

Formats and system requirements

On Mac, the plugins run on macOS Monterey 12, Ventura 13, Sonoma 14 and Sequoia 15 in VST, AU and AAX formats.

On PC, they need Windows 10 or later and come in VST and AAX formats.

That covers the usual hosts for in-the-box surround work, since the same plugins load as a VST, AU or AAX insert on the stereo track or bus you want to upmix.
