With surround and immersive becoming increasingly important, upmixing from legacy stereo audio to these formats is essential. The UM225/UM226 plugins convert stereo audio to 5.0 or 5.1 surround simply and effectively—whether upmixing an entire film or TV show, or just the music.

The UM upmixers cover your conversion needs with 8 modes to spread various types of program material intelligently to L/R and L/R surround speakers, and surround-stage fine-tuning controls.

Seamlessly bring audio from stereo to rich surround

When your goal is to transition audio from its original stereo mix to full-on 5.0 or 5.1 surround, you want to retain that mix's original character - its relative positioning in space, its levels, and the overall "feel." That's why Waves designed the UM225/UM226 plug-ins. You can upmix all sorts of content from stereo to surround - without compromising sound quality. Whether you're a sound designer who wants to use stereo effects on surround soundtracks, a keyboardist wanting to output your virtual instruments in 5.0 or 5.1, a post-production specialist wanting to enhance LFE effects, a recordist wanting to bring stereo to surround in real time - or anywhere outside and in between - the Waves UM225/UM226 will be a welcome, time-saving addition to your plug-in arsenal.

Waves' patented processes deliver exceptional sound-quality

To achieve the incredible sound with the UM225/UM226 plug-ins, Waves employed patented center and rear channel extraction processes and blended it with an LFE channel enrichment process. The result is improved surround imaging with a wider soundscape and better separation. As you'd expect from Waves, the plug-ins are top-of-the-line, and give you a range of control to tweak the mix extraction to perfection. There are profile modes for music and movies, LFE channel LoAir enrichment with cut-off frequency control, adjustable rear-channel ambience and delay, an intuitive surround graph for you to work with, and much, much more.

““UM225 and UM226 are fantastic for interpreting stereo spreads into surround. They were my go-to’s when remixing Rush’s albums from stereo to surround – the UM225 to upmix stereo pads and synths in order to get some spread throughout the entire field, the UM226 to get some extra sub action. “
