What is the SCHOEPS Mono Upmix plugin good at?

The SCHOEPS Mono Upmix can generate Stereo and even LCR channels from any mono signal and works great on voices in Post Production, synth in music production, as well as bass, guitars, drum room mics, vocals, etc.

It adaptively extracts the diffuse sound in the mono input signal to create an upmix signal. As the diffuse sound should always be reproduced decorrelated on different stereo channels, the up-mixed signal sounds more natural than the original mono track.

The Mono Upmix is often superior to a reverb as it doesn’t add reverb but uses the present diffuse sound.

Furthermore, it’s possible to control the perceived source distance and panning position by generating early reflections.

The Mono Upmix plugin performs great with mono location sound dialogue as well as spot microphones in a music recording.


  • Upmix mono → Stereo and LCR (2ch or 3ch)
  • Control perceived source distance and panning position
  • Boost diffuse the room/reverb portion of the signal

    I haven't left many plugin reviews but wanted to leave my $0.02 here. Fact is, I buy more plugins than I use - or know how to use. Mono Upmix, however, is a plugin that I really like for mono tracks.… Read More
  • It's fantastic!

    Works extremely well. Great as the first step for placing things in a perceptual environment for a binaural mix.
  • Another tool

    by Paul Misty
    Good for mono recordings that need some room while reverb doesn't get good results. This one really feels like it was recorded with 2 mics.
  • Great Plugin

    by Barry Hufker
    Normally when I record classical music, I use a stereo mic'ing technique. But for a recent concert video I had to mic a flute and guitar duo individually. It was a good sound, but it didn't have the… Read More
