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

    by James Mullen
    PA is right, this plugin is similar to what you do with bx_stereomaker, but it sounds very different as it seems to achieve its sounds in a slightly (or totally?) different way.

  • A Great 1st from Schoeps

    by phunkydiablo
    A quick test on layered strings recorded in the same room by same players/position and microphones made me fall in love with it. Some of the sessions i deal with in NYC are done fast, real fast. And… Read More
