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.

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

Stereo recordings intended for playback over two loudspeakers have been the standard format for the majority of listeners in particular in the home and consumer area for many decades. In recent years and with the advent of surround sound, the playback hardware transitioned from classical two speaker hi-fi systems towards multifaceted integrated sound bars and surround speaker setups but music is still nearly exclusively produced and distributed in a two channel stereo format and listeners can not directly take benefit from multi-channel loudspeaker setups.

The process of generating additional loudspeaker signals from source material with fewer channels than available speakers is called upmixing. Typically, this means to convert 2-channel recordings into multi-channel surround formats. The developed algorithm is based on the description of a stereo or multi-channel recording as the weighted sum of direct signal sources overlaid with an uncorrelated ambient signal and incorporates the following processing steps:

  1. The azimuth position or panning coefficients of the sources are estimated under the assumption that only one dominant source is active at a single time-frequency instant.
  2. The direct and ambient components are separated with the knowledge of the panning coefficients.
  3. Having the separated signals with related source positions it is possible to remix the original content targeting any different loudspeaker configuration.
