We transform classical music from stereo into immersive audio formats

Schroeder-Upmix is the solution to upmix stereo and surround masters into immersive/3D audio formats (e.g. Dolby Atmos 7.1.4), specialized in the high demands of the aesthetics of classical music. It was developed starting in 2018 and comes to use at the Digital Concert Hall of Berliner Philharmoniker, on immersive album releases by labels as Deutsche Grammophon, Warner Classics and Sony Classical, as well as in 5.1 for broadcast and for cinema trailers.

Customized upmix from stereo or 5.1

Every source material is different. Schroeder-Upmix includes many parameters that allow us to bring the upmix to a realistic 3D audio image, combined with enveloping, captivating immersivity.

Like a discrete immersive mix

Our ambition is to sound like a discrete 3D mix from a multitrack. Comparisons have shown that Schroeder-Upmix even makes real 3D mixes obsolete in many situations.

Downmix compatible

The downmix back to stereo of Schroeder-Upmix has an extremely high fidelity to the original stereo master which speeds up the approval process. Also the downmixes from 3D systems to smaller audio setups (e.g. 5.1 Surround) achieve outstanding results.

Binauralizer advantages

Binauralized audio often sounds completely different compared to its discrete immersive mix. Schroeder-Upmix outperforms in the Dolby Atmos binauralizer and prevents from unwanted surprises.

We upmix your archive material

Not only since Apple Music included Dolby Atmos in 2021, many labels and media libraries have wanted to upgrade their archives into immersive audio. Often it is not possible to access multitracks though, and this is where Schroeder-Upmix is the way to go. We will analyze your stereo master and audibly adjust the parameters of Schroeder-Upmix until the result sounds like a real, discrete 3D mix.

We also generate hybrid upmixes, based on stems or multitrack files

Some audio productions were microphoned for stereo, but still need to appear in immersive audio. In such cases, using Schroeder-Upmix or combining it with the available audio tracks (multitrack or stems) can be of great advantage. In many cases, when there are only a few mircophone signals, Schroeder-Upmix sounds even much more convincing than if a mixing engineer despairs trying to make something immersive out of only a few audio signals.

We work in close cooperation with Teldex Studio Berlin

In order to achieve great results with immersive audio, a reliable high end control room with a multichannel speaker setup and a Dolby Atmos renderer is required. Depending on your request, Schroeder-Upmix can be performed at the 7.1.4 Dolby Atmos control room of Teldex Studio Berlin, or in other comparable rooms.
