Abstract

In the currently evolving spatial audio paradigm, an ever-present question is how to meaningfully reproduce two-channel stereo recordings on multichannel systems designed for 3D or ‘immersive’ formats. The key challenge is to ?nd a way of reproduction that, on the one hand, satis?es listeners’ expectations on immersion and, on the other hand, remains faithful to fundamental characteristics of the original recording, such as, e.g., tonal balance, image stability etc. To pragmatically enable a ?exible shaping of these characteristics, an attractive signal chain is to ?rst process the stereo signal into a number of intermediate, spatially decoded, channels that may subsequently be ?ltered and combined into output speaker channels. This paper presents some insights and results from explorations in this domain, with a focus on design principles towards low-artifact nonlinear stereo upmixing.
