Conference Paper

Semi-Automatic Mono-to-Stereo Upmixing via Separation of Note Events

AES Conference: 2019 AES International Conference on Immersive and Interactive Audio · Paper 12 · March 2019

Abstract

A novel method for upmixing mono recordings into stereo is presented. This approach uses a source separation strategy to extract a note events from within the original mono mixture, which are clustered into individual sources by exploiting a user-interactive interface. The isolated sources can then be panned in different parts of the stereo image to create a wider spatial experience in the final version. In this work, quality of the stereo sound is evaluated by conducting a listening test, and results are compared with a similar process based on a different separation strategy. The proposed system is shown to be able to deliver stereo versions with higher audio quality and naturalness, suitable for music containing harmonic instruments or singing voices.
