Abstract

One embodiment provides a computer-implemented method that includes determining directional sounds from a content mix using a machine learning unmixing model. The directional sounds are panned in an upmixed signal. Signal-dependent upmixing gains for specific frequency bins are computed on a frame-basis using a machine learning model for the upmixed signal. Dedicated voice clarity gains are computed using a hearing impairment model for multiple hearing-impaired profiles for achieving dialog enhancement. The signal dependent upmixing gains and voice clarity gains are transmitted as metadata with a downmixed signal representing the content mix.
