Abstract
Audio system height channel up-mixing that is configured to develop two or more height channels from audio sources that do not include height-related encoding. The up-mixing involves determining correlations and normalized channel energies between input audio signals. At least two height channels (e.g., left and right height audio signals) are developed from the correlations and normalized energies.
