Abstract
Our novel audience service for live events uses supplementary audio content presented through transparent headphones to enhance the traditional audio playback of a PA loudspeaker system. The service requires to estimate the propagation delay of sound waves from the PA loudspeakers to the listener in order to individually delay the supplementary audio content and temporally align it with the PA playback. This paper compares two different correlation-based methods regarding their computational complexity and their performance in estimating the above mentioned time delay using realistic recordings of music and speech samples. Additional measures, that make the estimation more robust, were developed and are also presented. Typical issues like tonal components, room reflections, crosstalk and a large number of correlation lags are addressed.
