AB  - In layout-independent audio production, content is produced independently from the number of channels and their location, so that it can be played-back in different multichannel setups. In such contexts, sound is monitored through a playback system that might differ from the potentially many exhibition layouts. Signals combine to the outputs of each playback system in a different way and may produce clipping in some loudspeakers. A method is presented for detecting and quantitatively estimating clipping in the output stage of such systems, based on a suitable definition of a worst-case loudspeaker layout, and associated audio scene rotation and decoding. Practical examples are provided to validate the algorithm.
