Abstract
A system for providing feedback regarding detectability of a watermark message produced by a watermarking encoder includes a simulation module configured to combine at least one of a watermarked signal or an enhanced watermarked signal with a simulated environment signal that corresponds to an expected listening environment of the at least one of the watermarked signal or the enhanced watermarked signal, and output a simulated environment-modified watermarked signal corresponding to the combination of the at least one of the watermarked signal or the enhanced watermarked signal with the simulated environment signal, and a monitoring module configured to generate a watermark detectability indication based on the simulated environment-modified watermarked signal.
