We propose an MPEG-1 Layer III conforming audio codec for multiple generations (cascaded) compression without loss of perceptual quality. Previous research addressing this topic mainly focused on less complex coding schemes like MPEG-1 Layer II. In our paper, the techniques proposed in those approaches are extended to comply with Layer III's advanced features such as hybrid filtering, block switching, and bit reservoir based processing. A prototypic implementation including extensive listening tests shows the feasibility of perceptually stable cascaded Layer III compression.
