Development of a Multimedia Learning Module Covering the Field Perceptual Audio Coding

An electronic learning module covering the field ?Perceptual Audio Coding? (famous representive: MP3) was specified, designed and implemented by means of the multimedia software Macromedia Director. The presented program is split into different modules. These include: (1) An auralization of the filterbank implemented in MP3 (2) simulations of various classic psychoacoustic experiments (mainly masking) for three different music styles. Other audio examples exhibit (1) a comparison of the sound quality of a Fraunhofer MP3 codec at different bitrates and (2) a comparison of today?s most important audio and speech codecs (like WindowsMediaEncoder and Real9) at different bitrates and (3) audio examples and explanation of typical error signals introduced by perceptual audio coding. Finally a structured explanation of the mode-of-operation of an MP3 encoder and technical papers with further references to publications on perceptive audio coding were included in the presented software.
