To facilitate the training process, a proprietary computer-based software program called “How to Listen” was developed by Harman software engineers Sean Hess and Eric Hu. The software runs on both Mac and PC computers, and can play both stereo and multichannel music files. A real-time DSP engine built into the software application allows real-time manipulation of sound quality attributes in response to the listeners’ responses and performance.
