We have developed software apps that allow a user to non-invasively match headphones to reproduce the identical spectrum at the eardrum as that from a frontal source. The result is correct timbre and forward localization without head tracking. In addition we have developed a non-individual crosstalk cancelling algorithm that creates virtual sound sources just outside a listener’s ears. Both systems reproduce binaural recordings with startling realism. The apps enable researchers and students to hear what acoustical features are essential for clarity, proximity, and preference. Listening to any type of music with our apps is beautiful and highly engaging.
