Binaural processing, Ambiophonics, and the Haas effect are some of the most popular methods of achieving 3D audio, virtual space, and wide mixes. However, for commercial music applications Binaural audio is limited by its HRTF and headphone dependency; Ambiophonics by its cross-talk cancellation and a listening sweet-spot; and the Haas effect by its hard pans. To solve this, this paper examines the recently developed Duplex Panner technique to better understand its cross-platform capabilities for playback in both headphone and loudspeaker systems. A subjective experiment comparing processed and unprocessed versions of the same material, along with an in depth analysis of the effects on phase and its psychoacoustics implications will help define the limitations of the Duplex Panner algorithm.
