Crosstalk cancellation can expand the stereo soundstage from ±30° to ±90°

Evidence

Although intended for the reproduction of binaural, head-related recordings, listening to conventional stereo recordings is possible, in which case, what does one hear? It depends on how successful the crosstalk cancellation is, because what is happening is that hard-panned L and R images are delivered to the respective ears as isolated signals. The perception can be of images to the sides of the listener. In the extreme, the normal ±30° stereo soundstage expands up to ±90°, which is not subtle. — Toole, Floyd E, Sound reproduction- the acoustics and…, 306

• SHARE: Worth sending to an audio engineer friend who plays with DSP spatial processors — the ±30° to ±90° expansion figure is a nice concrete benchmark for judging such effects.
