Space Explorations: Broadening Binaural Horizons with Directionally-Matched Impulse Response Convolution Reverb

More people are listening with earphones than in the history of recorded music. But earphones locate typical audio claustrophobically in-and-around the listener's head due to an absence of localizing information the brain requires to externalize sound. When combined with recent trends to highly compress music, the results are an unnatural and unhealthy listening experience—a dumbing-down of the auditory faculty. But the rise of earphones has also brought binaural technology onto the radar. While most binaural music productions have been limited to capturing live performances within a single space, the pioneering application of directional binaural impulse response convolution reverb paired with directionally-matched binaural studio recordings restores acoustically diverse spatialization to music.
