The Impact of Audio Reproduction Technologies on the Perceived Affective Qualities of Music

Abstract When listening to music, the playback technologies employed and acoustic listening room conditions may alter the morphology of the resulting ambient sound field at our ears. But do these differences really matter for the experience and enjoyment of music? Or are “audio medium effects” just about quality expectations that we have developed towards certain “High Fidelity” technologies? In our experiment we focused on different types of spatialization that may be used by audio media today. 306 Subjects listened to the same four recorded live music performances of different genres. The original audio material had been manipulated by means of dynamic binaural synthesis technology into a “headphones”, a “loudspeaker”, and a “simulated live concert”-version. Each subject experienced only one of the three listening conditions and had to rate the perceived emotional expression after each piece and the overall sound quality by end of the experiment. Half of the subjects were additionally instructed to pay attention to “peculiarities in audio quality due to the special audio technology used”. While the latter manipulation substantially increased perceived sound quality (regardless of spatialization type administered) it did not affect perceived musical emotions at all. Inversely, loudspeaker and live concert simulations led to significant increases in intensity on all dimensions of perceived affective musical expression. Results are discussed in terms of their implications for audio quality evalutation experiments and standards.
