Expressive modification of music recordings for realistic stimuli generation

Event Abstract Back to Event Expressive modification of music recordings for realistic stimuli generation Marco Fabiani1* 1 KTH/CSC/TMH, Music Acoustics Group, Sweden Stimuli used in music perception experiments can be roughly divided into two categories. MIDI generated stimuli have the advantage of allowing easy and precise control of single parameters, but can sound unnatural. Audio recordings, on the other hand, cannot be modified. A musician can be instructed to play the piece in different ways, but the result will always retain a certain degree of uncertainty. Our aim is to unite the flexibility of MIDI stimuli and the naturalness of real recordings through the modification of audio recordings based on a set of performance rules and the active control of the user. The audio recording is aligned with a score file containing performance rules data. It is then transformed into a time-frequency representation, and analyzed to separate each tone. New values for tempo, tone length and dynamics are computed by combining the rule data and the user’s settings. The desired modifications are achieved through the manipulation of the time-frequency representation by adding or removing parts of tones (for articulation) and changing their spectral envelope (different sound levels present different timbres), as well as by performing time stretching. The modifications should avoid noticeable artifacts and result in a performance comparable to a human performance. Conference: Tuning the Brain for Music, Helsinki, Finland, 5 Feb - 6 Feb, 2009.
