Title

Make your own accompaniment: Adapting full-mix recordings to match solo-only user recordings

Abstract
We explore the task of generating an accompaniment track for a musician playing the solo part of a known piece. Unlike previous work in real-time accompaniment, we focus on generating the accompaniment track in an off-line fashion by adapting a full-mix recording (e.g. a professional CD recording or Youtube video) to match the user's tempo preferences. The input to the system is a set of recorded passages of a solo part played by the user (e.g. solo part in a violin concerto). These recordings are contiguous segments of music where the soloist part is active. Based on this input, the system identifies the corresponding passages within a full-mix recording of the same piece (i.e. contains both solo and accompaniment parts), and these passages are temporally warped to run synchronously to the soloonly recordings. The warped passages can serve as accompaniment tracks for the user to play along with at a tempo that matches his or her ability or desired interpretation. As the main technical contribution, we introduce a segmental dynamic time warping algorithm that simultaneously solves both the passage identification and alignment problems. We demonstrate the effectiveness of the proposed system on a pilot data set for classical violin.
