Abstract

An interactive audio service provides audio editing functionality to users. In the service, users can control the desired audio objects to make their own audio sound using a spatial audio object coding (SAOC) scheme. However, vocal objects cannot be removed perfectly from the down-mix signal in Karaoke applications of the SAOC. Thus, in this paper, a modified SAOC scheme with harmonic extraction and elimination structures are proposed. The proposed scheme removes vocal objects using their harmonic information. In addition, statistical modeling method is applied to reduce bit rates of the information. Subjective and objective evaluation results show the proposed scheme is superior to the conventional ones which are the normal SAOC and the nonnegative matrix factorization (NMF) algorithms.
