Abstract

In this paper, we propose a method for manipulating vocal sound in mixed music signals using side information. In the proposed method, fundamental frequency (F0) of the vocal signal is used as side information. F0 information is estimated from the target signal before being mixed with backing track signals. After receiving the mixed music signal, vocal sound manipulation is performed using a comb filter using F0 information. The performance was evaluated using signal-to-noise ratio (SNR) as well as PEAQ. Then, we evaluated influence of quantization bit rate on average error of F0 information.
