Abstract
A modified time-domain least-squares (MTLS) finite impulse response filter design method for transforming musical notes is introduced. The method is based on a new criterion called total harmonic gain to noise ratio (THGNR) in addition to the least-squares criterion. The THGNR criterion aims to reduce the noise gain of the filter. Compared to the time-domain least-squares finite impulse response filter design method, the MTLS offers a better solution, which has low noise gain and small time-domain distortion
