As a musician learning a piece of music, imagine being able to take a musical recording and selectively mute certain instruments or all instruments except for a desired one for playback to aid you in your practice sessions. The goal of this research project is to allow for this selective muting of instruments on any general recorded song, partially with the aid of having the musical score for the instruments of interest on hand. This form of muting from a recording is known as instrument separation in the context of signal separation from a mixture of recorded signals and our goal is to develop appropriate adaptive time-frequency filters and signal source separation techniques to be able to accomplish this separation task. The end result would be a score-informed mono (or stereo) instrument separation that will allow for musicians to practice along by mimicking a single instrument or to accompany the rest of the song by suppression an individual instrument to allow for "music

作为一名学习一段音乐的音乐家，想象一下能够有选择地将某些乐器或所有乐器静音，除了想要播放的乐器，以帮助你在练习过程中。本研究项目的目标是允许对任何一般录制的歌曲进行这种选择性的乐器静音，部分地借助手头上感兴趣的乐器的乐谱。在从记录的混合信号中分离信号的背景下，这种形式的录音静音被称为仪器分离，我们的目标是开发适当的自适应时频滤波器和信号源分离技术，以能够完成这种分离任务。最终的结果将是一个有乐谱信息的单声道（或立体声）乐器分离，这将允许音乐家通过模仿单个乐器来练习，或者通过抑制单个乐器来伴奏歌曲的其余部分，以允许“音乐”
