The overall idea is to output an instrument sound that plays the recorded human voice with accurate pitch and duration. This is a task requiring wider range of theoretical knowledge and their utilization in the practical part of the process. As a part of study, an algorithm has been designed and developed for implementing a real-time guitar tuner using Matlab, which outputs accurate frequency of the input signal and corrects it, if it is not in a perfect intonation. This idea has been extended to convert voice data into MIDI, for which another algorithm has been developed, and also hardware has been implemented. This technology has several music-related applications and is meant for musicians of all skill levels. One could also easily perform pitch corrections/alterations on MIDI data. MIDI is also useful in many areas, where one can apply different timbres to pitches (ex. use your voice to produce a guitar sound).

Music technology and Music technology is any technology, such as a sound technology may sometimes be classed as the computer, an effects unit or a piece of software, that same thing, but they actually refer to different fields is used by a musician to help make music, especially of work, the names of which are to some extent self- the use of electronic devices and computer software explanatory, but where sound engineering may refer to facilitate playback, recording, composition, storage, primarily to the use of sound technology for media- mixing, analysis, editing, and performance.
