Introduction

This project aims to accurately detect the pitches and instruments of a signal. To accomplish this, we intend to record and analyze the entire range of a few instruments, and then use this analysis to decompose monophonic, or one instrument, and polyphonic, or multiple instrument, signals into their component instruments and pitches. To keep the program managable, we will limit the polyphonic signals to three instruments.

The applications of this project are far reaching, at least within the realm of musical instrument signal processing. A better understanding of musical timbre and tone is to be gained from the analysis of each instrument, and more specifically by comparing the signals produced by different instruments on the same pitch. Another, more practical goal of the musical instrument recognition project is automatic music transcription, or music to MIDI conversion.

Definition of a lens

Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.
