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.

Summary: Introduction

Introduction to a Music Synthesizer

Our Goal

The aim of the project was to create realistic instrument sounds by means of digital signal processing (DSP). Algorithms and theories already exist for mimicking various instrument families and all revolve around modeling the instrument structure and material as well as how the instrument is played. One of the simpler algorithms is the Karplus-Strong, which produces amazingly realistic guitar sounds. Using this algorithm in combination with attack-delay-sustain-release (ADSR) concepts, we were able to synthesize some decent instrument sounds.

Next Step

The first step would be to increase our instrument library to include different instrument families. Karplus-Strong mainly works for string and some percussion instruments, which greatly limited the diversity of our virtual orchestra. This would consist of implementing different algorithms to simulate the various types of instruments. Finally, how does mimicking instruments through DSP constitute music synthesis? The next objective would be to generate random pieces of music. A plausible scheme would be to implement a first or second order Markov model to generate random pieces with musical structure but leave enough room for creativity.
