Lab 1: Elementary Music Synthesis
1. Goals
The goal of this lab is to construct physically meaningful signals mathematically in MATLAB using your knowledge of signals.
You will gain some understanding of the physical meaning of the signals you construct by using audio playback.
We also hope that you have fun!
2. Lab resource
- PC with Matlab
- Sound card installed in PC
- Headphone set
2. Background
In this section, we explore how to use simple tones of various frequencies to compose a segment of music. In addition, you will work on improving the perceived quality of the sound you created.
Each musical note can be simply represented by a sinusoid whose frequency depends on the note pitch. In this lab, you will use a sampling rate of 8 kHz.
There are seven natural notes: A, B, C, D, E, F and G. After G, we begin again with A. Music is written on a "staff" consisting of five lines with four spaces between the lines. The notes on the staff are written in alphabetical order, the first line is E as shown in Figure 1. Notes can extend above and below the staff. When they do, ledger lines are added.
