The Digital Signal

In this class we introduce digital audio signals and how to generate samples with a computer. Here's a nice old-school picture by Max Mathews, a pioneer in computer music.

The topics of this week's class are:

• Sound
• Digital Audio Signals
• The sample
• Sampling rate
• Amplitude. Resolution
• Differences between audio and control signals.

After the class you will have some exercises and a better idea of the following Pd objects:

• osc~
• dac~
• adc~

Here's how we will navigate the class:

1. Sound
2. Digital Audio
3. Digital Audio Signal
4. Samples
5. Exercises
