ADC & DAC 1 Wavetable Synthesis

The 15-pin connector on the back of a standard sound card can be used as a Musical Instrument Device Interface, or MIDI port.

This port is designed to take digital signals produced by MIDI compatible instruments, such as a synthesizer, and record or play back the sounds through the computer.

Using the MIDI format, sounds can be created in one of two ways:

• FM Synthesis
  
  
• Wavetable Synthesis
  
  
• FM Synthesis

Using this technique, instrument sounds are created by small hardware devices called oscillators.

Synthesizers often utilize this technique. Because the sounds are produced entirely through electronics, they sound noticeably artificial.
