Sound Design Audio Synthesis Techniques 2

Question 1

What synthesis method uses mathematical operators called 'operators' arranged in algorithms, famously implemented in the Yamaha DX7?

Accepted Answer

FM synthesis

Answer

The Yamaha DX7 popularized FM synthesis, using up to 6 operators (oscillators) configured in various algorithms to produce its distinctive metallic and electric piano sounds.

Question 2

In a synthesizer's ADSR envelope, what does the 'S' stand for?

Accepted Answer

Sustain

Answer

In an ADSR envelope, S stands for Sustain, which sets the level held while a note is pressed after the decay phase completes.

Question 3

Wavetable synthesis creates movement by doing what?

Accepted Answer

Scanning through a table of stored single-cycle waveforms

Answer

Wavetable synthesis scans through a collection of single-cycle waveforms stored in a table, smoothly interpolating between them to create evolving, animated timbres.

Question 4

What is 'ring modulation' in synthesis?

Accepted Answer

Multiplying two audio signals together to produce sum and difference frequencies

Answer

Ring modulation multiplies two input signals together, producing output frequencies that are the sum and difference of the input frequencies, creating metallic or inharmonic timbres.

Question 5

Physical modeling synthesis simulates sound by doing what?

Accepted Answer

Mathematically modeling the physical behavior of acoustic instruments

Answer

Physical modeling synthesis uses mathematical algorithms (such as waveguide models) to simulate how physical objects like strings, tubes, or membranes vibrate to produce sound.
