Accepted Answer

Sine Wave

Answer

Sawtooth Wave

Answer

Square Wave

Answer

Triangle Wave

Question 2

A sound designer wants to create a bright, buzzy, and aggressive synth lead. They know that a harmonically rich waveform would be the best starting point for subtractive synthesis. Which waveform should they choose?

Accepted Answer

Sawtooth Wave

Answer

Triangle Wave

Answer

Sine Wave

Answer

Square Wave

Question 3

What is the primary timbral difference between a square wave and a triangle wave, given that both are composed only of odd-numbered harmonics?

Accepted Answer

The triangle wave's harmonics decrease in amplitude much more rapidly than the square wave's.

Answer

The triangle wave's harmonics are louder and more prominent.

Answer

The square wave includes a small amount of even harmonics.

Answer

The square wave's fundamental frequency is always an octave lower.

Question 4

An artist is using a synthesizer and modulates the 'duty cycle' of a pulse wave oscillator. What timbral change will they hear as they sweep the duty cycle away from 50%?

Accepted Answer

The sound will become thinner and more nasal as different harmonics are canceled out.

Answer

The sound will become lower in pitch.

Answer

The sound will become brighter and contain all even harmonics.

Answer

The sound will transform into a pure sine wave.

Question 5

Which of the following describes the harmonic structure of a perfect square wave?

Accepted Answer

A fundamental frequency with only odd-numbered harmonics.

Answer

A fundamental frequency with all integer harmonics (even and odd).

Answer

A fundamental frequency with only even-numbered harmonics.

Answer

Only a fundamental frequency with no harmonics.

Question 6

A producer is attempting to create a sub-bass patch. To ensure a clean and powerful low-end without introducing complex overtones that might clash with other instruments, which waveform is the most suitable choice?

Accepted Answer

Sine Wave

Answer

Sawtooth Wave

Answer
