Question 2

What happens to a sawtooth wave's timbre when you apply a low-pass filter and gradually reduce the cutoff frequency?

Accepted Answer

It becomes progressively darker and smoother

Answer

It becomes brighter and more aggressive

Answer

It splits into two detuned oscillators

Question 3

In additive synthesis, how would you construct an approximation of a square wave?

Accepted Answer

By summing sine waves at odd harmonics with amplitudes decreasing as 1/n

Answer

By summing sine waves at all harmonics with equal amplitudes

Answer

By summing cosine waves at even harmonics only

Answer

By frequency-modulating two sine waves

Question 4

What is the primary audible difference between a triangle wave and a sine wave?

Accepted Answer

A triangle wave has a slightly brighter, more present tone due to weak odd harmonics
