Music & Audio Advice Synthesis and Sound Design Questions and Answers

Question 1

In subtractive synthesis, what is the primary function of a low-pass filter?

Accepted Answer

To remove high-frequency content above the cutoff point.

Answer

To add new harmonic content to a simple waveform.

Answer

To control the overall volume contour of the sound over time.

Answer

To create vibrato by modulating the oscillator's pitch.

Question 2

A sound designer is creating a lush, atmospheric pad sound. They want the sound to fade in slowly when a key is pressed, remain at a steady volume while the key is held, and then fade out gradually after the key is released. Which ADSR envelope settings are most appropriate?

Accepted Answer

Slow Attack, High Sustain, Long Release

Answer

Fast Attack, Low Sustain, Short Release

Answer

Fast Attack, High Sustain, Short Release

Answer

Slow Attack, Low Sustain, Long Release

Question 3

Which of the following describes the most common method for creating a classic vibrato effect on a synthesizer?

Accepted Answer

Routing a low-frequency oscillator (LFO) to modulate the oscillator's pitch.

Answer

Routing an envelope to modulate the filter's resonance.

Answer

Routing a low-frequency oscillator (LFO) to modulate the amplifier's level.

Answer

Routing a high-frequency oscillator to modulate the filter's cutoff.

Question 4

In the context of FM (Frequency Modulation) synthesis, what are the respective roles of the 'carrier' and 'modulator' oscillators?

Accepted Answer

The carrier produces the audible tone, and the modulator alters its frequency to create new timbres.

Answer

The carrier generates the initial waveform, and the modulator filters it.

Answer

The carrier controls the pitch, and the modulator controls the amplitude.

Answer

The carrier is a low-frequency oscillator, and the modulator is an audio-rate oscillator.

Question 5

A producer wants to design a sound that continuously evolves by morphing through a series of different complex harmonic shapes. Which type of synthesis is specifically designed around this concept of scanning through a sequence of single-cycle waveforms?

Accepted Answer

Wavetable Synthesis

Answer

Subtractive Synthesis

Answer

Physical Modeling Synthesis

Answer

Additive Synthesis

Question 6

A synthesizer patch is using a square wave oscillator. To make the sound thinner and more 'reedy' without using a filter, which parameter specific to a square/pulse oscillator should be adjusted?

Accepted Answer

Pulse Width

Answer

Oscillator Sync

Answer

Fine Tune

Answer

Ring Modulation
