Music & Audio Advice Music & Audio Advice Synthesis and Sound Design Questions and Answers 2 — Questions and Answers
Question 1: What type of synthesis uses pre-recorded audio samples as its primary sound source?
- Wavetable synthesis
- Sample-based synthesis (Correct answer)
- Granular synthesis
- Additive synthesis
Correct answer: Sample-based synthesis
Sample-based synthesis plays back recorded audio snippets that can be pitched, looped, and layered to create new sounds.
Question 2: In subtractive synthesis, what is the role of a resonance control on a filter?
- It increases the overall volume of the signal
- It emphasizes frequencies near the filter's cutoff point (Correct answer)
- It adds additional harmonic overtones to the oscillator
- It controls the speed of the filter envelope
Correct answer: It emphasizes frequencies near the filter's cutoff point
Resonance boosts frequencies around the cutoff frequency, creating a pronounced peak that gives the sound a sharper, more vocal quality.
Question 3: Which envelope parameter determines how quickly a sound reaches its sustain level after the initial attack?
- Attack
- Decay (Correct answer)
- Release
- Hold
Correct answer: Decay
The decay parameter controls the time it takes for the sound to fall from the peak attack level down to the sustain level.
Question 4: What is a common use of ring modulation in sound design?
- Creating smooth pad textures
- Generating metallic and bell-like timbres (Correct answer)
- Adding subtle chorus effects
- Producing clean bass tones
Correct answer: Generating metallic and bell-like timbres
Ring modulation multiplies two signals together, producing sum and difference frequencies that result in characteristically metallic and inharmonic tones.
Question 5: In FM synthesis, what happens when you increase the modulation index?
- The sound becomes quieter
- The sound becomes more harmonically complex (Correct answer)
- The carrier frequency shifts upward
- The attack time gets shorter
Correct answer: The sound becomes more harmonically complex
A higher modulation index causes greater frequency deviation in the carrier, generating more sidebands and a brighter, more complex timbre.
Question 6: What does a vocoder do in the context of sound design?
- It reverses audio playback in real time
- It imposes the spectral characteristics of one sound onto another (Correct answer)
- It converts MIDI data into audio signals
- It automatically tunes vocals to the nearest pitch
Correct answer: It imposes the spectral characteristics of one sound onto another
A vocoder analyzes the frequency spectrum of a modulator signal and applies that spectral shape to a carrier signal, often used to make synths sound like speech.
