• Band-pass filter

• Notch filter

What does ADSR stand for in the context of an envelope in subtractive synthesis?

• Attack, Delay, Sustain, Release

• Attack, Decay, Sustain, Release

• Amplitude, Decay, Sustain, Resonance

• Attack, Depth, Speed, Resonance

Which part of the ADSR envelope determines how quickly a sound reaches its maximum level after a key is pressed?

• Attack

• Decay

• Sustain

• Release

What is the primary role of an LFO (Low Frequency Oscillator) in subtractive synthesis?

• To generate audible sounds

• To modulate various parameters of the sound over time

• To filter out unwanted frequencies

• To increase the overall volume of the sound

Which parameter of an LFO determines how fast it modulates the sound?

• Waveform

• Notch filter

Which oscillator waveform is typically used for creating flute-like sounds in subtractive synthesis?

• Sine wave

• Square wave

• Sawtooth wave

• Triangle wave

What does the sustain level of an ADSR envelope represent?

• The time it takes for the sound to fade out after a key is released

• The initial volume level when a key is pressed

• The volume level maintained as long as the key is held down

• The time it takes for the sound to reach its peak level
