CTD - Post-test Review 2

What are three types of waveforms commonly used in synthesizers?

• Sawtooth, Triangle, Square

• Sine, Circular, Conical

• Sawtooth, Polyphonic, Sine

• Sine, Triangle, Polygon

What does an oscillator do?

• A. It generates a repeating wave with equidistant positive-negative displacement from the center.

• B. It generates a rapid and random fluctuation of frequency and amplitude across the entire frequency spectrum

• C. It generates a pattern moving between two pre-determined pitches

• B and C

• A and B

Quantizing is:

• The rounding of rhythms to the lowest subdivision of the beat.

• Collecting the total number of bits allocated for each recorded sample.

• Applied to a signal to correct the pitch of out-of-tune notes.

• When mechanical energy is supplied to a transducer.

A sample is: (check all that apply)

• A digital record of the amplitude of a sound signal at a discrete point in time.

• A short, note-length recording of an instrument or other sound captured and played back in various ways by electronic instruments.

• A low-cost software application easily downloaded from the internet

• The time it takes to complete one cycle of a periodic vibration

• The shape of a sound produced by a synthesizer
