A sample is

• The tempo of the sound wave

• A measure of the amplitude at that moment

• The amount of bits needed to store the sound wave

• The information needed to reconstruct the sound wave

What sample rate is the standard?

• 22 kHz

• 32 kHz

• 44.1 kHz

• 86 kHz

The sample rate is measured over a

• minute

• second

• hour

• per track
