Answers
How accurately a stored recording matches the original sound, which is limited by the number of bits used.
The length of time that passes between each measurement taken from a sound wave.
Measuring the height of a continuous sound wave at regular intervals so it can be stored as binary.
A continuously varying signal in which the wave changes smoothly rather than in separate steps.
The number of measurements of a sound wave taken each second, which affects the level of detail captured.
A device that converts a continuous input signal into a discrete digital signal that a computer can process.
The height of a sound wave at a given moment, which determines how loud the sound is.
The unit of frequency equal to one measurement, or cycle, per second.
A single measurement of the height of a sound wave taken at one particular moment in time.
The number of bits used to record each measurement of a sound wave, which affects its accuracy.
A device that converts a stored digital signal back into a continuous signal for output through a speaker.
Calculated by multiplying how often the wave is measured by the bits stored per measurement and the duration.
