Sound Representation Flashcards
What is the sample rate?
The rate (number of times in a given time period, normally a second) that a ‘sample’ of the analogue sound wave is taken to represent the sound in digital format
What is bit depth?
The number of bits available to represent each sample. A higher bit depth means that a greater range of sounds can be represented.
How would you improve the quality of a digital sound file?
Increase the bit depth (allowing a greater range of sounds to be represented)
Increase the sample rate (giving a truer representation of the original sound wave)
Why is analogue sound better than digital?
Analogue sound is represented as free flowing waves rather than being limited to the sample rate of digital, Digital sound is therefore a more limited version as the sound patterns’ frequency cannot exceed the sample rate of the speaker.
