AQA GCSE · Question 13.2 · Fundamentals of data representation
State one disadvantage of a high sample resolution.
State one disadvantage of a high sample resolution.
How to approach this question
A high sample resolution means more bits are used for every single sample. If you use more bits to store the same amount of information (in this case, one second of sound), what is the overall effect on the amount of storage space required?
Full Answer
It increases the file size.
While a high sample resolution results in higher quality audio because it captures the amplitude of the sound wave more accurately, its main disadvantage is that it **increases the file size**. Since more bits are used to store each sample, the total amount of data required to represent the sound file becomes larger. This means it will take up more storage space and require more bandwidth to stream or download.
Common mistakes
✗ Stating that it reduces sound quality (it improves it).
✗ Confusing it with sample rate and talking about the number of samples.
