Question

An audio CD uses 40960 samples per second, with 16 bits being used per sample.

The music being sampled uses two channels to allow for stereo recordings.
Calculate the file size for a 1024 second recording. Give your answer in MiB.

Answer 1

The file size for a 1024 second recording can be calculated as follows:

40960 samples per second * 16 bits per sample = 655360 bits per second

655360 bits per second * 2 channels = 1310720 bits per second

1310720 bits per second * 1024 seconds = 1342177280 bits

1342177280 bits / 8 bits per byte = 167772160 bytes

167772160 bytes / (1024 * 1024) = 160 MiB

So the file size for a 1024 second recording would be 160 MiB.
