1. Calculate the size of a 54 second audio file sampled at 22.5 KHz using a sample depth of 16 bit. The audio is mono.

2. Calculate the size of a 2 minute 45 second stereo song sampled at CD quality using a sample depth of 16 bits.

3. Jack has recorded a 4 minute 35 second song. He exports 2 different versions, as follows: Version A - 22.5KHz, sample depth 16 bit stereo Version B - 44.1KHz, sample depth 12 bit mono

Calculate the file size of both versions and say which would be the smaller file

4. Calculate the size of an uncompressed 22 second video clip captured at 12 fps. The video resolution is 640 x 480 with a colour depth of 16 bits.

5. A video is captured at 24 fps and is 14 minutes 12 seconds in length. The video resolution is 1024 x 768 pixels and each pixel is represented using 24 bits. Assuming the video is uncompressed, what will its file size be?   Calculate the size of an 40 second audio file sampled at 44.1KHz using a sample depth of 16 bit. The audio is mono.
