Properties of Sound : Sampling rate, bit depth, file size, MP3 format

A number of worksheet activities :

1.Investigating MP3 Compression:
where learners chose different compression rates on a wav file to investigate fiel sizes and qualities using Audacity ( free sound editing software).

2.Sound and how to store it :
introduces sound in terms of frequency and amplitude
and how stored digitally.

3.Sound Revision Quiz :
some basic understanding of sound properties are tested, bit
depth, sampling rate and file size in bits and bytes

4.Sound in Binary :
A research quiz to explain the basic key words / principals of storing sounds

5.Sampling Sound:
A worksheet where learners can sample a wave to learn about sample rate, bit depth, denary value, binary values stored and file size in bits and bytes
