The sampling resolution (sometimes known as the sampling size) is the number of bits of memory that are used to store each sample. Sample resolutions are either 8-bit, 16-bit, 32 bit etc. 8-bit audio gives 256 different values of sound, whereas 16-bit gives thousands of different values. By now you should be able to deduce that the greater the sampling resolution, the more memory that will be used. The table below shows the memory requirements for the two sampling resolutions.
Because of the vast amount of numbers that must be stored e.g. 44,000 per second, digital audio takes up a vast amount of memory. When you are recording your own sounds you must use the lowest sampling frequency and resolution that will give acceptable standards. Answer the following questions in your jotter. 1. What would be the storage requirements be for the following conditions:
