There are some techniques that can reduce these storage requirements. Sound data typically has a lot of redundancy and can be compressed, either using compression algorithms such as those used for computer data, or specialized algorithms specifically optimized for sound data. The coding schemes mentioned above were assumed to be linear; that is, the digitized values were proportional to the sound intensity. Research shows that the human ear is less able to detect differences in sound level for very loud and very quiet sounds.
