Short explanation of RIAA equalization.

The RIAA equalization curve was intended to operate as the

global industry standard for records since 1954. However, it

is almost impossible to say when the change actually took

place.

RIAA equalization is a form of pre-emphasis on recording

and de-emphasis on playback. A recording is made with the

low frequencies reduced and the high frequencies boosted,

and on playback the opposite occurs. The net result is a at

frequency response, but with attenuation of high frequency

noise such as hiss and clicks that arise from the recording

medium. Reducing the low frequencies also limits the ex-

cursions the cutter needs to make when cutting a groove.

Groove width is thus reduced, allowing more grooves to t

into a given surface area, permitting longer recording times.

This also reduces physical stresses on the stylus which

might otherwise cause distortion or groove damage during

playback.
