RIAA equalization is a specification for the recording and playback of phonograph records, established by the Recording Industry Association of America (RIAA). The purposes of the equalization are to permit greater recording times (by decreasing the mean width of each groove), to improve sound quality, and to … Visa mer 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 … Visa mer Origins of pre-emphasis Equalization practice for electrical recordings dates to the beginning of the art. In 1926, Joseph P. Maxwell and Henry C. Harrison from Bell Telephone Laboratories disclosed that the recording pattern of the Visa mer Telefunken and Decca founded a record company (Teldec) that used a characteristic which was also proposed for German DIN … Visa mer The official RIAA standard defines three time-constants with pre-emphasis rising indefinitely above 75 μs, but in practice this is not possible.
