Manufacturer "DBX"
dbx is a noise reduction technique for audio recordings that was developed in 1971 by dbx, which is now part of the Harman group.
Like most analogue noise reduction systems, DBX works according to the compander principle. With dbx, the entire frequency spectrum of the audio signal is compressed at a ratio of 2:1 before recording and expanded at the same ratio during playback. Due to the high compression factor, dbx offers noise and background noise reduction of up to 40 dB. With high-quality tape recorders, dynamics can be achieved that even exceed those of a 16-bit digital recording. In contrast to some other compander systems, such as Dolby, compression and expansion are based on a linear characteristic. As a result, the system works level-independent - an exact calibration of the playback level is not required.
Originally dbx was developed exclusively for the professional market to increase the dynamics of high-quality tape machines in studios. In the early days there was only one variant of dbx, which therefore only bore the name dbx. A few years later, the company recognized that with minor modifications, the system could also be used successfully in tape recorders and cassette recorders for home use. This is what dbx II was developed for. The original dbx, intended for professional use, was referred to as dbx I from that point forward to clearly distinguish it.
