It is common to fin equalisers with seven or ten frequency bands. The frequency range is subdivided into frequency bands that can be emphasised or adjusted down. These allow the frequency spectrum to be controlled much more finely. ✔ Balance: Emphasise sound from the left or right.Įxternal, separate equalisers are also used in the Hi-Fi sector – and far more often in recording technology.✔ Bass: This tone control lets you boost or dampen low frequencies.✔ Mid-range: Emphasis or reduction of medium frequencies.✔ Treble: You can emphasise high frequencies or turn them down.Other common functions and controls that are useful compared to the loudness button are sound controls:
The annual Dynamics Range Day has been dedicated to this topic for some years now and protests against such sound falsifications in a self-proclaimed “Loudness War”. What seems to improve the sound of bad mp3 files with strong compression seems to improve the sound, but many sound purists reject it because the original recordings are changed considerably.
If this is activated, trebles and especially basses are raised. The controversial loudness key is particularly popular with low-cost devices. How extensive the options are depends on the manufacturer and version. One or more sound image adjustment options are integrated in most stereo amplifiers. We explain the role these controls play in building the sound image and explain what needs to be considered when adjusting your sound.
There are equalisers available as fixed knobs or as app- and software-based tone controls. The structure of such equaliser functions varies depending on the device type and manufacturer. With an equaliser, aka tone control, you can adjust the sound pattern to your personal preferences or adapt it to specific room acoustics.
