Humans are capable of hearing frequencies as low as 20 Hz, right through to the extremely high 20,000 Hz, which equates to 20 kilohertz (kHz).Ī frequency between 20 Hz and 500 Hz would, in general terms, be considered as bass.
In simple terms, EQ is the process of boosting or attenuating certain frequencies of a given audio signal - but how exactly does it work?Įvery single sound that we hear is made up of broad range of different sound frequencies, which are measured in hertz (Hz).
When we change the bass, middle or treble on our car stereo, or select 'bass' or 'vocal booster' on our smartphone's music settings, we're actually using EQ to make our tunes sound as we want them to. Many people don't realise that we encounter and use basic forms of EQ almost every day. However, for beginners and those that are new to the concept of EQ, it can be difficult to know where to start. For audio professionals, equalisation (known in the trade as 'EQ') is a standard part of the daily workflow when recording and mixing sound.
