What’s the frequency Kenneth?
Friday, September 1st, 2006Equalization is likely the most well known audio effect processor as it’s used in everything from your car stereo to iTunes or Windows Media Player.
The short description of what is does is to boost or cut certain frequencies out of the audio signal to get more or less bass, mid or treble in your sound.
There are various types of eq designs and each can be used to particular effect to enhance or detract from the character of your sound source.
For example, the typical radio announcer voice might have a boost in the area of 250-500Hz. Or, if you’re using a cardiod microphone, often the proximity effect will give you too much in the low frequency range and you’ll have to lower some of those frequencies to acheive a smooth sound.
In upcoming posts, I’ll begin addressing ways in which eq can help to aleviate problems in a public address situation, such as conferences.
The eq in a mixer typically occurs on a channel by channel basis and is used to boost or cut the frequencies of whatever the input signal (microphone, CD player, instrument, etc.) is.
