explain a filter

can someone explain a filter to me in idiot terms?

From my understanding a low pass is where you REMOVE the bass fround the sound?

There is a filter function on higher end mixers...so if filter is selected and your knob is turned all the way to the left then it will cut the bass and then bring it back in? then out...then back again?

a low pass filter removes everythin BUT bass.

low-pass. Means low frequencies pass through the filter. The knobs on mixers are called EQ (equalisation) knobs. They work just like a volume knob, except that they let you isolate certain frequency ranges. So if you turn all of the low knob down, then it's like turning the volume knob down to zero for only the low frequencies.

you could probably get a better answer if you asked in the production forum

although djs do use filers (hi-pass, low-pass and band-pass being the main ones) producers will be able to give you a more in depth answer

Interesting.

I always thought filters were equivalent of EFX. Silly noob I am.

Well, it can definitely be used as a type of effect, So while they're not equivalent, you're not totally wrong.

Think of a filter like an oil or air filter- it removes 'stuff' from the oil or air, respectively.

Filters, with respect to audio, remove certain frequencies. Basically, bass = low frequency and treble = high frequency.

low-pass filters do what it says: pass low (frequencies), eg. remove high frequencies.
high-pass filters remove low frequencies, passing only the high-frequencies.

As 'miamitranceman' said, filters can be used as an effect, particularly those which you can alter the frequency where it stops 'passing' (cutoff frequency).

They can be, but I find them to be far more useful for transitions than anything.

Actually, that was a very good explanation in my opinion. Very solid.
