Forgive me, I am a newbie DJ...

I was just screwing around trying to improve my beatmatching skills, well when I mixed a record into the one I was currently playing, the beats seemed lined up pretty much right, however, the bass from kick went away. It was weird. Does anyone know why this would have happened? The bass came back when I killed the bass on the other deck.

It's completely normal. When the beats are matched in a certain way the 2 bass beats cancel each other out.

theres a thread on this.

if that happens, be more careful with ur eqs, cuz it doesnt sound very pleasant, u can semi avoid it.

sometimes if you turn the bass down from one of the tracks it will fix it

check your Eqs and make sure the bass isnt set at the same levels on both channels...

its called destructive interference - chances are you have the beats matched, but do you have the phrasing matched? your speakers can only kick a certain frequency in a certain way - to be very simplistic, think of a see-saw when you sit on one end the other goes up, think of each bass kick as you sitting on the see-saw, if the kicks arent matched correctly its like trying to match a down/up with an up/down which leaves you with a flat line...


shitty explanation but its somewhere along those lines, im sure somone else can clear it up, im somewhat not sober at the moment

actually that was a good analogy haha. yeah thats basically waht happened because sometimes you'd hear a kick then it would go away come back in, etc.

props on the drunken analogy.

to prevent, just EQ a bass in/bass out. a good place to do this is during those 16-32 bar small breaks where the bass is cut. when the bass is supposed to come back in on the original track, cut into the new bassline. its my standard way if im too lazy to be creative, but sounds great with keyed tracks

Cool. Thanks!

Also, sometimes I will have track matched up, but it will go out of synch after 10-15 seconds. And its never the same thing, I have to keep speeding it up and slowing it down. Could this be because the record is warped? Most of the time when I get two tracks beatmatched I don't have to keep fucking with the record.

interesting analogy. but just to clear things up - its called destructive phasing. destructive interference is something completely different.

as a general rule you want to eliminate destructive phasing as much as possible. destructive phasing only occurs when a frequency exists in phase and in anti phase. the sound just cancels out. using certain effects such as reverb alter the phase of the effected sound. kick drums typically phase destructively because they have alot of bass presence and theres very little difference in between songs with regards to the frequency band they tend to occupy. its mostly 50 to 150 hz. having 2 kicks go off in the mix together often causes phasing problems.

killing the bass on one tune is one solution to this problem. although its not too subtle. if you have a mixer with a filter you can close the filter of the outgoing track to minimize the amount of destructive phasing. in some cases if you mix tunes where the kicks sit in different frequency bands (i.e. a track with a subby, loooow bass drum mixed into a pvd tune where the kicks are more low mid rangey and harder) then you wont get so much phasing problems.

one way you can minimize this even further is to limit the use of phase modulation effects on 1 of the tunes (this includes reverbs, delays, tape echoes, chorus/flangers and phasers) if you do it on both channels at the same time it wont cause additional problems.

Interesting...no I dont use any effects. I have a pretty low end mixer

search my posts for more in depth explanations of what phasing is and how to minimise destructive phasing. ive got about 800 posts but at least 3 or 4 of those are essay length explanations on the subject. i think the one i did here was a bit a shit.
