Say u have a centered snare. When it attacks, the right speaker gets signal of -3 dB (which is 3 decibels to the upper limit) and the left gets -5 dB... which means that the right speaker gets more signal... and you hear it more on thy right ear... which is annoying and frustrating. It fucks up the whole mix.

It's not bad idea to cut all frequencies below 60hz on all tracks EXCEPT subbassline, bassline and basskick, you would be surprised but usually even your hihats features unwanted low frequencies, when all tracks are "cleaned" your subbass have a lot more headroom and mix sounds tighter

Yeah, you often see hihats, snares or rides with huge subs going on that shouldn't be there. I always filter those out when editing the sample.

yeh true
what should i do to keep my bassdrum away from my sub and have them better seperated?
cause somehow my kick seems to make my sub stuff noisy.
and which one should you hear better the sub or the kick?

im just trying to get your opinions here.

Well, a sub should be around 60hz, a kick around 80hz, so if you EQ them well, they shouldn't conflict.

use a lowpass on your sub and a bandpass on your bassdrum (if necesarry also a highpass on your bassline) so that they stay out of each other's frequency range, it will make ur bassdrum come out more too, or allow them to be at more or less equal volume and both doing their thing.

this is some great advice.
the most inportant part is the mix, but it's also very subjective, int he actual music industry the same song could be mixed by several engineers, because there is different opnions on what freq diff inst should go too, or what sounds good at diff freq's even.
best to master the norm before you try experimenting, cuz to get them set properly is hard.
i cut off my kick at 10, and boost the kick at 60-80,
bassline at 50-70.

yeh well were talking about drums any way so doesn't matter if we go off course with this thread.
what helps a lot if you snare is too tacky to get another normal snare and distort it and put it over. works like hell. ofcourse everyone knew that but i first tried it in twelve months haha.

i jsut noticed peet wrote this...im using fl studio...when i render should i check the dithering tab? if it makes things sound fresher i assume its good...

NOT sure what the dc offset does though...??? Confused

Are you sure about this? DC offset also occurs on mono signals, so there must be a part missing in your theory.

edit: found a nice explanation of what DC offset is here: http://mnorris.wellington.net.nz/soundma...veDCOffset.html

DC offset within a sample can cause some bad inaudibel distortion. while it is inaudible it does cause stress to your ears. It also causes amplitude problems as well. If you wanna toy around with fixing samples with heavy offset download suryas bass pack and listen to the difference in amplitude and phasing of the samples with and without DC offset correction. I believe this is usually caused by the sound card during bit conversion by some kind of dither algorthm but im not sure exactly. Gaga

usually if a sample is making you sick to your stomach literaly then it probably has a large amount of DC offset so deffinitly remove it.

it probably just scans the sample and removes any DC offset it might have, that would be my best guess!!

It removes the DC offset, and thereby prevents u from having any of the problems mentioned above, so best thing is to always check that box for every sample.

actually......the BEST thing to do would be to examine each sample first......if they have a bad DC offset.....then check that box.......but if there's no problem......then there's really no need to do so.
