Hi to everyone, just a question about a few huge sub sounds im working on.
After bringing my izotope spectrum analyser up i can see loads of enegry in the 10 and 20hz region (Way to much, if i compare it to a load of other mastered tracks)...but it takes my eq (on the sub insert) up to 50hz cut to get it to be sitting nicely, but by then the sub power has gone...The cut im doing with the eq is pretty steep as well, 36db curve.
So if i bring the eq back to about 30hz on the sub insert, i then add a cut in the group (beat & beat) i have to take this to about 25, 30hz...ive lost the power again about the spectrum analyser so showing the sub sitting in the right place.
Or if i do the cut on the master channel (instead of the group) by about 20hz im getting the results again, but lost the power.
Ive got a few other tracks where their low end hasnt been a problem at all, just one simple cut in the the 25hz region has made them sit perfect, but these new ones im working on are a bit tricky.
Should i just forget about that extra presence and carry on, or is there something im missing here?
any tips would be great
thanks |

| hvae u tried a DC remover? might be clashing sounds. also remember to mono down there (sure u have already). you should be able to eq it away with multiple eqs with hi q and lots of negative dB at various frews. depends on the daw/instrument ur using, i had to use like 5-6 eqs in serie in Reason to remove the ty low freqs and also sometimes DC removal in Reaper after exporing the wave. 36dB/oct isnt really that much when it comes to removing subs as u have to put it atleast on 40Hz for it to even work at 20Hz (one octave down), when you really want to remove it like 96dB at 30Hz would have you to put a 36dB eq on 120Hz which would remove all bass completely - you need a much higher sloped filter/eq.. worst written text ever but ok. |

wooo didnt even know anything about dc outset until today, thanks for the tips. just looking it up now...learn something everyday on here : )
yeah ive sorted the sound out with using multiple eq's but this is the 1st time ive had to do it and thought i might be doing something wrong :s
bass is defo mono, got the waves paz to tell me that, so all good there : )
thanks again

| but is the master mono below 80Hz? could be other sounds with subs too. id put on a HPF on everything but kick and bass at 80Hz or maybe even higher just to be sure. Snare could have lots of sub and help ing up... |

Hi yeah ive got a hpf on everything par the beat and bass...but the eq on my master channel ive only got to 30hz...could you go into more detail about the master mono???
thanks

| In Reason there was this stereo/mono master device that you could adjust frequence and how much stereo width youd want under and over that frequence, i usually sat it at 0% stereo (100% mono) below 80Hz and leave the setting for above 80Hz untouched (as the signal is). Some people add some stereo here to get wider sound. I dont know what daw you are using but most daws should have similar devices. maybe its called stereo-widening or something and you might have to split up your master channel to one mono and one stereo, use a HPF filter for the stereo and LPF for the mono, both at 80Hz. It really depends on the daw and device youre using. theres great VSTs for this probably too, mastering devices. Reaper has similar deivces included, also the DC remover and the sub-cut device. I also used to cut everything above 18kHz. Not sure thats any point. |

Th problem would be that you are only cutting the sub channel when everything else also has lots of energy in that region. |

| could it be that the sub is pitched too low in the first place? |
