Bass Questions

Ive read some things about freqs below 40hz being removed but would this stand true for club music? Or is it better to leave this in?

Also is it wise to simply cut all freqs up to 100Hz on a sub bass?

Yer filter's the wrong way round.

cut wherever sounds good. i sometimes cut at 100 hz sometimes 150 hz depends on the bass sounds im using and how many layers im using.

I'm just learning too, but I think most people tend to cut around 30Hz and below. This area isn't audible to the human ear and it will actually make the rest of your mix louder. You also can't hear these freqs on most monitors so it's best not to guess.

As for the sub bass, you may want to cut ABOVE 100Hz depending on the sound or if it's layer below with another mid bass sound.

Hope that helps!

nah i cut everything up too 90hz but its strange why the spectral EQ shows as sounds still going on up to 900hz. Is there any way to remove these or is that simply harmonics that EQ cant remove easily?


@Cam just made a cut at 32hz just wasnt sure if i should with dance music

@Ster im mixing in headphones so i wanted to be sure i was doing it right


Thanks guys

The first image represents my first question (about 40hz and below)


the second image represents my second question (about rolling everything over 90hz off)

indeed

hi-pass with a Q of 1.41 at 32hz on the master channel?

I dont know how much 1.41 Q is, but if there is even a slight resonance pinch, that could really screw up the low end cause its just so sensitive

Im not sure what you mean by that, here is a screen grab and MP3 sample of what it sounds like after i have applied all i talked about in here. This sound ok?



Thanks

Yea, I thought you meant boosting up the res so it spikes which would be really bad. What you have now is good

Iv read alot about mastering guys cutting freq below 32-40hz but its not always needed... Depending on the mix or sound I think you can lowpass your sub bass with eq any where or filter on the synth to suit, just depends if your layering to make room for the other bass or sounds. I also think you can hipass as little as 30hz if at all and it wont affect you kick if its off beat or sidechained (pref both imo incase the off beat sub has a tail that reaches the kick.. just because you cant hear it thought that dont mean you wont feel it in a club so its not always best to roll off every where at the bottom end with your subs

I believe the cut Q starts pinching/bulging at 1.7.

My two cents:

1. As one of the very last steps in mixing down a track, yes it's a good idea to apply a low-cut filter to the master and have it set around 30hz with a resonance somewhere around 0.7. As Mr. Maxwell mentioned, the FREQs below 30hz take up room in the mix but they aren't all that audible so it makes sense to cut them (it's also a good idea to apply a hi-cut on the master somewhere around 18khz for similar reasons).

2. Cutting all the FREQs up to 100hz would (nearly) completely nullify having a sub-bass in your track since 30hz-100hz is where the sub-bass has the most energy. You can hi-cut (not low-cut) the sub-bass somewhere around 60hz (with a gentle resonance) to prevent the sub-bass from clashing with the bass and/or to remove unwanted FREQs from the sub-bass (e.g. the 'humming'/'whirring' noise associated with the higher FREQs of a pure sine wave).

Just adding that you can cut anything below 20-30Hz (Even though I've left those frequencies in for a 'helicopter' sound effect I was going after) and shelve from the cut upward to around 200Hz on drum tracks and between 350-450Hz on your basses.



The shelf actually doesn't need to be as harsh as the one I was using on this track, either.
