Forum : Producing Help : prob resonating bass notes

Hi,
I got some problems with low sub or low bass, on certain notes it becomes very loud, like strong resonance.
Don't know if it's due to my non acousticaly treated room or if there a plug-in (phasing problem?) that can stop that resonance thing. 
On the track I'm curently working it's a bass played on A# that resonate too much compare to the other note bass with is played on F.
There's some tables that give each note it's freq.

I don't know if there's some particular notes to avoid, cause of it's freq range, if you don't want to have some bad surprise when you play your tracks in a club or what ever??

It can be a lot of things: resonance caused by the frequency response of your speakers, resonance in your room (ondes stationnaires),...If your speakers are put on a wooden table, it can be the resonance of the table. I had this problem with a frequency between 100-110 Hz. Then you can try to put your speakers on stands.

I checked with spectrum and a eq, it seems that the freq range that is problematic is round 110-120Hz.

try putting 2 towels under your speakers.

also hanging up thick carpet like pieces of cloth or mousse on strategic places can do wonders, just hang one or two on some flat surfaces, usually straight in front or behind you or to the left and right of your head and listen to the same track to see if they make a difference.

laying a blanket on the desk the speakers are on can help cancel out monitor-to-tablesurface-to-ear reflections

iif you want to avoid these things, build your studio in an asymetric room, without parallel walls. then put absorbing materials in it (for basses, you'll need large thin wooden plates on the walls/ceiling and basstraps in the corners).

oook so it would be the acoustic of my room then? nothin else involved
So if I understand I don't have to worry about that if I want to play live that same track. In a club it won't react the same as the club has an other room shape?!
Acoustic treatment is a must but if you want to do it proply it cost quiet a lot... it will wait a bit for me.

it could also be the table or the fact that the speakers or yourself are close to a wall, but you should pay attention to it=> ifit causes you to mix too little bass in your tracks, you will hear it when playin on other soundsystem. i'd say to check with a frequency sweep, and note the freqs that stand out. then compensate them on you monitors, ot with an eq plugin on the monitoring (disable it when recording your track, because it's only valid for you soundsystem/room).
off course, first find out if it get's better when placing your speakers at another place in the room.

Need more INPUT ...
You should also say if it'sn hardware keyboard or a VSTi that generate
the bass.  Maybe you should post a sample of the problem.
If we all listen to it and all have the problem, then it maybe can be fixed with equalization.
Because with some bass samples (or VSTi generated notes), you can meet weird sounds behavior.

some vst bassess do indeed resonate or sound more full at a certain key. you can fix that with some compression, limiting or maximizing, but most of all i would use velocities, making the volumes of those notes a bit less. just check with different vst basses and different presets, if they all have a resonance peak in the same key i would gues the problem is acoustics, if they resonate on different keys it could be the vst

the corners of a room can also be problematic for bass, i stacked the cardboard boxes of my speakers, pc and so on top of each other in one corner so the shape is irregular. it's an easy fix but does wonders. also like i said, one piece of thick carpet or mousse of even one square m in the right place on your walls can help immensely. just listen to a track of a proffessional artist you know very well while trying out changes in the room to see if it helps. btw even moving your couch one m back or forth or moving your speakers 20 cm back/forth can make all the difference. don't forget to listen in the place you'll be sitting while making music, cause that's where it needs to sound right.

Ok ok. some good advises here. I'll try them when I have some time to do it proply.
 May be I'll upload a sample of the track, so you guy's can test it on your setup as AiA said.

thanks ebelers

well, if you want to make sure it's your room or not, why not try listening to the same track with some good headphones? If the problem persists, its in your soft/hardware, if the prob goes away, its probably the speakers or the room...

if you are using a sin wave, then maybe try adding some square waves to it..
I saw this in a mistabishi masterclass tutorial on youtube, you should check it out. some frequencies are just louder with a sin wave than others and adding a square or saw (even if relatively silent) to it may fix that for you...
