not the brightest spark...
Member Since: Sep 13, 2005

Guys,

I'm recording a rock album at the moment.

I want to be able to take a copy of my overheads mix and filter/e.q out all of the cymbal harshness so I can bring the snare to life by adding the overhead snare sound to the quit flat and lifeless 57 sound I have.

Is there any way to do this using a frequency analyser that will tell me the frequency of a selected sound so that I can remove it/boost it in the mix?

I have tried the noise reduction feature in audition but it sounds cheap. Cuts the wrong stuff.

I have also used a narrow sweeping e.q with a little more success.

Either way a tool that tells you the exact frequency of a given selection of audio would be of great use to me.

Any ideas?

Many thanks,

Flashy

Well, if it's a final mix of the music you can't really pick out instruments or sounds...when I need to do that I use what you said, I set a narrow Q on a sweepable parametric EQ, cut it substantially and cruz around the frequency spectrum until I find the spot that is affected by those changes the most, then mix to taste widing the Q, moving the amount of cut up or down, etc...

Unless you can find a spot where the noise is "solo" it's pretty tough to pic it out of a mixed piece.

Thanks Db,

I was just wondering if there if I can say, play a sample of a kick drum and then press a magic button that tells me exactly where it's dominant frequencies lie in numbers or pictures.

I could then use that on all the main instruments in a mix to shave off unecessary frequencies thus improving my mix separation.

Does this exist?

something like HarBal would tell you that easily.

ah yes. Harbal.

Santa has a copy in Sack for me I think.

Cheers Db.

Hoping you're well.

I haven't seen Adobe Audition, but it's supposed to be a rebranded version of Cool Edit Pro. If Audition is laid out like CEP, you should have a very good frequency analysis tool behind the "analyze" tab on the top toolbar. The Help menu can also be your friend.

Thanks chaps,

I have used it but I cant seem to figure it out. That said I have started using Voxengo SPAN which seems very good.

Freekascope is a good freebie frequency analyser. that said, I have no idea how to use a frequency analyzer effectively. I see bouncing squiggles in a logarithmic pattern and I still don't know how to judge if there is too much of one frequency, or not enough of another. None of the peaks ever look conspicuous enough to tell me anything.

Tadpui, a lot of the frequancy analyzer's have a peak hold function that will temporarily hold the peaks of the sound which will allow you to have a quick look at them.

Sometimes it may not be the peak or valley that is the problem, it could be maybe 500Hz stretch or more that is causing the problem.
