Pro Audio Content Management System

Hi, I have my own small studio (PT24 5.1/88824/) and where I live it's a excellent option because of the price range and the advantages it gave me over other studios in the area.
Right now i'm doing SORT of Mastering, i mean I'm not a mastering engineer but here there are no options around so I took the advantage and I'm almost the only option around.
The thing is that obviously my studio is not prepared for mastering so recently I have trouble with some songs which had very bad POPS on the voice and I don't notice it at first hand but later when i barely notice it it was horrible.
I had Tannoy reveal(passive) and this monitors go down from 60 Hz to nowhere........I don't know what happen down there cause I can't listen to I have twoquestions:

1) I'm using a hipass filter(20-30 Hz / -18 db McDsp Filter)) on the material I haven't Track myself and even some material I track myself but I know there could be some trouble down there.......Is this right? Am i loosing something doing this cut al 30 HZ????

2) I don't pretend to be a mastering engineer wiyh my equipment but i have no option......Is there a pair of nearfield monitors on the Us$1.000= range price that worth?? Is it better to change my monitors or Fixed my room ???

Anyway thank you......

good questions, indeed!
I wouldn't just remove all sub-30 Hz info willy-nilly, as A) you might remove some intended information, and B) most, if not all, HP filters affect well above the stated corner frequency. That is to say, the corner frequency is usually the point where some reference amount of cut is being had, often times 6db (depends on the filter design, etc, etc...) which means you're likely cutting higher than you think! (Particularly if you can't hear much below 60Hz...) which leads me to:
May I suggest getting a subwoofer to suppliment your monitors occasionally? Not that you would use it all the time, but just to screen for low-end trouble? Then when you do find nasties, you should be able to zero in only on the trouble spots, leaving the good 'boom' alone...
Just a thought,

Thank you cowtrax.......I know a subwoofers would help me....but iknow nothing about subwoofers....I mean how should I connect this with my actual speakers??? there are any special kind of subwoofers for my monitors??

Anyway this is a solution I find practical cause I know my monitors after working 2 years with'em so......

Any other suggestion????

Ok, for wath Brad say I think it's better first check the room before any idea of subs cause my room really should have problems(I don;t want to create more), then maybe I'll check Tannoy subs, just 1 more question:

Any suggested Book or Site or video on this Item(Acoustics)????

Thank you for your help,

Barbacoa - The generally accepted book for this is F. Alton Everest's book - here is a link to - (That's where I got my copy)

While you're waiting for your book, here is a site that can answer several of your questions.

Once you're there, click on Calculation Tools - if you have Microsoft Excel, their room mode calculator will tell you where to expect problems (provided you have a rectangular room - other shapes get more difficult to predict) The name of the file to download is MODESv2p.xls - The spreadsheet gives you quite a bit of information, some of which will probably make you glad you ordered Everest's book. Be prepared to spend some time on this - it's an incredibly deep subject, the more you learn about it the dumber you feel (at least that's how it continues to affect ME...)

Hope this helps... Steve

Another suggestion about the Tannoys:

They do have a pretty steep roll-off starting at about 95Hz so a sub might be a good idea, however they do respond down in the 30-40Hz range (albeit attenuated quite a bit). If you will listen carefully to some well recorded/mastered commercial CDs, you can hear the bottom end and see what it sounds like down there on the Reveals. Then, tweak your masters to give the same response. You might also want to run a Spectrum Analysis on some of those commercial tunes as well as yours & compare the results.

Good luck.

Hi, again, thank you all for your help, when I Post this I don;t expect I'll find so much answers.

I look for F. Alton Everest and I found 11 books...and the site that knightly give its very cool....I'm so happy with all this information that I can't believe..... .. ....what a great thing is Internet!!!!........

I can't wait to have this information.
