O M F G ! ! ! ! ! !
i didn't type a title, and clicked Submit and it means your message gets wiped. How ANNOYING :mad:
ok i'll just recap
I've been doing some research on compression and filtering. But one thing is beyond me. When people say like, "yea i had my bass at 60(KHz?) and my wotsit at 150, what are they using to detect it?
Is this what spectrum analysers are for, and what kind of programs can be used as spectrum analysers? |

When people say their kick is at XXXXhz, they're usually talking about what note that element is in and are simply using their ears.
ie. Say if you had a kick that peaks at 261hz, the kick would be at middle C.

Ohhh right. I just didn't think about that. I play guitar and i know about frequencies in that respect. Like A is 440, and the octave would then be 880. I understand that now.
Thanks for the links, greatly appreciated. :) |

i use a spectrum analyser. although you can roughly do it based on piano keys and their corresponding frequency, i tend to pitch samples up and down alot and use samples where it is difficult to tell the key (percussive samples mainly).
i use a spectrum analyser for this. there are a number of free ones out there - voxengo SPAN and elemental audio system's Inspector.
a spectrum analyser is just a real time graph. with the level in dB on the y axis. and the frequency in Hz on the x axis. playing a sound through it tells you the frequency range it occupies and in what specific frequency range it is loudest (thus has the most dominance).
i consider it one of the essential tools i have and its probably one which i use most consistantly with EQs, filters and compressors. |

| thanks derivative, that helped alot. |

| get used to looking at various instruments through a spectrum analyser - you will start to see a few patterns emerging ;) for example most deep kick drums will show a massive peak/hump around 55 to 120 hz then tail off. alot of vocals look like a load of spikes starting at 150 and going to about 7 or 8000 hz then dropping off fairly sharply. the idea is that each instrument takes up a physical space in your mix. and if you want to get the cleanest kind of sound you want to ensure that each instrument doesnt overlap so much. this is where spectrum analysers are really useful. |

| Thats just the tip i needed to hear. The more songs i make, the cleaner they are getting, and thats what i'm going for with this next song, hence the research into compression etc. So yea i'll definatly be encorporating the Spec. Analyser in the next song. Thx again |

Just read The Principles of Sound. Very interesting and well explained. A+
----------------------------------------------------------------
Also just read 2 other parts, Understanding Trance Music and Understanding Basic Trance Structure. I'm sure this will help alot of people out a great deal. Gonna read the parts about EQing tommorow. Bed time now :o yawn |
