What is compression and why do you use it? What exactly is a limiter and where is it usefull. I understand some of these to a degree but do not know what situations to use them in. EQ... well there again, I know what EQ is but not how/why/where to use it [:)]
Well basically you may imagine a compressor is something to even out the dynamic range of a certain track, which it makes the loud bits sound softer and the soft bits sound louder. You wouldn't want this overdone with orchestral instruments though coz classical/orchestral music DOES have big dynamic range, unlike pop/rock or vocal music, which usually goes for a more static volume. Compression can kill an orchestral/classical track VERY EASILY, beware hehe!
Limiter is similar to a compressor except it ONLY "limits" how loud the track is. Could be a great tool when you are recording live music , especially close mic'ing that you wouldn't want that singer suddenly goes berserk and clip every note! [:D]
Beat's tutorials explains EQ very well I think. It's just a tool to change the timbre of an instrument. And the best application of it is not to use it at all! [:D] At least in the beginning stage hehe. But simple editing like cutting off high and low frequencies (as mentioned in the tutorials) will help a lot for the placement of the instruments, coz, imagine you are hearing a violin like 20 metres away from you, that definitely won't sound as "bright" as when it's just 1 metre away from you, therefore why a cut in high frequencies (using EQ) will help. Same goes for bass instruments as well, for the low frequencies.
And IMHO, if you find certain notes in a track sound too loud, I would rather use EQ to "tune" down it than using compressor. At least for orchestral instruments coz it's more natural. Or just simply run a limiter and set to, say, loudest volume = -8dB.
You could load a pop/rock track and an orchestral track in your audio editor, and check how the two WAV's look like and you might understand what I mean!
These are just very general remarks, please don't take it as the ultimate solutions! hehe.
