Would I be correct in assuming all the eq work should be done before any effects,such as reverb/delay are laid on? Or is it usual to need more eq tweaks after applying effects?
I would answer this with a "yes, but..."
Within a DAW there are basically 2 ways to apply an effect such a reverb and delay
1 - An "INSERT" effect
2 - A "SEND" or "FX BUS"
The second option is the
correct more accepted way of approaching fx such as reverb and delay
This involves setting up BUSSES and SENDS, which can get a little confusing so I would actually say to not worry about this until you want to take your mixing to the next level (which at your rate won't be long!)
The main advantage of this approach is that you send your tracks to a common fx (such as reverb) which serves a number of purposes:
1 - sharing the same reverb across all tracks puts everything in the same space - which helps glue things together
2 - as you are only loading one effect on the fx bus you can send all tracks to this bus, which saves on CPU
3 - you can process the actual effect - eg applying EQ to the FX BUS - such as adding a High Pass Filter to a reverb to stop the reverb making the mix muddy (eg the "Abbey Road" techniques discussed here:
http://www.songwriterforum.co.uk/index.php?topic=11926.0 From your description I am assuming that you are using an "INSERT" effect, where you are putting the effect on the track you want to process - so if you have 4 tracks that you want to add reverb to, you are adding 4 separate reverbs (or the same reverb 4 times)
This has a similar end result but this approach uses more CPU resources
If you are using this approach (which is fine for now) then I would say you are correct to do the EQ before the reverb - however, there are no rules so if it sounds better doing after - do it!
Am I right High pass filter low pass filter sounds like it's just preset EQ? I know in audacity you can drag the EQ to cut out high/low frequency so is this the same thing?
A High Pass Filter is generally a function within the EQ that takes out the low frequencies as you drag it across the frequencies from low to high - if you drag it all the way to the high frequencies you will here just the very high frequencies
When I get around to creating the videos it will be really easy to demonstrate
