Then the rest seems to ‘flat line’ the rest of the way out.<–is THAT the way its supposed to be done using this method? The reason why I'm asking is because when I made mine, for some reason I thought I was supposed to cut at both ends ( highs and lows ) … I know you're probably gonna tell me what ever sounds best is the right way, but I'm just asking for reference sake so I have a more solid platform knowledge wise to start from, and from there I can attempt to 'fine tune' things. I am still learning getting my mixes down and feel like I need to test in the car before releasing anything, every time. I’m toying around with a new project and I’m trying to implement everything I’ve been learning from you ( as well as other people you’ve suggested ) and sometimes I get a bit overwhelmed and tend to confuse things up in my head lol! Well, when I returned to this post in particular, I noticed that the pictures of the filters on your site and the others have basically one curve going down doing the cutting off. Does anyone have/know where I can find some Parametric EQ 2 presets that simulate a car stereo, phone speaker, etc. Anyhow, I have a question about these high pass filters.
