George, you're asking for two things here:

1. EQ automatically changes to a certain EQ preset when in the car.

This is already done. Here's the FAQ entry on it.

The idea is that you'd have presets like this:

Preset 01: Flat
Preset 02: Bass boosted and treble rolloff
Preset 03: Bass boost only
Preset 04: Treble rolloff only
Preset 05: Deep cut in the midrange

(etc...)

Each one of those presets has a Home personality and a Car personality. Each of those presets has their own independent car and home settings. You don't have just one car-specific preset, you've got sixteen car-specific presets, and sixteen home-specific presets.

Trying to do "Preset 1=Car" is missing the point and misunderstanding the feature. The idea is to tune the EQ in its native environment and it changes automatically. Limiting yourself to only one car preset would be a pain, and would waste the flexibility of having all those presets.


2. Per-song tone correction.

This one isn't done in the default software. But I always figured that setting up an entire EQ curve per-song would be a pain in the ass. I had a better idea a long time ago, discussed it here on the BBS. It would be a lot easier to implement, and a lot easier to maintain. It involved using the Bass Boost and Treble Boost code in Hijack. Who was it that originally created that code, was that Genixia?

See, setting an entire eq curve just for one particular album is a problem because that's too much detail to go into per-song. All you REALLY need to do is boost or cut the bass or treble on a per-song basis. While letting the EQ's to be your baseline.

Anyway, imagine that a given track has, in the comment field, the text "HIJACKBASS+1" and/or "HIJACKTREBLE-4". Or something like that. Then Hijack could check the comment field (it comes in the Notify text doesn't it?) each time a track plays. If the text isn't there, then it doesn't change the amount of bass/treble boost.

Note that this would be additive, per track, compared to the bass and treble boost settings already there in hijack.
