Crossfeed: HF Attenuation doesn't go low enough

[DefineByte]

I'm trying to replicate the settings I use in foobar2000 as I find them very pleasing. Unfortunately the high-frequency attenuation setting only goes down to -6dB, which doesn't give the desired result (I'm after -4.5dB).

I've tried making do with what's available but I just can't get the sound field out of my head.

Would this count as a feature request or not? I'm unsure.

If I'm understand you, I can say that even if you have all settings exactly the same, they not will sounds the same, cause they are not the same Crossfeed.

But if the problem is just that you want the HF attenuation +1.5dB than the lowest degree (-6.0dB), you can try one of the next 2 ways:

1) You must compensate attenuating in -1.5dB both the Direct Gain and Cross Gain. Maybe this will works as the same as you increase HF from -6.0dB to -4.5dB.

2) Supposing that the Cross Gain affects the amount of HF adjust too, so you must compensate attenuating in -3.0dB both the Direct Gain and Cross Gain. Maybe it works as you increase +1.5dB on HF.

For example:

Suppose you have this settings on Foobar2000:

Direct Gain: -10
Cross gain: -10
HF Atten.: -4.5

Then you decrease all at same amount (-3.0dB), resulting:

Direct Gain: -13
Cross gain: -13
HF Atten.: -7.5

So, you finally increase 1.5dB to "HF Attenuation":

Direct Gain: -13
Cross gain: -13
HF Atten.: -6.0 You got the same result!

I'm not shure which method will works. You can try.

Sorry about my english.

Thanks a lot. I'll try that approach when I've got my iPod to hand.

edit: I got my settings at bit wrong before. I'm using the bs2b plugin  in foobar2000 and want to get as close as possible to it. It's settings are described as -5.5dB low-pass crossfeed and -2.5dB highboost (or low frequency attenuation). I'm not sure if these settings are even analogous to rockbox's. Sorry for the confusion.

I guess a greater parameter range wouldn't exactly hurt anyway. I'm going to do some work on the code in this area soon, and I'll have a look at it then.

That's great news. Thank you.

In the meantime I think I've got it closer. The sound seems to be coming from a bit too high up but I can live with that.
