[Tone controls and how they affect the EQ]

Not likely, as audio volume is logarithmic, not linear.

A graphic EQ setting to get similar to the simple tone controls would be to boost each band equally from your preferred starting frequency. A graphic EQ with more bands would have less peaking than one with less bands. A parametric EQ can more easily mimic a tone control when you use a shelf or pass filter.

Understood. Only I'm not sure by how much do I boost the bands if I'm incorrect about the percentage of the max decibels. What would 33% in my case translate to? Also don't you mean from the preferred starting frequency down for the bass knob and up from the treble knob? As in, 90Hz and below for bass and 10kHz and up for treble?

Also yes, I imagine a parametric EQ would definitely be better but unfortunately it's not always available. I plan to get a Fiio BTR5 for example that only has a graphic EQ to my knowledge.

Tone controls are a shelf type of control. The frequency you can select sets the start for the shelf boost, low pass for bass and high pass for treble. The standard is typically around 100Hz for bass and 10kHz for treble, but Poweramp lets you choose this.

If you are already using more precise equalization like a graphic or the even more advanced parametric EQ options, these additional tone controls are not really something I can suggest to be added to a saved in a curve for a headphone. They are mostly there to provide a quick way to sweeten a particular track.

So would I be correct in my assumption that the knob percentage represents a % of 15db (the maximum Andrew mentioned), boosted on the frequency set by the tone setting? Of course, I'm not mentioning the Q factor here since to my knowledge EQ APO only has a graphic EQ and a set Q but I'm fine with a little inconsistency. If I have the bass slider set to 33% in the Poweramp EQ app and the tone frequency is set to 90Hz (I haven't touched that up until now), I can raise the volume of the 90Hz band in EQ APO on Windows by 5db (33% of 15db) and have the same results, excluding the rest of the EQ settings I have? Or would I have to raise the neighboring bands as well by a fraction of what I'm setting the 90Hz band to?

 

Edit: I understand that you would not recommend using the tone controls. However, I set up those settings years ago when I first bought my current headphones. Back when I was tinkering with the settings it just sounded a lot better to me with the bass knob up 33% and treble up 35%. In a sense I'm trying to remove my reliance on them here and just translate the settings to a graphic EQ only so I can have the same sound everywhere I plug the headphones into.

So for example if I have the bass dial set to 50% and the tone bass frequency set to 90Hz, bands around 90Hz (depending on the Q-factor) would be boosted by 7.5db?

Hi,

I'm trying to replicate the EQ settings I set up on my phone to my PC through EQ APO. I can copy the bands and their respective db levels easily enough, however I don't really understand how Poweramp's tone controls work. I can see that the dial for both bass and treble goes from 0% to 100% and I can also see the affected frequencies and Q level by holding the Tone button. What I don't understand is how this translates into the band EQ, and furthermore how to replicate this in another EQ (EQ APO in this case). Can it even be replicated on an EQ without tone dials? Music in Poweramp (and Poweramp EQ for that matter) always sounded "richer" to me due to these tone dials and I'd give anything to be able to have the same settings on my PC and car bluetooth receiver.

Thank you :)
