What can't u do with the 4-band parametric? I think recording and mastering studios typically use a 4 or 5 band PEQ but I haven't kept up with the DAW space for a while now so ...
You may be aware of Jaako Pasanen's AutoEQ project for automated equalization of headphones based on measurements available on the net or using one's own measurements. As he says in the readme:
Quote:Keep in mind that parametric eq accuracy depends on the number of filters available. Usually 10 filters produce very good results but as little as 5 can be good enough.
Now four PEQs are certainly better than nothing but in this case more is definitely better. I have a MiniDSP Ears headphone measuring rig and a MinDSP 2x4HD that can use 10 PEQs on both the input and output and I assure you a 10 band EQ can sound a lot better than a 4 band EQ, especially on 'difficult' headphones. On some 'phones I could use even more than 10 bands.
So why not just use the MiniDSP you may ask? Well, I am! But I would prefer to use a different DAC, plus the 2x4HD isn't the prettiest device to have sitting on my desk. Also the 2x4HD has only 4 preset slots and changing presets is a bit clunky. So being able to do the full EQ in software on the Pi (preferably in Mooode) would be most welcome.
