Sound equalization plugin [$25]

[Natrox]

My Vita 1000 speakers are too heavy on lows, I'd like to tweak the sound output to reduce lows and empathize highs.
I'm not actually sure if it's possible, but I will be working on it as well.

I'm new to Vita homebrew development. I have worked with the official development SDK in college, which disqualifies me from making major contributions to the homebrew SDK (legally speaking). I will also be working on this plugin, if it is possible without SDK modification.

My educated guess (without understanding of the SDK) would be that something like this could be achieved by hooking into the audio output functions - at some entry point where buffers are filled or pushed to the output hardware. However, that's an assumption and I might be talking out of my ass; hence the bounty.

Specs of deliverable:

• Plugin needs to have 8-bands at least.
• Plugin needs a front-end, preferably a GUI app - but for starters a config file will be sufficient.
• The solution needs to impose no more than one 'frame' (16~33ms) of latency.
• Plugin should be system-wide, meaning it should work in the LiveArea, games and Adrenaline.
• Equalization of headphones output is optional.

If I manage to complete the bounty myself, I will put $25 on a project of my choosing.
