Hardware Tweaking an N3DS XL's audio to pitch it down half a semitone?

[Melodybun]

Hello,

To summarize, my perfect(?) pitch has drifted these last two years, and I hear everything pitched up half a semitone, so I like to adjust my electronics' audio accordingly to compensate. I asked about tweaking my N3DS XL's pitch once before (and then made a post about it on Luma3DS' github), and I was told that I'm screwed software-wise; that my only hope might be some hardware tweaks.

Since all 3DS softwares' audio is apparently coded into the software itself, the only other things I've had to go off of are very tentative ideas that were thrown around in my original github post here. Am I screwed? Have any new developments come out since then?

Thanks,
Melody

I thought that doesn't happen until a person is in their 50's. Wouldn't it be easier to retrain yourself instead of adjusting all of your electronics? And how does one adjust pitch on something like a television? Perhaps you connect your PC to your tv and use something like Equalizer APO to pitch shift the audio?

Wait, can you retrain your ears like that? Also yeah, it's been like this for two years now sadly -- screwy genetics, I'm sure. May also be partially attributed to my diplacusis (my ears hear slightly different pitches). And TV-wise, I might just be screwed, sadly

As a quick update, I posted an "issue" on Luma3DS' github page, and I have had a little back and forth with the head dev, a TuxSH. He mentioned biquad filters, and hypothesized that one or two of them could adjust my 3DS' audio, potentially without even having to make changes to Luma3DS itself!

However, I'm not sure how to actually *apply* said biquad filters. He linked me to a biquad calculator and asked if "this was the case for me," but I'm not sure what I'm actually supposed to do with the calculator, or how to answer that question. Any advice from someone who knows a thing or two about biquad filters would be greatly appreciated!
