I have a condition called diplacusis where one ear perceives the frequency or pitch of sounds differently than the other. Even if both earbuds are playing the same note, I will hear a different pitch in one of my ears. As a music lover this poses a slight annoyance that I would like to correct if possible. Of course any answers would be helpful for others with other motives as well.
I have looked, unsuccessfully, for software or drivers that can alter the frequency of every sound played by my PC in real time at all times, selectively for each stereo channel. Most recommendations are for real time left/right volume balance or post-production pitch correction audio software. Nothing is live and global like I need.
My PC's driver doesn't offer this option, as far as I can tell.
I use Windows 7 and Windows 10, software compatible with either of those would be appropriate. I might switch to Linux in the medium future so recommendations for Linux will eventually be helpful as well.
