Nothing worst than listening to hard panned early blue note jazz albums with headphones. It can give you a head ache. I would love to see a stereo crossfeed implementation of some sort added to the plex mobile app. And gapless playback while you’re are at it! Please! ---

I use it daily on my Laptop and Xbox Ones. I have it cranked up in the lounge when I’m doing weights and I would really love to have crossfade, it is generally the one thing that will make or break a music app for me lol except in this instance I love plex too much for all of the rest of my media needs. Please help me get this feature implemented smiley ---

^This. [Here is a brief explanation on crossfeed from Meier Audio.](http://www.meier-audio.homepage.t-online.de/crossfeed.html) It operates on the simple principle that you hear a little bit of the left channel in your right ear and vice versa when listening through speakers. In practice, it mixes in a very faint, slightly delayed, equalized version of the opposite channel to the left and right channels, respectively. But different from a head-related transfer function (HRTF) which can compress the dynamic range of the source material and degrade sound quality with unnatural tonal resonances, crossfeed is much less destructive to source audio. It does not apply any reverb or other effects that can disturb the fragile nature of audio, but its minimalistic approach creates a contiguous soundfield inside your head. The “Meier” style of crossfeed is already implemented in MPC-HC and Foobar2000 in open source code, which is publicly available and very simple to implement in code. Here is open source code you can reference for implementation.

Extended this request to “mobile apps” instead of just for the iOS app. ---
