Question Why does my audio sound weird on YouTube?

[lyingfire]

I'm a producer and I upload my beats to YouTube, when im making them and export them they sound amazing. But when I upload them to YouTube, the hi hats sound loose and flat. But when i open the actual Wav file, they sound fine? I know it's fixable because any other channel that uploads beats, their hi hats sound fine.

(My beat I just uploaded, you can hear the hi hats (the constant "tiss") sound loose and flat)

What are you using to produce the content/music/video? Have you tried working with music files that are lackluster in quality to see if the audio is uploaded is not the issue and rather the audio output on your system/platform?
