Air The Enlightenment

I downloaded a 1080p music video from Youtube. The video was great, H264 mp4, but the audio was horrible, 150kbps AAC by some google encoder. There was this hissing sound with the music or like a degraded static sound. Basta pakshet.  

Edit 11/6:

I found out that the problem was the audio filter of MPC-HC (150kbps AAC should be very nice so I tried with another player and it was all good). The volume boost made the sound bad. LOL my bad. I remember I tweaked it for a movie with weak audio. xD
