The Best YouTube Comment EverThis was following a lovely video of a cover of Strawberry Fields Forever by La Santa Cecilia:
Animation and Beatles cover are cool. The vocals and accompanying instrumentation are really distorted in spots. I'm monitoring in a studio. The optical S/PDIF out from my tower goes directly an external AD converter to calibrated active speakers. Not having the same effect from other videos at hotter levels. Even with the volume down at youtube's interface I'm experiencing the same effect. You may have a corrupt file or somehow over compensated with a peak limiter on layback. It's a shame.
