I'm hitting something like this. It's awful. Things I've noticed: * It only affects one of my computers * On this computer, it only affects playback in Pandora website, in Chrome * Using Chrome to playback the exact audio file that Pandora.com's player downloads sounds fine * Using Pandora.com's player in Edge sounds 'fine' * Using Pandora.com's player, on Chrome, on this one specific computer, produces a spectrogram like this: Frequencies above 9.8khz are being filtered somehow. Then, when on the onset of high energy in the upper bands, *250ms later* it allows a few of those frequencies to screech through. I'm pretty convinced it's some sort of driver-level issue on the specific computer... although I just started a 'free premium trial' to be able to replay the same song across multiple situations... and uh, the issue significantly reduced in Pandora's player during the premium trial. Here's some snippets from the same song: Chrome, Non-Premium: Chrome, Premium-Trial: We're getting a lot more over 9.8khz when we are in Premium Trial mode. But take a look at playing a song in Edge (not same song, couldn't get to it in number of free skips) Edge gets *much better* audio quality. I don't know what the conclusion is. It doesn't seem to affect all computers, but the ones that it does affect seem to be Pandora Player's fault, and it improves significantly if you have Premium. But to really get audio above 9.8khz, switch to Edge.
