I just posted this on hydrogen to ask their expert opinions about this thread... here it is... http://www.hydrogenaudio.org/forums/...howtopic=53707

And if it LOOKS the same it ALWAYS SOUNDS the same, vice versa it doesnt. |

You haven't tested this hypothesis, yet you just keep asserting it as if it were fact. Moreover, you haven't demonstrated at all that these graphs have anything to do with predicting or observing how these codecs perform with respect to music as opposed to pure tones. When donunus posted on Hydrogen Audio about this method of evaluating codecs, one of the Hydrogen Audio members posted this graph to make the point that pictures do not always tell the story: You should read the Hydrogen Audio thread, particularly the part about why the Blade-encoded graphs look "almost perfect." |
