He founded xiph.org, created the Ogg container, and helped write Vorbis and Daala.

he's tired of explaining to people(about 24/192 sound) that..



With use of shaped dither, which moves quantization noise energy into frequencies where it's harder to hear, the effective dynamic range of 16 bit audio reaches 120dB in practice [13], more than fifteen times deeper than the 96dB claim.


120dB is greater than the difference between a mosquito somewhere in the same room and a jackhammer a foot away.... or the difference between a deserted 'soundproof' room and a sound loud enough to cause hearing damage in seconds.


16 bits is enough to store all we can hear, and will be enough forever.

Some people buy $500 wooden knobs to make their volume pots sound better. (or was that a hoax? i can't tell anymore)


Some people buy small pyramids to elevate their cables off the floor, some people buy mats to put onto your CDs before putting the CD in a player (http://dagogo.com/millenniums-m-cd-mat-carbon-cd-damper-revi...), some people buy $1000+/meter digital interconnect cables (http://www.theabsolutesound.com/articles/transparent-referen...), some people buy $7200 power cords (http://www.theabsolutesound.com/articles/crystal-cable-absol...) and $350/m HDMI cables (http://www.theabsolutesound.com/articles/nordost-releases-fi...).


Self-styled audiophiles are, by and large, idiots with way too much money plagued by magical thinking. Developer bullshit has nothing on them.



and the best comment..



Oh sure, your rips may be perfect at the bit level, but how do you know that they're free of sub-bit quantization that isn't detectable by electronic circuits but can be heard by the human ear?


This sub-bit jitter and interference can travel along with a digital file and sneak right past your ordinary bit-level error detection and correction, no matter how lossless you make it. That's because these errors aren't visible in the bits. They occur at a deeper and more subtle level, in between the bits.


Even if you prove mathematically that two files contain the exact same bits, you can't prove that the human ear won't hear any difference, can you?
