I am currently being threatened by my former employer (they are "compelled [to] take action against [me]") for the way I am running ANN, and how this allegedly violates my employment contract with them ("interfere _in any manner_ with any business relationship between the Company and any of its customers or business partners"). This might entail drastic changes to the relative freedom of speech ANN has always allowed its visitors, or ANN might close down altogether. Updated 10:00 CET.

Legal threats? : Comment 1037 of 1057 | ANN.lu |

Who needs a 33-bit processor? You can do 64-bit sound in Windows with DirectX plugins (like Ozone) on a 32 bit Pentium.

Rounding errors can't exceed the Least Significant Digit in error. it's mathematically impossible. Take the high and the low range of error and do any calculation on them, and they can't effect the Significant Digits.
Pick any value for a few 24 bit integers (with rounding error) and a few 32 bit integers (with rounding error) and downsample to 16 for both sets and compare. If the 16 bit number is the same, then your sampling range is within the significant range and all rounding is happenning outside of the set.

It doesn't require a 64 bit CPU to do 64 bit sound processing, any more than it requires a 24 bit CPU to display 24 bit color. Windows with an Ozone DirectX plugin handles it fine.

Of course not, but at no time was it even considered that, The difference between the video, and the audio, is that your digital audio won't be digital when it's listened to (but the video will), and will in most cases be played through a 16/24 bit d/a converter before it hits the speaker, and if you take the Significant Digits into consideration to find the largest error that would change a value being passed that would change a value in the 24 bit stream, it would never mathematically be smaller than the resolution of a 25 bit stream, no matter how severe the rounding error in the sample.
Anyway, that's all moot anyway, as audio technology (distrobutionwise) is actually going back to the damn stone age as people are regrettably satisfied with lossy compression, and it looks like these idiots are going to actually start selling most music in it's lossily compressed form in the future when they can. :( |
