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 1043 of 1057 | ANN.lu |
Posted by minator on 10-Apr-2004 22:46 GMT | In reply to Comment 1039 (Martin Blom): >24 bits is 144 dB; good luck finding a D/A converter with this SNR.
>And good luck even trying to hearing anywhere near this dynamic range ...
I 100% agree.
I can remember being told by an electronics teacher the even 16 bit was overkill because the converters are non-linear - that is the voltage error at the 16th bit is likely to be far bigger than any error in the signal you are feeding it.
However, even if you had a super good converter (probably several hundred $$$) how many people have the type of sound system that it'll make a difference on?
You'll only use 64 bit for audio processing to prevent overflow, you'll never hear anything near that resolution, so it'll make no difference error accumulation or not.
The best audio gear is analogue, and it's good because it *adds* distortion.
32 bits is 192 dB. Assuming rounding errors account for one LSB error/calculation (which indicates a flawed algorithm, but let's assume), and your speakers output sound at the threshold of pain for full swing data, it would still take more than 4000 calculations before you even have a theoretical chance of being able to hear it. That IS "plenty". |
