Someone posted about their measurements result on my prank.....I mean my experiment I shared again recently. Here's what he said.
He said he actually measured the signal and found extra microwave RF smearing the analog sections of the dac. What do you guys think about this?
while I did not even read the article, this is the same discussion why flac vs wav can sound different even though technically they contain the same waveform
suppose you have a wav file:
- one on a normal filesystem
- one on a compressed filesystem
- one on a btrfs filesystem with bit rot detection via checksums
- one on an encrypted filesystem (eg truecrypt, veracrypt)
accessing the same wav file on these different filesystems will cause a completely different cpu load pattern
the encrypted filesystem will cause the highest load, while the normal filesystem will cause the lowest load
all cpu's radiate microwave, which is visible as RF in the PC case, and also partially transmitted via USB to a USB DAC
while the bits are technically bitperfect and a filesystem will not normally flip bits, the extra microwave RF will smear the analog sections of the dac
this was confirmed by dac designers
we did these measurements and the load patterns of wav vs flac are completely different
you may have the false belief that all async dacs solve these issues as they are master of the clock and the data is bitperfect, but it simply does not work like the ideal world.
