Hacking the DROID Signature File for Characterization

by @beet_keeper

Identification of a format can be approached from many angles. Often a magic

number will be used at the beginning of a file. This may be strengthened by the addition of similarly consistent bytes at the end of a file or indeed any part of the bitstream inbetween. Using the sample file format we created last week the magic number to identify it is specified

I got into an almost-argument and I need advice and/or guidance from you dorks (affectionate).

Some doop on Reddit says he rips his CDs into flac files. I said the only thing that flacs increase in this regard is file size; not quality. He insists they sound better as flacs.

So, I ripped two CDs on my l33t h8xor Linux PC. 192kbps mp3s, and flacs. I genuinely could not tell the difference on any of my headphones, including the planar magnetic supernerd audiogasm cans. And I mean it: Zero difference.

Have I fallen into confirmation bias, or is there a real difference?

Do you think custom text file formats are a good idea? or should we just always use JSON/YAML/TOML?

File formats reveal a lot about the different meanings of an object.

@Etnaphele for those that shoot and spend time editing raw files, what do you do to your pictures?

I don't think I've touched a single raw #photo file in 2025 so far.
