if you could pick a standard format for a purpose what would it be and why?
e.g. flac for lossless audio because…
(yes you can add new categories)
summary:
- photos .jxl
- open domain image data .exr
- videos .av1
- lossless audio .flac
- lossy audio .opus
- subtitles srt/ass
- fonts .otf
- container mkv (doesnt contain .jxl)
- plain text utf-8 (many also say markup but disagree on the implementation)
- documents .odt
- archive files (this one is causing a bloodbath so i picked randomly) .tar.zst
- configuration files toml
- typesetting typst
- interchange format .ora
- models .gltf / .glb
- daw session files .dawproject
- otdr measurement results .xml
because if you use a 40 kHz signal to “draw” a 10 kHz wave, the wave will have only four “pixels”, so all the high frequencies have very low fidelity
As long as the audio frequency is less than half the sample rate, it is a mathematical function with only one (exact) wave that is able to fit all 4 points, so it is perfectly reconstructed. This video provides a great visualization of it https://www.youtube.com/watch?v=cIQ9IXSUzuM
