We have invented devices to record what we can see, and devices to record what we can hear.
Why haven’t we invented something to record what we can smell?
How would this work if we did?
\[When I am travelling I really wish I could record the way things smell, because smell is so strongly evocative of memories and sensations.\]

So we can record sound as it’s just vibrations, play those same vibrations back and you reproduce the same sound. we can record video in a variety of methods all of witch involve it hitting something light sensitive and either recording it or altering what it hits to capture those reflected photons. When it comes to scent it relies on the specific partials entering your nose and interacting, to record and reproduce a smell would require sorting out the particles we are not interested in, then figuring out the chemical/molecular/elemental make up of what remains, then somehow fabricating and reproducing said particles, and keep in mind the wide range of things that cause smell from organic proteins, metals, chemicals compounds, and everything else and you start to see the trouble of replicating all of that.
