Is there a way to snapshot WAV audio files?

Package development

Hello everyone,

I'm trying to test a function that generates a .wav audio file with snapshot testing from testthat. I know that there is whole file snapshotting that has "initial support for images (.png , .jpg , .svg ), data frames (.csv ), and text files (.R , .txt , .json , ...)".

Is there any support for audio files in the form of .wav or .mp3?

I don't think that there is direct support for audio files. E.g. there is no easy way to compare a changed audio snapshot to the original snapshot.

Maybe comparing the output byte by byte would work for you, or you could calculate the hash of the file and save that.
