Oh, I’ll check that out! Part of why I like the Naturespace recordings so much is that many are straight field recordings. There used to be an iOS ap called Ambiance that had the ability to record and share one’s own soundscapes. there were thousands of files available to download through the app and it was maintained until Apple dropped the 32-bit downloads from the AppStore. I got the best ones I could and have it still on a handful of older devices. Got to crack it open at some time and excise the sound files as it’s only a matter of time before the devices get spicy pillows and fail.
