Ah, thank you! See, it didn't even occur to me to just intercept the audio in transit. That's really helpful, I will try this, thank you very much :)

So I’ve reverse-engineered the naturespace Android APK and the files it downloads are definitely encrypted. They’re zip files (named as .nzp) that are XOR obfuscated with a rotating key every X amount of bytes. I haven’t quite worked out how the key rotates itself but I’m close. If I get it working I’ll put the details here and I can give you a Python script to grab whatever sounds you need.
thanks for using Leebra!

If the content is being downloaded then you could do the following:
Setup a proxy like Fiddler2 on a PC on the same network your phone is connected to. You’ll need to configure Fiddler2 to decrypt HTTPS and then access the proxy certificate on your iPhone and add it as a trusted certificate. You’ll need to Google how to do this with Fiddler2 but it’s not hard
Configure your iPhone to connect through the Fiddler2 proxy by modifying your WiFi settings. If your PC is allowing connections to the Fiddler2 proxy port (e.g. 8888) and you’re trusted the cert on your iPhone, then connecting to websites in safari should be working
Open the naturespace app on your iPhone and delete the sounds you’re interested in. ONLY do this if you’re sure you can still re-download them. If not, this whole approach won’t work so just stop here.
Download the sounds again
You should then be able to see the web requests that were made to download the sounds in Fiddler2 on your PC. As long as there’s no fancy encryption, you should be able to just save the content out of Fiddler2.
