I use this site for that:

I have streamed the audio from my mac mini, but I suppose it would work with any phone.
Yeah, I can confirm it works on a phone. I actually built a native iOS app that allows you to browse the asciiexpress games and disks. The advantages of this over the mobile web versions of asciiexpress.net are:
- Easier browsing, I'll be adding a search / filter option
- Game art (when available)
- Automatic control of volume (making sure your device volume is set to max when playing disk audio)
And a future feature I'm hoping to be able to tackle - on device generation of the audio. So rather than having to stream the (relatively) large audio files from a remote server, I could, in theory, take the very small disk image, and convert it, realtime, into the audio needed for cassette input. Still trying to see if this will be possible, given my lack of knowledge of embedding C code into a Swift iOS app. Theoretically, this is possible, but the question is whether it's possible with my skillset / level of knowledge.
And, there's still the question of whether Apple would even allow an app like this in their App Store... More to come, hopefully.
