hei. I had the idea to make a radioshow around audio letters.

audioletters come in all shapes, sizes and formats.

I collected a lot of tapes that also have audioletters on them. there are a lot of reel2reel things also and I m sure on the web there are even early digital audio letters.

so if you have some yourself, made some, or any useful links
let me know or post below:

very nice idea, I think I've only heard that one tape that you found here. I will keep an eye open, also I should make mp3 of the Talkgirl tape, unrelated.

There is a big stack of reel2reel tapes I have from Goodwill that I need to go through, hopefully there is some audio letters in there.
