How to build a digital FM receiver for recording audio in MP3 format? Preferably directly to Android phone? Answered
I have this thing:
Which I use during lectures so that I could properly hear the lecturer, and it works very very well - I can hear him perfectly when he "wears" it so that microphones are close to him.
I also have the FM receiver part which works in conjunction with a hearing aid - no issues.
However, I also would like to RECORD everything he says, a technician told me the FM frequency used by the Phonak system is Channel 16 frequency: 174.1200 MHz (174120.0 HZ)
I tried a few Google searches, but I did not come up with any leads or ideas, how to record this transmission - best would be to an MP3 file or something, I could store on Evernote or something along with the lecture notes I take.
I should also point out, I have an Arduino Uno at my disposal (with Prototyping shield).
I am open for any and all ideas, and suggestions how to get this done.
I might require some help as electronics is unfortunately not my strong suite (software development is, however).
