I've recorded a song for someone and I want to have it play in the messenger app for the person receiving the message, just as if I recorded it live. I have the file recorded in MP3, WAV, and FLAC, and have the capability to convert it to just about any format it needs to be. The important part is that it appears in the messenger app as if I recorded it live using the built-in recorder.
