In general throw money at the problem first, resort to code last
Digital: where the audio is received in a digital format and converted by the listener.
Vinyl: where the audio is etched into a flat disc, inscribed in a modulated spiral groove.
Analog Radio: where a carrier signal has its frequency or amplitude modulated by the input signal and has its power increased to transmission levels.
Digital includes, CD-audio (red-book), lossless compressed audio, lossy compressed audio, satellite radio, "HD radio", DVD-audio, SA-CD, or anything where the digital to analog converter is at the listener's end.
Vinyl includes...well mono/stereo/quadrophonic phonograph records.
and Analog radio pretty much exclusively includes FM radio.
I have omitted analog magnetic tape since we don't really use audio cassettes or 8-tracks any more.
Also note: even though the radio station may receive a digital file, a mastering engineer may have been asked to tailor that file for being broadcast over FM which could lead to different treatment of the frequency balance, stereo field, and whatever else the engineer felt necessary.
