Are there any programs or tricks to converting any file, say a text file or a picture, into a music file like MP3 or WMA? To be clear, I'm not looking for text-to-speech, I mean literally use the bytes in a file as music. I searched for it on Google but all I found was text-to-speech software.
It's possible to do, but I've not seen any programs to do so.
At the most basic level, it's possible to convert the 0s and 1s into two sounds with different frequencies and play them in sequence. Beyond that, one can perform an inverse FFT with the bits in the bytes representing different frequencies, or one can even do what modems do and modulate the amplitude and phase of a sine wave in order to encode the data as sound.
