You can use ffprobe which has an option to output JSON format.

Take a look at this example:

ffprobe -v quiet -print_format json -show_format Ramp\ -\ Apathy.mp3

Which produces the follwing output:

{
    "format": {
        "filename": "Ramp - Apathy.mp3",
        "nb_streams": 2,
        "format_name": "mp3",
        "format_long_name": "MP2/3 (MPEG audio layer 2/3)",
        "start_time": "0.000000",
        "duration": "203.638856",
        "size": "4072777",
        "bit_rate": "159999",
        "tags": {
            "title": "Apathy",
            "artist": "Ramp",
            "album": "Evolution Devolution Revolution",
            "date": "1999",
            "genre": "Metal"
        }
    }
}

I'm using ffprobe version 1.0.7.
