Extract AAC audio properties using Python?

What's the easiest Python library to use to extract properties from an AAC audio file (.m4a)?

Specifically, I'd like to extract the following properties:

• Sa开发者_高级运维mple rate
• Channel count (mono or stereo)
• Length (in seconds)

Try the AudioFile class in Audio Tools.

Try using the command exiftool. Of course, if you're using linux. This command shows all the properties of audio files, video and pictures. Exiftool installed, simply use the command:

exiftoll your_file_name.extension

eg exiftoll music.mp3
