The optional `backends` parameter can be a list of audio file classes to try opening the file with. If it is not provided, `audio_open` tries all available backends. If you call this function many times, you can avoid the cost of checking for available backends every time by calling `available_backends` once and passing the result to each `audio_open` call. If all backends fail to read the file, a NoBackendError exception is raised.
