Audio Modem for data over sound

[VAG]

I am building an audio checking script on PC which requires me to identify the audio on another platform. eg. TV or Boombox. So I need to encode some metadata into the audio track on TV or  Boombox for my script to identify the current playback audio correctly.

I was thinking of encrypting the metadata into the beginning of audio track using [Audio Modem] method. I found a few api like followings:

I would like t know is there any UDF already exists which uses Audio Modem as example?
