Abstract
Apparatus, system and method for reading ancillary code embedded into digital audio, where a processing device executes a decoder application that includes a decoder application interface that is communicatively coupled to a media player application within one or more frameworks of the processing device. As digital audio is received and sampled, the decoder application is configured to transform the digital audio from a time domain to a frequency domain and to process frequency characteristics to determine the presence of ancillary audio codes.
