1. An apparatus, comprising:
- a radio tuner that receives radio frequency signals and converts the signals to audio output;
an audio comparator that compares audio output from the radio tuner with audio output from an automobile radio and tunes the radio tuner until the audio output of the radio tuner is synchronized with the audio output of the automobile radio; and
an audio storage device activatable by the audio comparator to record the audio output of the radio tuner, wherein the comparing includes;
sampling the audio output from the radio tuner;
sampling the audio output from the automobile radio;
accumulating resultants of the sampling; and
identifying a synchronization based on a threshold associated with the resultants.
