Narrative:

At approximately XA10 am I was PIC of atx X and was instructed by the ground controller to taxi via taxiway T, runway 22, and to hold short of runway 12R. Upon reaching the intersection of taxiway T and runway 22, the controller called and said 'atx X stop.' I stopped and acknowledged. The aircraft stopped short of runway 22 and 5- 10 seconds later a departure aircraft passed in front of us while we held short. Afterwards I was instructed to call the tower by phone and did. I spoke to a supervisor who informed me that I had misunderstood the original taxi instruction. He informed me that he had heard the controller tell me to taxi via taxiway T and hold short runway 22. I apologized and thanked him during our discussion of what had happened. I did not talk to the controller who actually instructed me. I plan to get a copy of ground control tape to verify if I was at fault.
