Abstract
A system and method for optimizing digital audio playback is disclosed. The system and method can prevent playback of a digital audio file in an enhanced mode if the digital audio file does not meet a predetermined criterion, such as a particular bit rate. One example of an enhanced mode is a simulated multi-channel surround sound mode.
