During a lip synchronized performance, the system and method simulates signal level, proximity effect, and other parameters normally associated with a live performance. A proximity sensor attached in a fixed relationship with a microphone dynamically detects the distance between a microphone and the vocalist. A control data stream that includes dynamic distance information sensed by the proximity sensor is used to increase the signal level of the pre-recorded vocal track as the sensed distance between the microphone and vocalist decreases and decrease the signal level of the vocal track as the distance between the microphone and vocal track increases. ## Claims ### Claim 1 A system for enhancing a lip-synchronized performance of a performer utilizing a stage microphone, comprising: a proximity sensor secured in a fixed relationship with the stage microphone, the proximity sensor generating a dynamic distance data stream dynamically representing a distance between the proximity sensor and the performer;
