 ### Performance Considerations
-- Static compilation of audio data eliminates file I/O
-- Lazy loading prevents unnecessary memory usage
-- Efficient hashmap-based dictionary lookups
+- Audio data is compiled directly into the binary, eliminating runtime file I/O
+- Efficient bincode serialization for compact data storage
+- High-performance hashmap-based dictionary lookups
 - Optimized crossfading algorithm for smooth transitions
