+        - Converts MP3 to FLAC format
+        - Ensures 16-bit depth (CD quality)
+        - Maintains original sample rate
+        - Lossless compression for FLAC output
+        
+        **Technical details:**
+        - Uses pydub for audio processing
+        - FLAC files use 16-bit PCM encoding
+        - Original channels (mono/stereo) are preserved
+        
+        **Note:** This is a format conversion, not quality enhancement.
