  * Description: AI voice conversation sample wrapper
  * Author: Media Software Group
  * Create: 2023-07-06
+ * 
+ * Silence Audio Configuration:
+ *   - By default, uses 1100-byte silence audio data (with ID3 tags)
+ *   - To use 288-byte version (pure MP3 frames), define USE_SILENCE_AUDIO_288
+ *   - Both versions use the same variable name: silence_audio
+ *   - Usage in code:
+ *     * silence_audio: array pointer to selected audio data
+ *     * SILENCE_AUDIO_SIZE: macro for size of selected audio data
+ *     * silence_audio_size: const variable for size (same as SILENCE_AUDIO_SIZE)
