+**Automatic Handling**: The app automatically handles long recordings:
+- **MP3 Conversion**: All recordings are converted to MP3 (64kbps) for 10x compression
+- **Chunking**: Files ≥18 MB are automatically split into 10-minute segments
+- **Processing**: Each segment is transcribed separately and merged with timestamps
+
+**Example**: A 2-hour meeting:
+1. Records as WAV (~120 MB)
+2. Converts to MP3 (~12 MB) 
+3. Stays under limit → No chunking needed!
+
+**Very long meetings** (e.g., all-day workshops):
+- Automatically chunks into segments
+- Shows progress: "Processing chunk 1/15..."
+- Merges all transcriptions seamlessly
