+# Audio File Display Name Fix - Complete
+
+## Problem Solved
+User wanted audio files to show proper "Artist - Title.mp3" names when sent to Telegram, but without changing the saved filename on disk.
+
+## Solution Implemented
+1. **Reverted file storage**: Files are saved with original format `${videoId}_${title}.mp3` 
+2. **Custom display filename**: Added logic to generate custom filename only for Telegram display
+3. **Modified sendAudioFileInternal()**: Now accepts both URLs and file paths, generates custom filename for display
+
+## Key Changes in src/bot.ts
+- Function now detects if input is URL or file path
+- Extracts local file path from URL when needed  
+- Generates custom display filename: `${performer} - ${title}.mp3`
+- Uses file options parameter to set custom filename in Telegram
+- Maintains backward compatibility with both URL and file path inputs
+
+## Technical Details
+- Uses node-telegram-bot-api file options: `{ filename: customFilename, contentType: 'audio/mpeg' }`
+- Sanitizes performer and title for safe filename (removes special chars, limits length)
+- Fallback: sends as document if audio fails
+- Error handling: sends text message with link if all methods fail
+
+## Result
+- Files stored on disk: `123456_song_title.mp3` (unchanged)
+- Files displayed in Telegram: `Artist Name - Song Title.mp3` 
+- No more "🎵 ..." caption text
\ No newline at end of file
