# Audio File Naming and Caption Improvements

## Changes Made

### 1. Frontend (public/script.ts)
- Added `performer` field to `/api/convert` request
- Now sends artist name along with title and other metadata

### 2. Backend (src/server.ts) 
- Updated `/api/convert` endpoint to accept `performer` parameter
- Modified filename generation to include artist name:
  - Format: `{artist} - {title}.mp3` (when artist available)
  - Fallback: `{title}.mp3` (when no artist)
  - Limited artist name to 20 chars, title to 30 chars for safe filenames

### 3. Bot (src/bot.ts)
- Removed "🎵 ..." text from audio message captions
- Changed `caption: \`🎵 ${title}\`` to `caption: undefined`
- Audio files now show clean filename without emoji prefix

## Result
Audio files now have proper names like "Artist Name - Song Title.mp3" and no caption text, making them cleaner in Telegram chats.
