How Voice Stream Works
After entering the announcement text, the system first generates a voice file using Microsoft Edge TTS. The voice announcement and selected background music are then mixed in the browser. The music starts with a five-second intro, continues playing during the announcement, and automatically fades out after the voice recording ends.
- 5-second music intro
- Voice announcement at 100% volume
- Background music at 70% volume
- Automatic fade-out over 5 seconds
- Export as MP3 file at 128 kbps
Background Management
In the Voice Stream section, any number of MP3 files can be uploaded as background music. Each file can be assigned a custom name for quick selection later in the streaming module.
- Multiple MP3 file uploads
- Custom names for each music file
- Direct playback for preview
- Delete files including server cleanup
