1. Load Your First Audio File
- Click Browse in any track slot (A, B, C, or D).
- Or drag and drop an audio/video file directly onto a slot.
- Wait a few seconds while the app analyzes it.
- You’ll see the filename and loudness level appear in the slot.
2. Hear Your Audio at Original Volume
- Click on the track name in the slot.
- Your audio plays at its original loudness.
- You can now jump around using the slider if needed.
3. Pick a Platform to Test Against
- Click one of the platform names: Spotify, Apple, Instagram, YouTube, Amazon, or Deezer.
- The selected platform is now your target.
- The app shows you how your audio compares to that platform’s loudness standard.
4. Hear Your Audio Adjusted for That Platform
- Click any cell in the row for your selected platform.
- Your audio plays adjusted to match that platform’s standard.
- If your audio is quieter than the platform standard, the app leaves it as is — it only reduces volume when needed.
5. Switch Between Original and Adjusted
- Use the Loudness Match toggle to quickly flip between:
- Original: your audio at its normal volume
- Adjusted: your audio tuned for the platform
- You’ll hear the difference clearly.
6. Load More Files to Compare
- Load different audio files into slots B, C, or D.
- Click the same platform and then different cells in that row.
- This lets you hear how each of your files sounds at the same loudness level.
- Great for spotting which files need the most adjustment.
7. Try “Quietest Loaded Track”
- Once you have 2 or more tracks loaded, the Quietest Loaded Track option becomes available.
- Use this to see how all your files sound at the same level as the quietest one.
- Click that row, then click cells to audition.
8. Use Playback Controls
- Play: starts or resumes playback.
- Pause: stops and remembers your position.
- Stop: resets to the beginning.
- Slider: jump to any spot in the track.
Next Steps
Now that you know the basics, try:
- Loading a few different tracks and comparing them across platforms.
- Using the slider to audition different sections at each platform’s loudness.
- Toggling between original and adjusted while playing to hear the real difference.
- Checking your platform’s official guidelines to make sure these targets work for you.
