In our Generator, the "Session Timer" module plays a central role for both live playback and creating offline files. While both functions rely on the "Duration" you set, they serve two very different purposes. Let's clarify when to use each one.

The Session Timer: For Live, In-Browser Playback

The Session Timer is primarily designed to control **live playback** directly from the website. When you use it, the audio is being generated in real-time by your browser.

• How it Works: You set a duration (e.g., 25 minutes), press the main "Play" button, and a countdown begins. When the countdown reaches zero, the audio automatically fades out and stops.
• When to Use It:
  • For Pomodoro-style focus sprints at your desk.
  • For timed meditation sessions where you don't want to worry about the clock.
  • For falling asleep, ensuring the audio doesn't play all night.
• Requires: An active internet connection and the browser tab to remain open.

The Download Button: For Creating Offline Audio Files

The "Download" button uses the same "Duration" value from the Session Timer, but for a completely different purpose: to define the **length of a portable audio file**.

• How it Works: You set a duration (e.g., 60 minutes), and click the "Download" button. Our engine then works in your browser to render your entire custom soundscape into a high-quality `.wav` file of that exact length. This file is then saved to your computer.
• When to Use It:
  • When you want to listen on your phone during a commute, on a plane, or at the gym.
  • To create a long, multi-hour sleep track to play from your phone without keeping a browser tab open.
  • To archive a perfect preset you've created as a playable audio file.
• Requires: No internet connection *after* the file has been downloaded. The file can be transferred and played on any device.

The Key Takeaway

Think of it this way:

Use the **Play button + Timer** for listening **now**, on your computer.

Use the **Download button + Timer** to create a file for listening **later**, on any device.

Understanding this distinction unlocks the full flexibility of the generator. You can have interactive, live sessions when you're at your desk, and create a library of your favorite custom-made tracks for any situation on the go.
