Formula and methodology
Formula: Adjusted duration = original duration/playback speed; time saved = original − adjusted duration.
A constant playback multiplier changes elapsed listening time while the audio content remains the same.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Original duration — minutes; minimum 1.0E-6; maximum 1000000
- Playback speed — ×; minimum 0.01; maximum 100
Worked example
| Input | Value |
|---|---|
| Original duration | 600 |
| Playback speed | 1.25 |
Adjusted time = 480 minutes; saved time = 120 minutes.
Assumptions and limits
- Playback speed is constant from start to finish.
- The original duration is positive and measured in minutes.
- Pauses, chapter transitions, comprehension, and device limits are not modeled.
