Linear vs Exponential
Exponential usually sounds more natural to the human ear for volume changes. Linear is mathematically constant and good for crossfading or specific effects.

We use the Web Audio API's precise exponentialRampToValueAtTime to ensure perfectly smooth curves without any "zipper noise" or clicking artifacts.
Frequently Asked Questions
Linear fades sound consistent but can feel abrupt at the end. Exponential fades follow the human ear's sensitivity to loudness, creating a much smoother, professional-sounding silence.
