What is the difference between Linear and Exponential fade?

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.

Can I remove clicks and pops?

Yes! Applying a very short fade (e.g., 0.1s) to the start and end of a clip is the best way to eliminate the mechanical "click" pop sound caused by cutting audio.

Is this good for ringtones?

Perfect. Fade In ensures your ringtone doesn't startle you, and Fade Out prevents it from cutting off abruptly.

Can I preview the fade before downloading?

Yes, you can play the processed audio instantly in the browser to ensure the timing is perfect before you save the file.

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.

常见问题

线性淡入听起来一致，但在结束时可能会感觉突然。指数淡入遵循人耳对响度的敏感度，创造出更平滑、听起来更专业的静音过渡。

可以！在这个片段的开头和结尾应用非常短的淡入（例如0.1秒）是消除由切割音频引起的机械「咔嗒」声的最佳方法。

非常适合。淡入确保您的铃声不会惊吓到您，淡出防止它突然切断。
