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.

💡Quick Answer

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.

Questions Fréquemment Posées

Les fondus linéaires sonnent constants mais peuvent sembler abrupts à la fin. Les fondus exponentiels suivent la sensibilité de l'oreille humaine, créant un silence beaucoup plus doux et professionnel.

Oui ! Appliquer un fondu très court (ex. 0.1s) au début et à la fin d'un clip est le meilleur moyen d'éliminer le "clic" mécanique causé par la coupe audio.

Parfait. Le Fondu Entrant assure que votre sonnerie ne vous sursoit pas, et le Fondu Sortant l'empêche de se couper brusquement.
