Audio Fade
Add fade-in and fade-out ramps — kill the clicks, smooth the ends.
About this tool
Two sliders — fade in, fade out, each up to ten seconds — applied as clean linear ramps and exported as WAV. Preview before downloading. Simple on purpose.
Why cuts click, and fades fix it
Cut audio anywhere but a zero-crossing and the file jumps instantly from silence to mid-waveform — and that discontinuity IS a click, as audible as a scratch on vinyl. It's the most common flaw in home-trimmed audio, and the fix is embarrassingly small: even a 20-millisecond fade replaces the jump with a ramp and the click vanishes, which is why professional editors fade every single cut by reflex. Beyond click-repair, fade lengths are a language: half a second reads as tidy, one to two seconds as an intro, three-plus as cinematic; and the long fade-out remains music's traditional solution to songs without endings. Chain order for clean results: trim to the content, fade the ends, then normalize — fading after normalizing slightly lowers the peak, which rarely matters but bothers perfectionists. The looper uses crossfades (a fade-out overlapping a fade-in) to make repeats seamless — same principle, both directions at once.
Frequently asked questions
Why does my trimmed audio click at the start?
The cut landed mid-waveform — the instant jump from silence to signal is audible as a click. A fade-in as short as 0.05 s removes it completely.
How long should fades be?
0.05–0.2 s to kill clicks invisibly; 1–2 s for a musical intro; 3+ s for drama. For podcast beds under speech, 2–3 s out is the norm.
Are the fades linear or curved?
Linear — a straight volume ramp, which sounds right for the vast majority of material and keeps the tool honest and predictable.
Can I fade just one end?
Yes — set the other slider to zero. A fade-out-only is the classic song ending; fade-in-only fixes an abrupt start.
