Fade Audio, Every Setting: Curves, Length, Seamless Loops (Free)

Every setting of the free Fade Audio tool on a 20-second track that stops dead: the Podcast preset (half a second each end), Song ending (5 s logarithmic fade out), the six curves shown on the waveform, Ends at 15 s with the rest trimmed (20 s in, 15 s out), fading to a level instead of silence, and the Seamless loop (a 4 s crossfade — 16 s out, with no seam when it repeats). Three jobs you can hear. Nothing is uploaded.

Fade Audio, every setting, on a 20-second music loop that stops dead. The waveform shows the fade on your audio before anything is rendered, and Play with fade previews it. The Podcast preset fades half a second at each end — enough that room noise does not snap on and off. Song ending fades five seconds out on a logarithmic curve. Six curves shape the fade: linear, equal power, smooth, exponential, logarithmic and steep. A fade can sit anywhere: set Ends at to 15 seconds and tick End the file at the fade out, and the file is cut there. Fade to a level dips music to a floor under a voice instead of to silence. Seamless loop crossfades the end into the start so the file can repeat forever — 16 seconds out with a 4-second overlap. Free processes one file up to 50 MB and 30 minutes, with fades up to 30 seconds. Nothing is uploaded.
