FFmpeg afade/acrossfade filter curves illustration
The table below shows visual illustrations of how the volume of an audio stream changes when they are faded-in, for a given curve type. For fade-outs, the horizontal mirror of the illustration represents that effect.
| afade argument | Meaning | Curve |
|---|---|---|
| tri | triangular, linear slope (default) | 
|
| qsin | quarter of sine wave | 
|
| hsin | half of sine wave | 
|
| esin | exponential sine wave | 
|
| log | logarithmic | 
|
| ipar | inverted parabola | 
|
| qua | quadratic | 
|
| cub | cubic | 
|
| squ | square root | 
|
| cbr | cubic root | 
|
| par | parabola | 
|
| exp | exponential | 
|
| iqsin | inverted quarter of sine wave | 
|
| ihsin | inverted half of sine wave | 
|
| dese | double-exponential seat | 
|
| desi | double-exponential sigmoid | 
|
| losi | logistic sigmoid | 
|
| nofade | no fade |
