midpoint the shape is not linear. There are also two types of S-curves. Traditional S-curve fade-in has attributes of the exponential curve can be seen at the beginning; at the midpoint to the end it is more logarithmic in nature. A traditional S-curve fade-out: is logarithmic from the beginning up to the midpoint, then its attributes are based on the exponential curve from the midpoint to the end. This is true for the situation in reverse as well (for both fade-in and fade-out). Crossfading S-curves works as follows; it diminishes the amount of time that both sounds are playing simultaneously. This ensures that the edits sound like a direct cut when the two edits meet - this adds an extra smoothness to the edited regions. The second type of S-curve is more apt for longer crossfades, since they are smooth and have the ability to have both of the crossfades in the overall level; so that they are audible for as long as possible. There is a short period at the start of each of the crossfades where the outgoing sound drops toward 50% quickly (with the incoming sound rising just as fast to 50%). This acceleration of sound slows and both sounds will appear as if they are at the same level for most of the crossfade (in the middle) before the changeover happens. DAW's gives one the ability to change the shape of logarithmic, exponential, and S-curve fades and crossfades. Changing the shape of a logarithmic fade will change how soon the sound will rise above 50%, and then how long it takes for the end of the fade-out to drop below 50% once again. With exponential fades the shape change will affect the shape in reverse, to the shape of the logarithmic fade. In the S-curve's traditional form the shape determines how quickly the change can occur and in the type 2 curve the change can determine the time it takes for both the sounds to get to a nearly equal level. Fade times It is also possible to apply different fade times to the out and in portions; which a standard crossfade would not allow you to apply. Appropriate fade-in time for a linear fade can be around 500ms; for the fade-out 500ms would also be affective. By having this longer fade it makes sure that everything is gentle as it gives the fade time to
