Detailed Description

This implements a Trapezoid window using the following algorthim:

Where 0. <= x <= 1. and 0. <= mAlpha <= 1.: y = x * twoOverAlpha : for the attack = 1 : for the sustain = (1 - x) * twoOverAlpha : for the release

TTFloat64 TrapezoidWindow::mAlpha

protected

Set the alpha attribute of the Trapezoid window function.

Parameters

newValue The new value to apply.

Returns: TTErr error code if the method fails to execute, else #kTTErrNone.ratio of window fades to total window duration. 0 <= alpho <= 1., 0 = no fades, 1 = no sustain
