TTFloat64 TTDeviate ( TTFloat64  value, TTFloat64  aSampleRate = 1.0  )

inline

An idiosyncratic utility for slightly randomizing a number.

Specifically this is used in applications such as randoming delay times for a reverb.

Parameters

value	The value to randomise
aSampleRate	Current sample rate

Returns

The slightly randomised value
