Classes
class	CachedVolumeControl
	In order to optimize the processing time we cache the last input & factor and recalculate the new factor only if the input has changed. More...
class	CallbackVolumeControl
	Provide the volume function as callback method: This is easy to use e.g together with a lamda function! More...
class	ExponentialVolumeControl
	Simple exponentional volume control using the formula pow(2.0, input) - 1.0;. More...
class	LinearVolumeControl
	The simplest possible implementation of a VolumeControl: The input = output which describes a linear curve. You would use this implementation if you physically connect an audio pot! More...
class	LogarithmicVolumeControl
	Parametric Logarithmic volume control. Using the formula pow(b,input) * a - a, where b is b = pow(((1/ym)-1), 2) and a is a = 1.0 / (b - 1.0). The parameter ym is determining the steepness. See https://electronics.stackexchange.com/questions/304692/formula-for-logarithmic-audio-taper-pot. More...
class	SimulatedAudioPot
	Simple simulated audio pot volume control inspired by https://eepower.com/resistor-guide/resistor-types/potentiometer-taper/# We split up the input/output curve into 2 linear pieces with a slow and a fast raising part. The slow raising part goes from (0,0) to (x,y). The fast raising part goes from (x,y) to (1,1). More...
class	VolumeControl
	Abstract class for handling of the linear input volume to determine the multiplication factor which should be applied to the audio signal. More...
class	VolumeOutput
	A simple class to determine the volume. More...
class	VolumeStream
	Adjust the volume of the related input or output: To work properly the class needs to know the bits per sample and number of channels! AudioChanges are forwareded to the related Print or Stream class. More...
class	VolumeSupport
	Supports the setting and getting of the volume. More...
