LinearSmoothedValue to crossfade between buffers

[oortone]

@danielrudrich

Or even easier: create two of these:
https://docs.juce.com/master/classSmoothedValue.html

call reset (sampleFrequency, rampLength) in your prepareToPlay
set one to gain 0, the other to 1, and switch both when you want to change it again.
in each processBlock call smoothA.applyGain(bufferA) and smoothB.applyGain(bufferB) for each buffer:
https://docs.juce.com/master/classSmoothedValueBase.html#af4a8c2b5a79277406ac6bc2d138efc78

add both to the outputbuffer and you’re all set

Waking this…
Could this be done juce::dsp-style on an AudioBlock too?
I don’t see how, but perhaps…
Could be useful to avoid clicks during sudden changes in realtime.

That is without taking it apart and iteratig of course…
