juce::AudioBuffer& buffer

Every audio component shares one buffer(noitice the &) when "void process" in according files.

In PluginProcessor.cpp processBlock(), noise is the first audio component who process(buffer), so we can write "data[] = " in Noise.h process(). Waveform and others which below noise should write "data[] += " in according files process().

Ramp and Loops

Nested order of double loops:

1. channel-wise

for(channel){
    
    auto* data = buffer.getWritePointer(channel);
    
    for(sample){
        float currentGain = smoothedGain.getNextValue();
        // ...
    }
}

Execution process analysis:

1. Enter channel 0 (left channel)
   • sample = 0, getNextValue() = 0.1
   • sample = 1, getNextValue() = 0.2
   • ...
   • sample = 3, getNextValue() = 0.4
   • Left channel finished.
2. Enter channel 1 (right channel)
   • sample = 0, getNextValue() = 0.5
   • sample = 1, getNextValue() = 0.6
   • ...

We can hear gain ramp in left channel, but the right channel is begin with 0.5
This sound may left-right imbalance

2. sample-wise

for(sample) {
    
    const float currentGain = smoothedGain.getNextValue();
  
    for (channel) {
        auto* data = buffer.getWritePointer(channel);
        // ...
    }
}

Execution process analysis:

1. sample = 0, getNextValue() = 0.1

• left = 0.1, right = 0.1

2. sample = 1, getNextValue() = 0.2
   -left = 0.2, right = 0.2
