Description

### Instruction
The problem includes C++ programming on JUCE framework. Follow the instruction, modify the given template code, implement the components using an editor convenient for you (e.g. VIM, VSCode).

### Deliverable
You should submit this project directory, compressed in a single zip file. Please submit it via KLMS.

## Problem #0: Previously… (10 pts.)
“`
float getADSRCurve( float attackTime, float decayTime, float sustainLevel, float releaseTime, bool isRelease, float currentLevel)
{ …
return ADSR;
}
“` “`
float getCurrentSample( float carrierAmplitude, float carrierAttackTime, float carrierDecayTime, float carrierSustainLevel, float carrierReleaseTime, float modulatorAmplitude, float modulatorFreqRatio, float modulatorAttackTime, float modulatorDecayTime, float modulatorSustainLevel,
float modulatorReleaseTime, bool isRelease)
{ …
return Sample;
}
“` “`
void loadPreset(juce::String name)
{ …
}
“`
Replace *getADSRCurve*, *getCurrentSample*, and *loadPreset* functions with your Homework #3 solution.

## Problem #1: Delay (30 pts.)

void process (const ProcessContext& context) noexcept
{ … if (FXType == “Delay”)
{
for (size_t ch = 0; ch < numChannels; ++ch)
{ …
}
}
“`
Implement the delay effect as the above figure by modifying the given code.
Please refer our practice code ’09. Delay-based Audio Effects.ipynb’. You should use Feedback Gain, Delay Time and Wet/Dry Ratio as the control parameter for the delay effect.

## Problem #2: Chorus (30 pts.)

“`
void process (const ProcessContext& context) noexcept
{ … else if (FXType == “Chorus”)
{
for (size_t ch = 0; ch < numChannels; ++ch)
{ …
}
}
“`
Implement the chorus effect as the above figure by modifying the given code.
Please refer our practice code ’09. Delay-based Audio Effects.ipynb’. You should use Delay Time, Wet/Dry Ratio, LFR Rate, and LFO Depth as the control parameter for the chorus effect.

## Problem #3: Flanger (30 pts.)

}
“`
Implement the flanger effect as the above figure by modifying the given code.
Please refer our practice code ’09. Delay-based Audio Effects.ipynb’. You should use Delay Time, Wet/Dry Ratio, LFR Rate, and LFO Depth as the control parameter for the flanger effect.
