![A sponsored social media post by Brian Wampler promoting a beginner’s course on digital guitar effects. The text at the top reads: “You already build analog pedals. Now build digital! Delays, reverbs, pitch shifters, anything your mind can think of, you can create way easier and faster than you ever imagined. Sascha Suhr's Complete Beginner's Guide to Digital Guitar Effects is 30% off right now with code DIGI30OFF. 30-day money-back guarantee. No coding background required!”
Below is a split image.
Left side headline: “What you think digital pedal building requires:” followed by a full screenshot of C++ code for a Daisy Seed DSP project:
#include <daisy_seed.h>
using namespace daisy;

#include "dsp/tremolo.h"

float flutter_amount = 0.0005f;
float feedback_amount = 0.4f;
void AudioCallback(AudioHandle::InputBuffer in, AudioHandle::OutputBuffer out, size_t size)
{
for (size_t i = 0; i < size; i++)
{
float input = in[0][i];
float wet = 0.0f;
float dry = input;
wow.Process(wow_amount);
flutter.Process(flutter_amount);
float current_delay = 48000.0f * 0.5f; // 500ms base
current_delay += wow.GetFrequency() * 100.0f + flutter.GetFrequency();
delay_buffer.SetDelay(current_delay);

float feedback = wet * feedback_amount;
delay_buffer.Write(input + feedback);
