🚀 Quick Start¶

Build¶

mkdir build && cd build
cmake ..
cmake --build .

Run Examples¶

# Delay effect
./examples/delay_effect

# Lookahead limiter
./examples/lookahead_limiter

# Wavetable synth
./examples/wavetable_synth

Run Tests¶

ctest --output-on-failure

📚 Components¶

DelayBuffer¶

Circular delay buffer with fractional delay support:

#include "delay_buffer.hpp"

DelayBuffer delay(48000);  // 1 second max
delay.write(input);
float output = delay.readLinear(12345.67f);  // Fractional delay

LookaheadBuffer¶

Buffer for lookahead processing (limiters, compressors):

#include "lookahead_buffer.hpp"

LookaheadBuffer lookahead(240);  // 5ms at 48kHz
lookahead.write(input);
float peak = lookahead.getPeakLookahead();
float delayed = lookahead.readCurrent();

CrossfadeBuffer¶

Dual buffer for smooth crossfading:

#include "crossfade_buffer.hpp"

CrossfadeBuffer xfade(2048);
xfade.setBufferA(wavetable1, 2048);
xfade.setBufferB(wavetable2, 2048);
float sample = xfade.read(index, 0.5f);  // 50% crossfade

✅ Features¶

✅ Zero-allocation in audio thread
✅ SIMD-friendly data layout
✅ Fractional delay with interpolation
✅ Memory pooling for temporary buffers
✅ RAII resource management
✅ Comprehensive test coverage
