🎹 OOSC!

OOSC is a two-oscillator wavetable driving synthesizer written with Qt, QML and C++. Have some included effects like a Reverb, Flanger, EQ etc. Built-in MIDI-file playback. Support automation using ADSR and LFO. Visualized audio output by channel, vectorscope, FFT.

🎼 Oscillator features

• Load wavetable from any wav-file
• User-control parameters
  • Pan, Gain, Wavetable position, Phase, Octave offset, Semitone offset, Cents, Unison voices, Unison cents range, Unison gain range
• Seed for unison randomization
• Multi-thread

📈 Envelope features

• Simple Attack-Decay-Sustain-Release, but..
• Cubic Bézier curves for transition
• May be connected to any user-controlled parameter

🐢 Low-frequency oscillator features

• Four shapes
  • Sine, Sawtooth, Triangle, Square
• Changeable frequency & phase
• May be connected to any user-controlled parameter

🔮 Visualization

• Left & Right output wave
• Vectorscope
• Fast Fourier Transform

✨ Effects

• Delay, Chorus, Phaser, Flanger, Reverb, Distortion, Vibrato, EQ, Compressor

🔧 Build

cmake -S <project_directory> -B <build_directoty>
cmake --build <configuration>

For example:

cmake -S . -B Debug
cmake --build Debug

<configuration> is Debug, Release, MinSizeRel, or RelWithDebInfo.

... or just open as projects in QtCreator, CLion or any other c++ IDE, that support CMake and build.

🔩 Requirements

• Compiler that support C++17
• Qt 5.15 +
• Portaudio API 2.0
• CMake 3.14 +
