A powerful and intuitive Digital Synthesizer built with Flutter. This utility combines the core principles of sound synthesis with a high-performance real-time oscilloscope, allowing users to design and visualize audio waveforms simultaneously.
- Four Core Waveforms: Instantly switch between Sine, Square, Sawtooth, and Triangle waves.
- Real-time Oscilloscope: Visualize sound waves as they are generated, perfect for understanding acoustic physics.
- Precision Tuning: Adjust frequencies via intuitive sliders or direct Hz-level numeric input for exact pitch control.
- LFO Modulation: Add depth and character with dedicated Frequency and Depth controls for vibrato and effects.
- Spatial Control: Integrated stereo panner to manage the audio’s position in the stereo field.
- Responsive Keyboard: A piano-style interface optimized for any screen size, providing a comfortable performance experience.
- Sound Designers: Creating unique sound effects (SE) for games or videos.
- Music Students: Learning the fundamentals of synthesis and waveform characteristics.
- Synthesizer Enthusiasts: A lightweight, high-quality tool for quick inspiration and sonic experimentation.
- Framework: Flutter
- Language: Dart
- Logic: Low-latency audio buffer generation and custom Painters for real-time waveform visualization (oscilloscope logic).
