A Comprehensive Toolkit for Musicians
PitchMaster Tools was built by a musician/engineer vibe-coding with Gemini Flash, for musicians. Whether you are a beginner learning to tune your first guitar, or a professional cellist practicing intonation with a continuous drone, our tools are engineered for maximum accuracy.
Unlike standard apps that force you to create accounts, PitchMaster is instantly available in your browser. We leverage the modern Web Audio API to deliver millisecond-accurate pitch detection and audio generation. This means our Chromatic Tuner can detect fractions of a cent, our Tone Generator produces mathematically perfect sine waves, and our Audio Analyzer runs a high-speed Fast Fourier Transform (FFT) in real-time.
Explore the tools above, read our extensive guides on music theory and practice techniques on each tool page, and elevate your musical journey.
