🎧 About the audio samples on PlayPianoOnline

We use high-quality pre-rendered audio files (MP3/OGG) generated from the FluidR3_GM SoundFont via the midi-js-soundfonts pipeline. This ensures realistic piano dynamics, sustain, and rich harmonic response. The samples are loaded on-demand, providing a seamless, low-latency playing experience directly in your browser — without any plugins. Every note you play is powered by this open community resource.

💡 No proprietary samples are used. The sound is entirely generated from the FluidSynth FluidR3_GM source, making the interactive piano possible while respecting free culture licensing.
