Developed by Rajaraman Iyer, the simulator includes experimental support for bellows simulation. On supported devices, you can experience the laptop harmonium with moving flap technology, which uses motion sensors or trackpad gestures to vary the air pressure, just like a physical instrument.
We use the Web Audio API combined with optimized buffer cycles to ensure near-zero latency. This makes our virtual harmonium suitable for professional live performances and recordings.
While many harmonium websites offer basic sound, Web Harmonium focuses on the nuance of sound. Our additional reeds and adjustable reverb parameters allow you to customize the timbre to match different musical genres, from Khyal to Ghazals.
