Information about SuperTune's high-performance audio engine and cross-platform access.
Traditional tuners require you to pluck each string individually. SuperTune's polyphonic pitch detection analyzes all strings at once when you strum. The visualizer instantly highlights which strings are flat, sharp, or in tune, letting you see which strings need to be adjusted.
Yes and no! SuperTune runs on a proprietary, native C++ digital signal processing (DSP) core compiled directly to WebAssembly. Instead of relying on standard web-audio utilities, SuperTune bypasses browser bottlenecks. This delivers desktop software speed and precision instantly in your browser tab.
