Frequently Asked Questions
How does Interval Ear Training work?
The tool picks a random root note (MIDI 48-72) and a random interval from your enabled set, then plays both notes using Web Audio API OscillatorNodes. Each note is shaped with a gain envelope for a natural piano-like decay. Your guess is compared to the actual interval, and accuracy statistics are tracked per interval in localStorage.
