Added left/right ear training under Frequency Ear Training — a different band is boosted or cut in each ear, and you identify both independently. Added noise type, hum frequency, and noise floor detection under Noise Ear Training, all with optional background music. Added A/B effect-intensity comparison training. Added a 10-question mock exam (Basic/Pro) to check everything you've trained at once. Also improved playback stability and volume balance throughout.
