AMF Audio Lab
Train Your Ears
Browser-based audio tools built around the Plogger Method. Hear di-chords by their acoustic fingerprint, not their names. All four chambers, from day one.
Ear Training
Di-Chord Explorer + Drill
Train your ears on the three Plogger sound factors — pulsation, harmonicity, and F/O direction. Drill any sprint's focus di-chords until they're Stage 3.
Jam Tracks
Progression Playback
Practice the 14 core progressions in any key with selectable instruments. Connects directly to each sprint's Gate A harmonic root movement.
Rhythm Trainer
8-Position Grid + Metronome
Build groove from the binary grid up. Enter patterns, hear them loop, work toward Son Clave. Longy rhythm notation alongside every grid.
Interval Trainer
Melodic Recognition
Melodic interval recognition in the Melody Chamber context. Zone-aware prompts connect each interval to its di-chord acoustic fingerprint.
The Goal
These tools exist to make the Plogger sound factors perceptually real, not intellectually known. You don't memorize that [3] is “4Hz, non-harmonic, refers down.” You hear it, feel it, and eventually stop needing the label. The framework disappears.
