ESSENTIAL TOOLS

The three general tools you are most likely to reach for first: tempo, pitch reference and tuning.

Metronome

40 - 320 BPM, tap tempo, accented beat one and a visual pulse.

Tempo Ramp
Off · enable Ramp mode for progressive speed practice.
Spacebar: Start / Stop · T: Tap tempo

Reference Piano

Real acoustic piano tone for vocal warm ups, tuning and pitch reference.

A4 440.00 Hz
Visible range: C4 - B5
Swipe the keyboard sideways for the full range.
Acoustic piano samples load on first use.
Mouse and touch work directly on the keys. Computer keyboard mapping covers the two visible octaves. Pitch reference uses A4 = 440 Hz. Piano recordings: Salamander Grand Piano V3 by Alexander Holm, CC BY 3.0.

Chromatic Guitar Tuner

Use your device microphone or a direct audio-interface input for guitar, bass, vocals or any single sustained pitch.

PITCH ROOM

Vocal pitch accuracy, fretboard knowledge and guitar hand synchronisation.

Vocal Pitch Trainer

Hear a piano note, sing it back and see how accurately you reach and hold the target pitch.

The selected audio input only starts after pressing Start Pitch Trainer. Audio is analysed locally in the browser and is not recorded, saved or uploaded. Playing the target note temporarily pauses scoring so the piano does not score itself.
Guitar Practice

Fretboard Reflex Trainer

Learn the neck under pressure. Open strings sit before the nut, fret 1 starts the actual fretboard, and the neck can follow 6, 7 or 8-string standard, drop or custom tuning.

6-string standard tuning loaded. The open notes are before the nut; the first fret begins after it.
Guitar Practice

Guitar Hand & Finger Sync Trainer

Coordinate fretting fingers and picking hand against the tempo. Desktop: V / C / X / Z are frets 1 - 4 on the low E string while M is the picking hand. Phone: tilt it landscape like a mini guitar, lock the layout, fret with the four fingers and pick with the thumb.

Double pick: press/hold = downstroke, release = upstroke.
Right-handed mode uses the physical hold tested on phone: PICK left, index finger on F.
Tilt to landscape, then lock.

Pads are live even outside the exercise. Click/tap this trainer once to arm the V / C / X / Z + M keyboard controls, then fret and pick to hear the guitar. During the exercise, match both hands to each note and keep the fret and pick attacks as close together as possible.
Right-handed phone: use the tested mini-guitar hold: PICK sits on the left side of the screen and the fretting buttons run G♯ · G · F♯ · F so the left-hand index finger lands on F.Left-handed phone: the whole playing layout mirrors: F · F♯ · G · G♯ for the right-hand fingers, with PICK on the right. Tilt to the landscape side that feels natural, then press Lock Tilt. The trainer now tries to lock that exact landscape orientation; if the browser requires it, it will enter fullscreen first.

RHYTHM ROOM

Timing accuracy, coordination and hand/foot control.

Timing Trainer

A separate drum practice Tap Pad. It listens to your taps, not your microphone, and measures each hit against the nearest metronome grid point.

Synced with the main metronome.

Consistency--
During an exercise, Spacebar or Enter becomes the Tap Pad. The normal Tap Tempo button is completely separate. Browser/device latency can shift the absolute early/late figure slightly, so consistency across your hits is the most trustworthy practice metric.
Choose your exercise and press Start.

Two-Hand Timing Trainer

Train left/right hand accuracy as alternating strokes, doubles or simultaneous hits. Use the pads on screen or the Left and Right Arrow keys.

Synced with the main metronome.

Pads are live anytime. During scoring you hear the quarter-note metronome while the pads visually show the subdivision. Choose how strict the scoring tolerance should be.
Input latency note

Bluetooth and other wireless keyboards can add input delay. For the most accurate score, use the touchscreen, a wired keyboard/controller, or compare devices before judging the absolute millisecond result. The trainer compensates for a consistent offset, but wireless jitter can still affect individual hits.

Feet / Double-Kick Practice

Foot Timing Trainer

Use your device microphone or another audio input to time foot taps against the metronome. Follow the LEFT / RIGHT cue with the correct foot. A normal mono mic can hear when you tap, but it cannot reliably identify which foot made the sound.

Synced with the main metronome.

Enable the microphone, then calibrate the room while staying quiet. The mic listens only for timing transients; follow the screen cue to choose the correct foot.
How foot detection works

The microphone detects the impact transient, not the identity of your foot. In L - R or R - L mode, you follow the LEFT / RIGHT cue while the mic scores the tap time. The large foot pads can also be tapped on a phone as a test/fallback input while we test locally. Both-feet-together is treated as one combined impact. Soft carpet may need higher sensitivity; hard floors may need lower sensitivity. Microphone practice usually requires HTTPS or localhost browser access.

PRODUCER ROOM

Ear training built around decisions you actually make while producing and mixing.

Production Practice

Frequency Hunt

A hidden EQ boost is added to musical, drum or noise material. Compare the reference and altered sound, then hunt the frequency on a proper logarithmic 20 Hz - 20 kHz scale.

Your selected frequency1.00 kHz

Monitor On turns the slider into an audible frequency sweep for learning. Switch it Off when you want to test yourself properly.
Use A/B as many times as you need, then place the cursor and check your answer.
Production Practice

Audio Reaction Trainer

Train the direction of a mix change instead of memorising random button positions. The left and right choices stay spatially consistent across EQ, level, pan and phase.

Press Start and listen for the change.

Phase challenges use both polarity-style and short-delay comb-filter examples so the advanced rounds can teach the hollow, smeared sound you actually meet while mixing.

Loudness Match

Train yourself not to fall for “louder sounds better.” Match B to the perceived loudness of reference A using only output gain.

A hidden level offset has been loaded into B. A/B the same musical loop, adjust B in real time and match the loudness by ear.
