Fretboard Map vs Pulsar Tuner

Fretboard Map helps beginning guitarists understand the fretboard visually. Explore the CAGED system, shell voicings, chord tones, and an interactive note map to move beyond open chords and the first three frets. Guided practice paths help you learn roots, octaves, CAGED shapes, and fretboard connections. Hear the notes you are learning with separate recorded acoustic and electric guitar sounds. Play a chord together or hear its tones one at a time as an arpeggio. The acoustic sound uses nylon-string guitar recordings; the electric sound uses pickup recordings with gentle amplifier processing. Both sounds are included for offline playback. Key features: - Diatonic chord diagrams across seven modes, with chord and arpeggio playback - All five CAGED shapes and shell voicings - Triads and major, minor, dominant, and half-diminished seventh chords - Switch between note names and scale degrees - Interactive note learning and guided daily practice - Acoustic and electric guitar playback for notes, chords, and arpeggios - Built-in tuner with 440 Hz, 432 Hz, and 430 Hz reference standards - Landscape layouts for iPhone and iPad - English and Simplified Chinese interfaces No account is required. Build your understanding of chord shapes, note locations, and connections across the guitar neck.

Ultra-precision strobe tuner and versatile acoustic metronome engineered specifically for the acoustics and playing dynamics of the classical guitar. "Why does the open 3rd string always sound muddy in chords even after tuning?" "What is my actual tempo when playing this piece?" "Is my new string defective, or is the 12th-fret intonation off?" "How can I record and loop my practice takes hands-free without putting my guitar down?" Pulsar is a standalone professional acoustic tool designed exclusively for classical guitarists. It integrates 0.1-cent real-time strobe tuning, dedicated temperament modes, smart acoustic tempo detection, string QA diagnostics, timbre physics analysis, and hands-free loop practice recording into a fast, lightweight app. Elevate your daily tuning, practice, and stage preparation with state-of-the-art audio DSP. ------------------------------------- KEY FEATURES ------------------------------------- 1. 0.1-CENT PRECISION STROBE & NEEDLE METER - Real-time phase-accumulating strobe animation running smoothly at 60-120 fps. - Automatic String Detection (1st to 6th string) identifies the plucked note instantly. - 3 tuning operation modes: - Continuous: Smooth real-time tracking. - Auto Snap: Pluck a string and wait for the attack transient to settle; the pitch locks automatically. - Manual Snap: Tap to capture and analyze the most stable pitch trajectory. - Time-series Pitch Ribbon graph and automatic zoom near the target pitch. 2. CLASSICAL GUITAR TEMPERAMENT MODES - 12-Tone Equal Temperament (12-ET): World standard tuning. - Key-Optimized Mode: Eliminates the 3rd-string G beat, sweetening primary triads in major keys (E, A, D, etc.). - Chord-Optimized Mode: Pre-compensates for pitch rise (+2 to +4 cents) caused by low-position fretting tension. - Dyad Beat Tuning: Real-time visualization of acoustic beat frequencies (Hz), periods, and modulation depth between two strings. 3. SMART METRONOME & ACOUSTIC TEMPO DETECTION - Look-ahead audio buffer scheduling for zero-jitter, sample-accurate ticking. - Physics-modeled pendulum visualizer matching mechanical movement with minimal battery draw. - Acoustic Tempo Detection: Analyzes guitar onsets via microphone to calculate and apply BPM instantly. - 1-12 beats per measure, subdivisions (quarter, eighth, triplet, sixteenth), and authentic woodblock, click, and beep sounds. 4. STRING QUALITY ASSURANCE (STRING QA) - Open String Uniformity: Measures decay envelope, eccentricity (unwanted beats caused by non-uniform core), and overtone consistency. - 12th-Fret Octave Intonation: Evaluates intonation errors between the 12th-fret natural harmonic and fretted note. 5. GUITAR TIMBRE ANALYZER - Pluck wizard from string 6 to 1 to objectively measure acoustic timbre metrics. - Computes Spectral Centroid (brightness), Sustain Decay (T30), 1st-8th harmonics, and odd/even harmonic ratios. - Background Isolate processing ensures zero UI stutter during FFT analysis. 6. HANDS-FREE LOOP PRACTICE RECORDER - Record and audition practice takes without taking your hands off the guitar. - Armed Mode: Automatically starts recording on your first plucked note. - Automatic silence detection stops recording and immediately loops playback for objective review. - External metronome debouncing prevents ticking sounds from interfering with silence detection. ------------------------------------- IDEAL FOR ------------------------------------- - Guitarists demanding uncompromising 0.1-cent strobe accuracy - Players seeking pure, sweet harmony by eliminating 3rd-string beat muddiness - Musicians who want to measure their actual performance tempo objectively - Players inspecting new strings for manufacturing defects and intonation errors - Anyone wanting seamless hands-free loop recording during daily practice
