Pulsar Tuner: Classical Guitar

[Ultra-Precise Strobe Tuner & Acoustic Metronome for Classical Guitar] Pulsar Tuner is a dedicated tuning and practice app engineered specifically for the acoustic and physical characteristics of the classical guitar. - Tired of erratic needle tuners that never settle? - Want to eliminate third-string beating and low-fret sharpness? - Need a metronome that automatically calculates your playing tempo? - Wish to review your phrasing hands-free without putting down your guitar? Pulsar Tuner solves these challenges with professional audio DSP in a lightweight, instant-launch app. ---------------------------------------- KEY FEATURES ---------------------------------------- 1. Ultra-Precise Strobe & Needle Display (+/-0.1 Cent) - Real-time phase-accumulating strobe display emulating mechanical wheel behavior (clockwise: sharp, counter-clockwise: flat, stationary: in-tune). - Automatic String Detection: Pluck strings 1 to 6 and tune without touching the screen. - Auto Snap (SettleDetector): Skips transient plucking noise and automatically locks pitch the millisecond the tone stabilizes. - Pitch Ribbon: Visualizes pitch trajectory over time with automatic zoom near target frequencies. 2. Dedicated Classical Guitar Tuning Modes - 12-Tone Equal Temperament (12-ET): Standard universal tuning (0.0 cent offset on all strings). - Key Optimization: Automatically calculates pitch offsets for major keys (E, A, D) to eliminate 3rd-string beating and purify chords. - Chord Compensation: Offsets fretting tension sharpness (+2 to +4 cents) on lower frets across open strings. - Dyad Beat Tuning: Real-time visualization of acoustic beat speed (Hz), period, and modulation depth when plucking two notes together. 3. High-Precision Acoustic Metronome - Jitter-free audio playback powered by look-ahead buffer scheduling. - Physical Pendulum Visualizer: Recreates smooth mechanical pendulum swing while minimizing battery drain. - Acoustic Tempo Detection: Analyzes plucking onsets via microphone to estimate live BPM and apply it with a single tap. - Flexible Settings: 1-12 beats, subdivisions (quarter, eighth, triplet, sixteenth), and authentic woodblock sounds. 4. String Quality Diagnostics (String QA) - Detects core flaws and unrounded shapes (unwanted beating) in new strings. - Objectively scores open-string decay envelopes and harmonic uniformity. - Measures octave intonation (12th-fret harmonic vs. fretted note) to assess string health and saddle compensation. 5. Hands-Free Loop Practice Recorder - "Armed" Mode: Monitors the microphone and automatically starts recording upon your first plucking onset. - Auto Stop & Loop Playback: Detects 2.2 seconds of silence after your phrase, stops recording, and immediately loops playback. - Evaluate tone, touch, and timing without ever taking your hands off the guitar. - Export studio-quality audio in WAV, FLAC, or AAC formats. 6. Built for Optimal Performance - Mic Gain Calibration: Automatically suggests optimal input gain for your device and microphone environment. - Screen Keep-Awake: Prevents display sleep while tuning so you can focus entirely on playing. ---------------------------------------- IDEAL FOR GUITARISTS WHO WANT TO: ---------------------------------------- - Experience responsive, jitter-free strobe tuning that never jumps erratically. - Scientifically eliminate chord dissonances and fretting pitch drift. - Develop rock-solid timing while tracking their actual playing tempo. - Quickly diagnose false strings and octave intonation problems. - Practice seamlessly in repeating loops without touching recording buttons.
