The definitive all-in-one acoustic suite and gear manager designed exclusively for classical guitarists and luthiers. Powered by our proprietary DSP acoustic engine, ReString elevates your playing with ultra-precise strobe tuning, physical string quality diagnosis, objective practice analytics, and comprehensive string lifecycle tracking.
Key Features
1. Advanced Acoustic Strobe Tuner (±0.1 Cent Precision)
Real-time Strobe Engine: Smooth rotating animation and dynamic pitch ribbon with automatic zoom for microtonal tuning accuracy.
Key & Chord Sweetened Tuning: Mitigate classical guitar’s notorious 3rd-string beat muddiness and offset natural fretting sharping (+2 to +4 cents on low positions).
Dyad Beat Tuning: Visualize acoustic beat frequencies (Hz) and modulation rates in real time when playing two notes simultaneously.
Presets & Custom Profiles: Standard, Drop D, Double Drop D, Lute tuning (3rd F#), DADGAD, and custom temperaments.
2. String Quality QA & Defect Detection (Uniformity Analyzer)
Unroundness & Beat Modulation: Analyze open string resonance to detect core wire inconsistency, eccentric thickness, and harmonic disuniformity.
12th Fret Intonation Check: Compare open vs. 12th fret harmonics and pressed frets to spot false strings and intonation flaws.
Objective QA Score: Instant 100-point rating and radar charts to safeguard against defective string batches and track aging wear.
3. Practice Analyzer & Acoustic Feedback
Tremolo (p-a-m-i): Separate high-speed strikes up to 790 bpm, quantifying rhythmic spacing, note clarity, and dynamic consistency.
Arpeggios: Isolate high-string attacks despite bass resonance, measuring balance and projection across voices.
Alternating Stroke Scale (i-m / m-a / i-a): Measure timing intervals, velocity balance, and spectral brightness on our intuitive 50%:50% balance bar.
Harmonics Spectral Purity: Dual-peak meter measuring decibel ratio between target overtone and residual fundamental leakage (12F, 7F, 5F, artificial).
4. Acoustic Metronome & DSP Tempo Detection
Tempo Reverse Calculation: Detects your playing attack onsets via microphone to automatically estimate and lock your natural BPM.
Acoustic Sound Library: Natural woodblock and subtle tick samples designed to blend harmoniously with acoustic nylon instruments.
Subdivisions & Time Signatures: From 1 to 12 beats, triplets, 16ths, and intuitive tap tempo.
5. Active Strings Dashboard & Inventory Management
Active String Status: Monitor mounted strings, installation dates, elapsed days, and tension at a glance.
Custom Mix Support: Register hybrid string configurations (e.g., carbon trebles paired with nylon basses).
Bento Grid Dashboard: Beautifully organize multiple guitars, maintenance reminders, and string wear.
Inventory Stock Tracking: Manage spare sets and single strings at home; log string changes with one tap.
6. String Specs Database & Tone Recordings
Comprehensive Catalog: Specs, tensions, and materials for Savarez, D'Addario, Augustine, Hannabach, Knobloch, La Bella, Aquila, and more.
Built-in Audio Diary: Record and compare sound clips across string lifecycles and different guitar woods.
Cloud Sync: Seamless multi-device synchronization powered by Firebase.
