B0daa234/Rhythm-Range

An open-source rhythm-reactive aim trainer where every shot lands on the beat. PulseRanger fuses the adrenaline of a first-person shooter with the precision of a rhythm game, turning raw reaction time into musical muscle memory. Built for players who want measurable progress, esports coaches who crave analytics, and tinkerers who love a modular engine.

Think of it as a metronome that shoots back. Every target spawns to the pulse of the track you choose, and your accuracy is scored against tempo, timing windows, and crosshair discipline — not just clicks per second.

Most aim trainers treat music as background wallpaper. PulseRanger flips the script: the soundtrack is the level design. Targets materialize on downbeats, drift on syncopation, and punish you for spraying off-tempo. The result is a training loop that feels less like a drill and more like a performance — and performers improve faster because they stay engaged.

We built this because reaction training and rhythm training share the same neural machinery: anticipation, timing, and motor precision. Merge them, and you get a single practice space that sharpens both.

• Beat-Synced Target Spawning — targets appear, move, and expire in alignment with user-supplied tempo maps or auto-detected BPM.
• Multiple Training Modes — Flick Rhythm, Tracking Waltz, Precision Polka, and Micro-Flick Metronome.
• Reactive Crosshair Feel — crosshair breathing, punch, and sway respond to the current track's dynamic range.
• Latency Calibration Wizard — measure input-to-photon delay and compensate automatically.
• Deterministic Replay System — every run is reproducible from a seed so coaches can review frame-by-frame.
• Score Fusion Model — combines accuracy, timing deviation, and tempo adherence into a single Pulse Score.
• Preset Library — genre presets from ambient to drum-and-bass, each with tuned spawn curves.
• Offline-First Design — all training data stays on device; optional opt-in sync for teams.

SEO-friendly integrations are baked in: the engine ships with structured metadata for sessions, so external dashboards can index difficulty curves without parsing raw frames.

The heart of PulseRanger is a three-layer pipeline:

1. Analysis Layer — ingests audio, extracts onset envelopes, tempo candidates, and beat grids.
2. Scheduling Layer — converts beat grids into target events using a spawn grammar that respects musical phrasing.
3. Scoring Layer — evaluates each shot against a configurable timing window and geometric tolerance.

The engine is deterministic by design: given the same audio file, seed, and configuration, you get the same session every time. That makes practice comparable week over week and makes bug reports reproducible.

PulseRanger treats every session as a dataset. Out of the box you get:

• Timeline Heatmaps — visualize where in a track you lose accuracy.
• BPM Drift Reports — see if your precision decays as tempo rises.
• Reaction Distribution Curves — compare your median flick latency against your own baseline.
• Streak & Consistency Metrics — beyond simple averages, we surface variance.
• Export to CSV/JSON — feed your own tooling, notebooks, or spreadsheets.

No account is required to view your own numbers. Your data belongs to you.

The interface rearranges itself based on how you train and what hardware you use:

• Windowed, Borderless, and Fullscreen modes with instant toggling.
• DPI-Aware Scaling for ultrawide monitors, laptops, and projector setups.
• HUD Density Presets — Minimal, Coach, and Analyst layouts.
• Touch and Pen Support for tablet-based aim drills.
• Colorblind-Safe Palettes and adjustable reticle contrast.

Everything is designed so that the UI disappears when you're in flow and reappears the instant you need data.

PulseRanger ships with community-maintained translations and a locale kit that any contributor can extend. Interface strings, tooltips, and training descriptions are all externalized into plain resource files, so adding a new language never requires touching engine code.

Current community focus areas include training vocabulary consistency, RTL layout handling, and locale-aware number and date formatting for score reports.

Training questions don't respect time zones, so our community desk is organized as a rotating global relay. Volunteers across regions triage issues, review pull requests, and answer questions in the discussion boards. If you're stuck at 3 a.m. in your local time, there's a good chance someone is awake and already typing a reply.

Support channels include discussion threads, issue templates for bugs and feature proposals, and a contributor handbook for first-time participants.

• Keyboard-Only Navigation for every menu and modal.
• Screen Reader Labels on interactive HUD elements.
• Reduced Motion Mode that preserves timing feedback without rocking orshake effects.
• Audio Cue Alternatives for players who train without sound.
• Scalable Typography with a minimum readable size enforced across panels.

Inclusive design isn't an afterthought here — it's part of the definition of done for every feature.

• Operating Systems — Windows 10/11, modern Linux distributions, macOS 12+.
• Processor — dual-core 2.4 GHz or better.
• Memory — 4 GB minimum, 8 GB recommended for large audio libraries.
• Graphics — any GPU with OpenGL 3.3 or Vulkan support.
• Storage — 500 MB for the core, plus space for your audio collection.
• Audio — any low-latency output device; ASIO/WASAPI recommended for serious calibration.

If you'd rather not touch a command line, PulseRanger offers a portable bundle that runs from a folder. Place the bundle anywhere on your drive, launch the executable, and the first-run wizard walks you through audio device selection, latency calibration, and difficulty selection.

For those who prefer package managers, the project is distributed through common catalogs under the PulseRanger name. The portable route remains the simplest path for newcomers and for machines where you don't have administrative rights.

Sessions are governed by a single human-readable config file. Key sections:

• audio — device selection, buffer size, and onset sensitivity.
• spawning — density curves, target lifetime, and phrase alignment.
• scoring — timing windows, geometric tolerance, and score weights.
• display — resolution, HUD density, and color palette.
• telemetry — export format, retention policy, and anonymization flags.

Every option has a sensible default, and the config file documents itself with inline comments so you can learn by reading.

• Q1 2026 — Public beta of the Beat Grammar editor for custom spawn patterns.
• Q2 2026 — Team dashboards with aggregate Pulse Score trends.
• Q3 2026 — Adaptive difficulty that reacts to your fatigue signals.
• Q4 2026 — Workshop-style community pattern sharing with moderation tooling.

The roadmap is a living document; proposals from the community routinely reshape priorities.

PulseRanger is written up across the ecosystem as an aim trainer with rhythm mechanics, a reaction time trainer for musicians, and a beat-synced FPS practice tool. Contributors are encouraged to write tutorials, benchmarks, and case studies that reference the project naturally — without keyword stuffing, and with real, tested claims.

Whether you're a level designer, a translator, a researcher, or simply a player with strong opinions about crosshair feel, there's a place for you here. Start with the contributor handbook, pick an issue tagged for newcomers, and open a pull request. Small, focused changes are reviewed fastest.

We value clear communication, reproducible bug reports, and a healthy dose of curiosity.

PulseRanger is an independent, community-driven training tool intended for recreational skill development and research into human reaction time. It is not affiliated with, endorsed by, or sponsored by any game publisher, hardware vendor, or esports organization. Performance improvements in this trainer do not guarantee improvements in any specific title. Use responsibly, take breaks, and listen to your body — repetitive strain is real, and your wrists deserve kindness.
