CALIBER
v0.1.9 · Windows · FiveM / GTA V Legacy

Weapon soundpack
studio, done properly.

Slot-based editor for FiveM weapon audio, backed by a real DSP pipeline, signed licensing, and atomic install. Built for server operators, RP communities, and content creators who ship.

Built for people who ship packs

Not another one-and-done RPF hack. CALIBER treats weapon audio like the production task it is.

Real audio pipeline

Trim silence, fade edges, per-slot gain, and true peak-or-loudness normalize — all applied before the clip touches the RPF. Preview any slot, A/B against the original stream.

Signed licensing, HWID-bound

Ed25519-signed entitlements bind to your machine. Nonce-echoing anti-replay, offline grace anchored to server-signed timestamps, clock-rollback rejection. Actually secure, not just "obfuscated."

Signed auto-updates

Every update is Ed25519-signed and SHA-512 gated. The client verifies both before touching the installer. A compromised update host cannot ship code to your users.

Every weapon in your game

Weapon list loaded live from your GTA install. Every player container. DLC weapons. Custom FiveM weapons if your server ships them. Not a hardcoded 10 slots.

Sound extraction

Reverse the flow: pull sounds OUT of an existing pack for editing or reference. Auto-pick mode for weapons, dump-every-stream mode when you want to pick by ear.

Atomic install & restore

3-phase swap with marker-file crash recovery. Interrupted install? The next launch rolls the sfx directory back to a coherent state automatically. Your game never boots half-modded.

Refuses to trash your game

Detects and refuses install when GTA V or FiveM is running. Verifies file locks with real Windows APIs, not just process names. Enhanced Edition installs are recognized and refused with a clear message.

My Packs, versioned

Every pack you build is saved with its edits. Come back later, tweak one slot, regenerate. No re-doing your work.

Questions we hear a lot

Does this work with GTA V Enhanced Edition?

No — and CALIBER will refuse with a clear message rather than corrupt your install. Enhanced Edition (2024+) uses a different NG key format that CodeWalker doesn't yet handle. CALIBER targets GTA V Legacy (the original PC release, which Rockstar renamed when Enhanced launched). Legacy is what almost every FiveM server runs.

Which GTA V distributions are supported?

Any Legacy install — Rockstar Games Launcher, Steam, and Epic all ship the same underlying binaries. CALIBER auto-detects your install from the registry, Steam library folders, and Epic manifests. If auto-detect misses your setup, you can point CALIBER at the folder manually.

Will this break my game?

The install path is 3-phase and atomic — backup, stage, swap, verify, then delete staging. Every crash mid-install is recovered on the next launch (marker file + backups). Every install can be reverted with one click. Your stock RPFs are never overwritten without a working backup first.

Can I use custom weapons from my FiveM server?

Yes. CALIBER reads your WEAPONS_PLAYER.rpf live at load time — every container in it appears as a slot. Add a DLC weapon or a custom FiveM weapon and it shows up. Ship a pack that includes it.

What's the reseller model?

The Reseller tier gives you 25 activation keys and a dedicated panel to manage them. You set retail, keep the margin, and see your customers' activations in your own admin view. Popular with FiveM hosting companies bundling custom soundpack tools with their server plans.

What comes with Source Access?

The complete source tree — C# audio engine, Electron desktop app, Node license backend, deploy scripts, tests. Perpetual license to modify and use internally, with optional custom-branding for a fork. Contact sales@demondev.tech for pricing — depends on scope and support level.

Is there a demo?

Not currently — the tool is licensed from install. If you're evaluating for a FiveM server community and want to see a live demo, email sales@demondev.tech and we'll set one up.

What about updates and support?

Signed auto-updates are included with every tier — new features, bug fixes, engine improvements. Support runs through Discord for Individual (community-driven, official response for confirmed issues), and email for Reseller and Source Access.
