b3LAB
b3LAB builds focused macOS utilities for moving live visuals between apps, hosts, cameras, audio-reactive systems, and delivery formats. Built by one creative technologist for real production friction — no bloat, no subscription lock-in, no vague compatibility promises.
// SIGNAL CHAIN
What b3LAB connects.
Four bridges across the awkward gaps between live, post, presence, and delivery. Use one tool where the workflow breaks — or stack the full chain.
Routing
Realtime apps → Post tools
Route Syphon and NDI sources directly into DaVinci Resolve Studio, Assimilate Scratch, and LiveFX. No capture-card detour, no export loop.
Control
Audio → Visual control
Turn mic, file, or soundtrack input into 52 structured OSC values for TouchDesigner, Resolume, MadMapper, Synesthesia, VDMX, Max.
Presence
Syphon / NDI → Camera output
View, multiview, correct, record, and expose live visual sources as a system-wide virtual camera for Zoom, Teams, Safari, FaceTime, OBS.
Delivery
Rendered output → Show assets
Batch-create HAP, ProRes, HEVC, H.264, WebM, image sequences, and audio masters locally — no CLI, no cloud, no telemetry.
// PRODUCTS
Four tools. One signal chain.
Each tool sits at a clear point in the b3LAB signal chain — control, routing, presence, and delivery. Use one where the workflow breaks, or connect the full chain.
b3LAB – Routing Layer
PortalOFX+ early access
OFX Suite (4 plugins) · macOS · €39 EA
Route Syphon and NDI signals into and out of DaVinci Resolve Studio and Assimilate Scratch / LiveFX. Four plugins (Syphon IN/OUT + NDI IN/OUT) under one license. No capture card, no screen-share workaround — live frames inside the timeline, then back out again.

PulseOSC+ stable
OSC · FFT · BPM · macOS · €19 / €79
Turn audio into visual control. Broadcast 52 structured OSC values from mic, file, or video audio to TouchDesigner, Resolume, MadMapper, Synesthesia, VDMX, Max. BPM tracking, hit detection, frame-accurate OSC recording, and a shared-memory spectrum texture for visualization patches.

b3WebCam+ early access
App + OFX · System Extension · macOS · €19
A Syphon / NDI signal hub: view, multiview, flip/flop correction, no-signal slate, built-in recorder (ProRes / H.264 / HEVC), and system-wide virtual camera output for Zoom, Teams, Safari, FaceTime, OBS. Or drop the OFX directly on a Resolve clip and write straight into b3WebCam+, no app needed. Audio routing via the BlackHole helper.
b3LAB – Delivery Layer
BatchForge+ stable
Encoder Suite (4 modes) · macOS · €19 / €39 / €79
Turn realtime output into show assets. A native macOS FFmpeg workbench with four modes — Batch Transcode, Audio-Only, Segment Join, Image Export. ProRes / HAP / HEVC / H.264 / WebM with hardware acceleration where available, EBU R128 loudness mastering, Watch Folder + JSON presets, full preflight validation.

Choose the signal chain you need.
Each bundle is a workflow configuration — not just a discount. Pick the stack that matches how your signals move from audio, to realtime visuals, to camera, post, and delivery. One-time purchase, no subscription.
b3LAB – Live Stack
Live Stack control
PulseOSC+ Personal + b3WebCam+ EA · €30 (€38)
For audio-reactive performance, streaming, teaching, and remote presence. Drive visuals from audio with PulseOSC+, then expose the result as a system-wide camera with b3WebCam+.
View Live Stack →b3LAB – Hybrid Stack
Hybrid Stack routing
PortalOFX+ EA + BatchForge+ Pro · €65 (€78)
For realtime-to-post workflows: live ingest, finishing, and clean delivery. PortalOFX+ routes Syphon and NDI into Resolve or LiveFX; BatchForge+ turns the result into ProRes, HAP, HEVC, or WebM masters.

Built for real problem solving.
b3LAB is Benjamin Mauz — creative technologist, editor, live-vision mixer, occasional camera guy, digital arts lover, and 8 bytes of nerdity.
About the tools: it started as a side-hobby alongside my main work. I wanted to optimize my own workflow and work less — but the things I needed either didn't exist, or existed badly. PortalOFX+ started because I wanted live Syphon/NDI input and output in Resolve — for direct local and network screening, and to work with Resolve in ways that just weren't possible before. So I started writing my own Python tools, got confident with it, and thought I could do more — which I've since rebuilt as proper native macOS apps. And now I'm convinced they should reach the world — for a good meal and a few beers.
Built by someone who'd rather make the tool right than make it big.
The focus is narrow by design. b3LAB tools do one job reliably. No feature explosion. No universal compatibility promises. No roadmaps that turn into vaporware. Just focused, honest utilities for people who know exactly why they need them.
I work at the intersection of realtime graphics, post-production, and creative infrastructure — through OFX plugins, native macOS apps, Python utilities, and the occasional GLSL shader when nothing else fits.
