Dialer's Lab

Active research into push-to-talk, browser audio, and community radio infrastructure — built like a lab, shipped like a product.

Research areas

Half-duplex PTT over the web

Keyed transmit and receive with channel fairness — not VoIP conference rooms or always-open mics.

Mobile survival

iOS and Android background audio, parked listening, headset triggers, and recovery from platform audio kills.

On-device intelligence

Voice conversion, vision screening, speech/music classification — running locally without uploading everything to a cloud farm.

Channel-scale coordination

Multi-channel presence, congestion-aware media delivery, and surgical moderation primitives across many concurrent sessions.

Feature deep-dives

In production

Real Push-to-Talk in a Browser Tab

Half-duplex keyed TX/RX, cooldowns, channel rosters — not Zoom.
In production

Classic Mode for Operators

Strip chaos UI; professional radio feel for serious keyed use.
In production

Parked Listening on iOS

Keep the channel open when Safari wants silence.
In production

Voice Puppet

Character voices converted locally before TX.
In production

Broadcast-Grade Audio

Per-key loudness matching, ear protection, and Web Audio playback chain.
In production

On-Device Safety Gates

NSFW vision + OCR screenshot scan before Feed publish.

Field notes

Field note

Blind Server, Don't Ask Don't Tell

End-to-end delivery through a relay that doesn't ask who you are or hoard what you said.
Field note

When Slow Clients Almost Melted the Radio

Latest-frame-wins delivery when WebSocket buffers fill up on mobile.
Field note

Making iOS Safari Keep the Channel Open

Background tabs, AudioContext suspension, and parked listening recovery.
Field note

Running Voice ML Inside a PWA

WASM, workers, memory limits — voice conversion without a native app.
Field note

We Stopped Pretending Web Apps Can Be Zoom

Why keyed binary media beats conference-call architecture for CB radio.

Currently exploring

  • Bluetooth PTT on more Android builds and headset routing edge cases
  • Richer operator telemetry — busy-channel heuristics and smarter notify-when-hot alerts
  • Smarter parked-listen recovery on flaky networks and format stalls
