Built for DAB+, FM & HD Radio broadcasters

Your online stream, in lockstep with your broadcast

FM-aligned simulcast for DAB+, FM, and HD Radio broadcasters. Tell us your chain offset; we hold it across every device tuned in — phone, laptop, smart speaker, bar TV — with sub-millisecond precision on the same network.

Aligned with every broadcast mode

DAB+ FM HD Radio AM DRM+ Web & mobile

Your transmitter and your app aren’t on the same beat

A listener with FM in the kitchen and your app on a phone hears the same song 5–15 seconds apart. Two phones in the same bar, tuned to your online stream, drift by 8 seconds. Your morning host counts “3, 2, 1” — and the audience reacts in fragments. Every other streaming stack ships this drift. We hold one beat across every device.

Three pillars built for broadcasters

Not another internet-radio host. A streaming layer designed around your transmitter chain, your royalty obligations, and your audience scale.

Aligned to your broadcast

Tell us your transmitter chain offset; we hold it across every device tuned to your online stream. NTP-over-WebSocket clock sync, scheduled Web Audio playout. Sub-millisecond drift on the same network, under 10 ms across the public internet.

Δt < 10 ms cross-WAN

Drop-in player, every surface

One script tag on your station site. Same engine inside your iOS and Android app webviews, on smart speakers, on partner sites. Custom colors, your domain on higher tiers. Nothing to install on your studio side.

1 script tag · works everywhere

Drive-time-ready infrastructure

Dedicated EU and US edge nodes auto-scale through your daily peak. Soft-capped overage means a viral moment never blocks a listener. Up to 99.99% SLA with service credits at National tier.

Peaks 5–10× off-peak · handled

From STL to listener, in three steps

No rip-and-replace. Sonotiq sits alongside your existing transmission chain.

1

Point us at your stream

Give us your existing Icecast or Shoutcast URL — the same feed your current online listeners hit. Or pull from your studio automation (RCS Zetta, WideOrbit, ENCO).

2

Set your chain offset

Your engineering team already knows the STL → encoder → transmitter delay (typically 2–7 seconds). Punch the value into the dashboard once. Every online listener is now aligned to your over-the-air signal.

3

Embed the aligned player

One script tag on your station site, mobile app SDK, or smart-speaker skill. Every listener on every device hears the same beat as the transmitter. Drive-time scales automatically.

Hear it for yourself

Two browser players, one broadcast. Both hit the same beat at the same instant. At your station, the same engine holds that beat in lockstep with your transmitter — so every listener on FM, DAB+, web, mobile, and smart speakers lands on the same moment.

  2. The players will align to the same moment in the broadcast. It takes about a second.
  3. Open this page on your phone or a second laptop on the same network. Every device lands on the same beat.

Where broadcasters feel the difference

The places where every other streaming stack quietly fails.

FM in the kitchen, app in the bedroom

The household that listens on multiple devices stops hearing the same song twice. One signal, every room, same beat — without proprietary multi-room hardware.

HD2 and web-only subchannels in lockstep

A listener jumping from your main feed to your jazz HD2 or web-only specialty stream lands mid-bar, not mid-buffer. Up to 15 streams per Regional account, all aligned to the same wall clock.

Sports commentary on the right play

A goal call on FM that lands eight seconds later on the web stream loses the moment. Sonotiq keeps commentary, crowd noise, and any in-venue audio feed tied to the same play — across every distribution channel.

Affiliate networks, single source of truth

Station groups syndicating one master feed across owned-and-operated affiliates: every affiliate’s online listeners land on the same instant as the network’s flagship transmitter. One clock, every signal.

Now onboarding reference broadcasters

Be one of the first three on air

We’re working with a small cohort of broadcasters to ship FM-aligned simulcast as a flagship feature of their app and web player. Joining the cohort gets you concessions you won’t see again.

50% off year one

Half-price on whichever tier matches your audience size, locked in for the first 12 months on a 24-month contract.

Hands-on integration support

Our engineering team works directly with yours to wire the player into your existing site, app, and partner embeds — free, however long it takes.

Joint case study + speaking slots

A measured technical case study with your engineering team. Joint conference appearances at Radio TechCon, IBC, and NAB if you’re game.
