Cloud DAB & DAB+ Encoder

Professional DAB & DAB+ Encoding in the Cloud

Our Cloud DAB & DAB+ Encoder gives radio stations a complete managed route from studio audio to the digital radio multiplex, without the need to install and maintain dedicated encoding hardware at your premises.

Choose DAB+ with AAC-based encoding or classic DAB with MPEG Layer II, while using the same managed source control, programme processing, metadata, monitoring, alerting and EDI delivery platform.

The service is designed for broadcasters who need more than a basic cloud encoder. Automatic failover and failback, multiple backup sources, emergency audio, broadcast processing, dynamic metadata, DLS, DL+, slideshow, live analysis, detailed monitoring, alerting, operational logs, service reports and multiple multiplex destinations are all managed from one control panel.

How does it work?

There is no specialist encoder hardware for you to install. Your station sends programme audio to autopo.st either by providing an existing live stream URL or by connecting a standard Icecast-compatible source encoder directly to the platform.

Use your existing stream or encode directly to us

If you already operate an internet radio stream, we can use it as your programme source. The platform verifies the stream, detects its audio format and continuously monitors its health.

Alternatively, connect your studio automation or source encoder directly to our platform using standard Icecast-compatible source streaming. This provides a dedicated contribution path without requiring a public listening stream.

Automatic failover that keeps your programme on air

Add multiple backup sources in priority order. If the primary source disconnects, stalls or meets your configured silence conditions, the platform can automatically switch to the next healthy source. When the primary returns and remains stable, it can be returned to service according to your failback policy.

You can also upload emergency audio as the final programme fallback. Authorised users can make another healthy source live from the control panel and later return the service to automatic source selection.

Broadcast audio processing

Programme processing is applied after source selection and before DAB/DAB+ encoding, so the same station sound follows whichever primary, backup or emergency source is currently on air.

Built-in processing can manage programme level, AGC, equalisation, compression, limiting, stereo width and output gain. Processing changes are validated before they are applied, with safe bypass and rollback behaviour designed to protect the programme path if a configuration cannot be activated successfully.

DAB and DAB+ from the same platform

Select the broadcast standard required by your multiplex operator. DAB+ services use AAC-based encoding, while classic DAB services use MPEG Layer II. The platform shows only the settings that are relevant to the selected technology and validates the encoder configuration before applying changes.

Professional EDI delivery to your multiplex

EDI can be delivered to multiple multiplex destinations, allowing primary and secondary mux paths to be configured independently. TCP destination health is monitored in real time, while UDP delivery is clearly identified as unacknowledged rather than being incorrectly shown as connected.

Dynamic metadata, DLS, DL+ and slideshow

Deliver more than just audio. Metadata follows the source that is actually on air, including automatic failover, manual source changes and emergency operation, helping prevent stale programme information being left on the receiver after a source switch.

Artist and title information can be parsed, normalised, transformed and filtered before delivery. DLS and DL+ can be generated from the effective metadata state, while Slideshow (SLS) can display station graphics, programme images and now-playing artwork on compatible receivers.

Artwork can be supplied by the station, mapped to specific content or automatically sourced where configured. Scheduling, programme information, presenter details, promotional messages, manual overrides and artwork rotations can all be managed as part of the metadata workflow.

Live monitoring from input to multiplex

See the health of the complete contribution chain from one dashboard. Monitor the active input source, source-management engine, programme processing, DAB/DAB+ encoder, PAD service, telemetry and every configured EDI output.

Live stereo VU meters show current programme levels, while configurable silence monitoring can raise incidents or trigger input failover according to the policy you choose.

Live broadcast audio analyser

Go beyond simple VU meters with a dedicated analyser view for the programme signal being supplied to the encoder. Detailed visual telemetry helps engineers identify level, loudness, stereo and spectral issues without placing another reader in the critical encoder audio path.

See what your listeners see

Receiver Preview presents the current service through a simulated colour-screen DAB receiver using the effective service, metadata and slideshow state generated by the platform.

View the service name, DLS, DL+, programme information and current SLS artwork together in a receiver-style display, making it easier to check the customer-facing presentation without moving between separate technical status panels.

Receiver Preview is a platform-side visualisation of the current generated service state; independent off-air receiver verification remains a separate engineering test.

Alerts that reach the right people

Create contacts and contact groups, then decide exactly which conditions should reach which people. Alerts can be routed by email, SMS, automated voice call, generic webhook, Slack, Microsoft Teams or PagerDuty.

Escalation rules, trigger delays, recovery notifications, maintenance windows, acknowledgement and incident deduplication help avoid alert storms while still making sure genuine problems reach the right person.

Detailed logs and scheduled reports

Search structured operational and audit logs by time, component, category and severity, or follow events as they happen. Important configuration changes and manual actions are recorded alongside technical incidents so you can see exactly what happened and when.

Weekly, monthly and on-demand HTML reports provide human-readable availability and service information for the programme input, encoder, PAD and EDI outputs, together with incident, failover and alert summaries. Reports can be scheduled and emailed automatically to selected recipients.

Built for service continuity

The platform separates source management, programme processing, encoding, PAD and monitoring so that one component can be restarted or recovered without unnecessarily restarting the complete service. Where technically possible, source and configuration changes are applied only to the component that actually needs to change.

If a programme source fails, the service can move through configured backups and emergency audio while the DAB/DAB+ encoder remains available. Failed configuration changes are validated and rolled back where possible instead of leaving the service in a broken state.

Why use autopo.st Cloud DAB & DAB+ Encoder?

A basic hosted encoder converts an audio stream into DAB or DAB+ and sends it to a multiplex. autopo.st manages the wider broadcast contribution chain around that encoder: source continuity, programme processing, metadata and artwork, EDI delivery, monitoring, alerting, analysis, audit history and reporting.

What information does my multiplex operator need?

Your control panel clearly shows the parameters that need to match at the multiplex, including the selected DAB/DAB+ standard, output bitrate, codec or effective profile, channel mode where applicable and EDI destination information. The system does not pretend to configure the remote multiplex itself; it gives you the information required to coordinate the service correctly with your multiplex operator.
