Podcast hosting that measures instead of guessing.
Most hosting platforms are a control panel bolted onto a generic encoder. Loudness is whatever it happens to be. Publishing runs on a batch job that catches up eventually. Downloads show up in a report the next day. None of it is engineered — it just works well enough that nobody’s checked.
Castcore is podcast hosting built by broadcast engineers.
We build broadcasting infrastructure that keeps national broadcasters and Finnish crisis communications authorities on air when everything else stops. Castcore applies the same discipline to podcast hosting: every episode measured with R128 methodology, encoded with Fraunhofer AAC, and conformed to the AES77 −18 LUFS target with a −5 dBTP ceiling — the same processing chain a national broadcaster runs, aimed at an RSS feed instead of a transmitter.
Publish on the second, not on the next batch run.
Schedule a release for 06:00 and it goes live at 06:00. There’s no gap between the time you set and the time it’s live, because there’s no nightly batch job standing between them. Analytics work the same way — play confirmations land within seconds, not a next-day report, so you can watch a release climb while the moment still belongs to you.
Every byte stays in the EU.
Audio, metadata, images, and analytics are stored in the EU and kept there — GDPR-friendly by architecture, not a policy checkbox added afterward. The listener data collected (approximate location, device type, platform) is anonymized enough that no single listener could be identified from it.
Move your show in an afternoon.
Point the import tool at any RSS feed. Castcore pulls the back catalogue, re-encodes every episode to spec, and re-hosts it in the EU. Your current host forwards listeners to the new address, apps pick it up on their next refresh, and nobody re-subscribes. Leaving works the same way in reverse — a full export, any time, no lock-in by design.
Your audience is yours.
Castcore’s only revenue is your subscription. No ad network, no listener data sold or aggregated across shows, no incentive to care about your download count beyond wanting you to stay. Standard RSS 2.0 with the iTunes namespace means your audience comes with you wherever you go — that’s not a feature, it’s what the standard is for.
What national broadcasters do. For your podcast.
Same engineering discipline, aimed at an RSS feed instead of a transmitter.
Without Castcore
Guessed loudness. Batch publishing. Aggregated data.
Most hosting platforms are a control panel bolted onto a cheap encoder, publishing on a batch schedule and reporting downloads a day late. You're guessing whether your loudness is right for each platform, and your listener data lives wherever the vendor's servers happen to be.
With Castcore
Conformed to spec. Published on the second. EU by default.
Castcore encodes every episode with Fraunhofer AAC and conforms it to the loudness target each platform actually expects. Publish the second you schedule it — no batch window, no lag. Every byte of audio, metadata, and analytics stays in the EU, and no ad network is reading your download numbers over your shoulder.
Broadcast-grade audio
Every episode is measured with R128 methodology, run through a real dynamics pipeline, and stored at −18 LUFS with a −5 dBTP ceiling under the AES77 standard. National broadcasters build this in-house. Castcore does it because we're those engineers.
Zero-latency publishing
Schedule a release for 06:00 and it goes live at 06:00 — not whenever a nightly batch job gets to it. Your release window is a commitment, not an estimate.
EU data residency, real-time analytics
Audio, metadata, and images stay in the EU by architecture, not a policy footnote. Play confirmations land in seconds, not a next-day report, and the data behind them is anonymized enough that no single listener could be identified from it.

What happens next
Who this is for
Independent podcasters and small networks who want broadcast-grade audio without operating loudness and encoding infrastructure themselves. Anyone leaving a host that batches publishing overnight, aggregates listener data across an ad network, or can’t say which country their audio lives in.
If your current host makes you guess at loudness or wait for downloads to show up, Castcore fixes that.
How it works
Point the import tool at any RSS feed. Castcore pulls the back catalogue, re-encodes every episode to spec, and re-hosts it in the EU — your current host forwards listeners to the new feed, so nobody has to re-subscribe.
Publish through the Castcore web app. Every episode gets Fraunhofer AAC encoding and AES77 loudness conformance automatically. Standard RSS 2.0 with the iTunes namespace means every app and platform your listeners already use keeps working exactly as it did.
