Why This Exists

Own your studio.
Own your tape.

private by default

Silo Systems builds infrastructure for people who would rather not negotiate with their own software. SiloCast is the same discipline, pointed at one job: turning a room full of microphones into a finished, published episode, done entirely on the machine you already own. Your unreleased show never becomes someone else's training data, and your back catalogue never lives on someone else's server.

Offline by default

No upload step. None.

Recording, transcription, transcript review, and supported show-note generation run on your Mac with Apple frameworks. There is no episode upload or hosted inference queue; the studio works offline with the same files you recorded locally.

Privacy-preserving

Your show never leaves the room.

No analytics SDK, telemetry, account, hosted API, or cloud processing. The audio you record, the transcript, timeline markers, generated copy, and exports stay in the App Sandbox or the folder you choose.

Intelligence, on-device

A marketing pack that stays private.

Show notes and transcript-linked chapters are prepared locally through Apple Foundation Models when available, with an honest local fallback. The result remains editable and exportable without sending an unreleased episode to a cloud service.

Three Moves

Record. Verify. Publish.

Record

Every mic, on its
own track.

SiloCast records each USB or XLR microphone and the system audio loopback simultaneously through Core Audio, each captured to its own track. Whoever is in the room and whoever is on the call land in the same session. No virtual cable, no second recorder, no bot joining your show.

every mic, its own track
Transcribe

A local timeline
you can inspect.

Apple Speech turns the recorded session into a timestamped transcript on your Mac. The transcript stays tied to the episode timeline, so a chapter can lead back to the nearest spoken line before you include it in a release bundle.

transcribe, then verify
Publish

Verify the text,
ship the pack.

Correct speakers or wording while keeping the source audio unchanged. In version 1.2.0, one publish action writes processed audio, reviewed chapters, SRT and VTT captions, show notes, a checklist, and a SHA-256 receipt to the folder you choose. Nothing is uploaded or published for you.

One session, end to end.

Multi-track capture.

Record selected USB, XLR, or Core Audio input devices at the same time, with one local track per selected device. Multi-channel interfaces are downmixed into that device track.

USB, XLR, loopback

Source-preserving transcript edits.

Correct a speaker label or wording in the timestamped transcript and save that local text revision. Transcript edits do not alter, cut, or replace the recorded source audio.
