[ 001 ] -- For sessions that can't be redone
Never lose a second.
CraterSync records remote podcasts, audiobook narration and voiceover. Every voice is captured at full quality on the device it's spoken into and uploaded while you're still talking, so you get a clean, separate 32-bit track for each person. If the network dies mid-take, the take survives.

One session, start to finish.
A host in Chicago. A guest in Lisbon on hotel Wi-Fi. An interview that only happens once.
SCENE / THE SESSION
The host sends a link. The guest clicks it -- no account, no install -- checks their mic and camera in the browser, and they're talking. Each voice records at 48kHz on its own machine, not from the call.
SCENE / THE DROP
Twenty minutes in, the hotel Wi-Fi dies. The recording doesn't notice. It never depended on the network: the pieces wait on the guest's laptop and upload the moment the connection returns. The call hiccups; the recording never does.
SCENE / THE EDIT
The session ends and each person is a separate track: 32-bit float, 24-bit WAV and FLAC, with the markers you dropped along the way. Nothing to sync, nothing mixed down -- open the stems and start cutting.
Narrating a book or directing a voice actor runs on the same engine: the script sits on the talent's screen and updates live, and takes are marked and circled as they land.
[ 003 ] -- The recording system
Six things every session does.
CraterSync is built around a single idea: the recording on disk is the product, not the feed in the browser. Everything else follows.
Local-first capture
Every participant records at source quality on their own device. Recording quality is decoupled from call quality -- your masters are never compressed to fit the network.
Progressive upload
Chunks travel to the cloud while you're still recording. By the time you stop, most of the session is already safely ingested. No multi-hour waits.
Separate tracks
Each voice on its own stem. Each camera on its own track. Edit with the same freedom a studio engineer expects -- no mixed-down surprises.
Session recovery
Network drops pause uploads, not recordings. Chunks are persisted locally and resume automatically the moment connectivity returns.
Per-session encryption
Every session gets its own 256-bit DEK. Chunks are sealed with AES-GCM before hitting storage. Retention ends with a cryptographic erase, not a support ticket.
One-link guest join
Send a link. Guests walk through a device check in their browser -- no account, no install. Hosts see permissions, bandwidth, and health at a glance.

Nothing is published. There are no public download links and no feeds -- the stems live in your account until you take them.
Deletion is real
Each session is sealed with its own key. When retention ends, the key is destroyed and the files become unreadable -- not just hidden.
Nothing for guests to set up
Guests click a link and check their mic and camera in the browser. No account, no install, no password. You sign in with an emailed code.
