Listen, annotate, connect
Audio Lab
Listen to the example recordings, search them by sound and keep notes on the passages you find. The same page connects to a Tierline server running on your own computer, which checks permissions for every request. To add your own files in the browser, use the Workspace.
Listen and take notes
Listen, search and keep notes on passages
Play a recording, select a short passage, and search for passages that sound like it. Notes stay attached to the exact span of audio they describe.
Connect to your own workspace
Open this page from Tierline's loopback server on your own computer, then enter the token it printed at startup. This public website cannot reach a private archive.
Identity, role and purpose are configured by the operator when the server starts. The token is held in memory only, never in browser storage. The server — not this page — decides what is permitted.

Retrieval processing
Review a cryptographically frozen local recipe before running XLS-R feature extraction and publishing the exact + approximate FAISS pair. Existing verified checkpoints are reused after interruption.
Local archive health
Software-observable readiness from the live local workspace. Recovery-authority verification remains in stewardship-doctor; this browser never receives those keys.
Rule-based checks only. Each item names the check that ran. A receipt records this observation, not continuing safety or a verified recovery.
No detailed check receipt has been requested.
Consent impact and revocation
Review the exact linked records before revoking live consent. This does not purge files, write an external recovery tombstone, or recall delivered copies.
No consent impact has been reviewed.

Acoustic matches
Create authorized EAF/TextGrid files inside the managed workspace first. Downloading a file is a separate, explicit external copy.

What runs on this page, and what runs on a Tierline server
In your browser
What runs on this page. 24-band normalized log-mel features and subsequence DTW, computed in a Web Worker. It is deliberately small so it works on a static site with no server and no upload, for the example recordings here and for your own recordings in the Workspace.
Local retrieval engine
XLS-R layer-11 features, PCA-256, calibrated int8 storage, policy-partitioned FAISS retrieval and subsequence DTW reranking, running locally against an authorized archive (How it works).
Its measured results are on Evaluation.
