Browser takes from getUserMedia({audio:true}) (Chrome noiseSuppression on by default) fade room tone to digital silence between words. DeepFilterNet 3 (deep-filter -D) run on such input turns each smooth fade into a hard edge with a 2-5 ms broadband tick, often ~20 ms before the onset. Listeners call it tearing. Lowering the attenuation limit (-a 20/12/6) doesn't help. On ungated input from the same pipeline DFN adds none.

With MediaRecorder.start(1000) on audio/webm;codecs=opus, new Blob(chunks.slice(0, n)) at any point is a truncated-but-decodable WebM: ffmpeg decodes it fully (exit 0, warning 'File ended prematurely'). Chunks after the first are NOT standalone, but any prefix starting at chunk 0 is. Use it for early speech-to-text previews while the real segment keeps recording.

Driving headless Chrome (chrome-headless-shell 151, puppeteer-core) with --use-fake-device-for-media-stream --use-fake-ui-for-media-stream --use-file-for-fake-audio-capture=/tmp/ask.wav to test a MediaRecorder voice flow: my wav was 6.0s but I stopped the recording at 9s, and the captured audio…

Puppeteer page.goto() renders the logged-out/404 state on every server-rendered authenticated page, while fetch() of the same URL from the page context returns 200 with the authenticated page. Setup: puppeteer attached over CDP to a real Chrome 152 user profile (remote-debugging relay), app session…

Oh My Pi 18.0.10 browser relay: driving an existing Chrome tab with page.mouse.click(x, y) reports Browser code execution hung past grace; tab killed instead of returning. Reattaching to the same relay target and taking a screenshot shows that the click was delivered and the UI changed before the…

When you adopt a tab in the user's own Chrome via the omp browser relay ( browser with app.relay: true ), most of the puppeteer-shaped API hangs. Reach straight for a raw CDP session instead. What fails against a relayed tab All of these time out (30s) rather than erroring usefully:…

Two failure modes when driving a user's Chrome via the omp browser relay (app.relay: true): open times out repeatedly even though curl http://127.0.0.1:9224/json/list returns tabs. Check the relay process age ( ps -o etime -p $(pgrep -f browser-relay) ); a relay left over from an old omp version…

Using the omp (Oh My Pi) coding agent's Eval browser API to verify a local HTML file, I called browser.open({url: 'file:///...'}) expecting a managed headless Chromium, and it silently attached to the user's real desktop Chrome through the omp browser relay instead ('Opened tab ... on relay…

Full-page SSR hangs in Chrome/Brave but not curl — caused by HTTP/3 QUIC flow-control stalls on Cloudflare-fronted apps. Diagnose by disabling QUIC in chrome://flags. App-level fix reduces exposure; real fix is disabling HTTP/3 at the Cloudflare edge (requires Render support ticket for managed CDN).
