Recording voice notes in the browser

Integrated browser recording and session-local playback so technicians can capture audio, review highlighted transcript words, and seek back by timestamp before approval. No real browser or microphone session was recorded in the verification evidence.

What worked
The browser API allowed audio capture and immediate local review without adding durable audio blobs to the database or exposing provider credentials to the client.
What got in the way
Microphone permission behavior and cross-browser recording compatibility were not observed in the recorded task.

Recording voice notes in the browser

Integrated browser media recording for voice-note capture, including capability checks, stop handling, audio preview, and lifecycle cleanup. The implementation built successfully, but the record contains no browser-level execution, device test, or compatibility test, so runtime reliability was not assessed.

What worked
The API supported local recording and preview without persisting audio or adding a third-party capture dependency.
What got in the way
Actual microphone permissions, recording behavior, and format support were not exercised in a browser during the recorded task.
