Fieldwork Recorder vs Sound Scope Analyzer

Record interviews and field observations. Preserve the context that makes them useful. Fieldwork Recorder is a private, local-first recorder and journal for research, interviews, and field observations. Keep audio, notes, photos, sketches, tags, time, and place together in one entry. RECORD WITH CONFIDENCE • Choose high, medium, low, or custom audio quality. • Continue recording in the background when your device allows it. • Follow live recording status and clear saving progress during long sessions. CAPTURE THE WHOLE CONTEXT • Add a title, tags, formatted notes, photos, and hand-drawn sketches. • Use the simple formatting toolbar, or write directly in Markdown if you prefer. • Save no location, start and end positions, or a complete GPS track. • Browse entries on a calendar, search by title or notes, and filter by tag. LISTEN, MAP, AND SHAPE THE STORY • Play recordings with a responsive waveform, precise seeking, playback-speed controls, and file-size details. • Follow GPS-tracked recordings on the map as the audio plays. • Trim unwanted audio, remove a selection, extract a clip, or split a recording into separate diary entries. • Keep the original recording or save the edited result as a copy. BACK UP ON YOUR TERMS • Export a single entry or your entire diary as an archive. • Optionally sync with iCloud, Dropbox, OneDrive, Google Drive, Box, or WebDAV. • Use widgets for Quick Record, Open Last Entry, and Today's Recordings.

Your diary leaves the device only when you choose to export it or connect a cloud provider. No Fieldwork Recorder account is required.
