What is Signal Recorder SR-7?

Signal Recorder SR-7 is a voice recording app for Mac and iPhone from Field Bureau and Werkstatt. It records audio and then transcribes, titles and summarises it entirely on the device, exporting each recording as a markdown file with YAML front matter. There are no accounts, no telemetry and no cloud processing, and it works offline. It is sold as a one-time purchase rather than a subscription.

Key Features

On-device transcription

Converts speech to text locally using the Apple Speech framework, with no audio sent to the cloud.

AI titles and summaries

Generates a title and summary for each recording using Apple FoundationModels on supported hardware.

Markdown export

Saves each recording as a markdown file with YAML front matter for use in other tools.

MCP server

Exposes recordings to AI tools through a built-in Model Context Protocol server.

iCloud sync

Keeps recordings and transcripts in sync across the user's Apple devices.

Full-text search

Searches across transcripts and metadata to find past recordings.

External recorder support

Works alongside dedicated audio recorders such as the TP-7 and supports multiple languages.

Pros & Cons

Advantages

  • The one-time price of $7.99 avoids any recurring subscription cost.
  • All transcription and summarisation runs on the device, with no accounts, telemetry or cloud processing.
  • Markdown export with YAML front matter fits neatly into note-taking and knowledge-management workflows.
  • iCloud sync and full-text search make recordings easy to keep and find across Apple devices.
  • The built-in MCP server lets AI tools read recordings directly without extra integration work.

Limitations

  • It is limited to the Apple ecosystem, with no Windows, Android or web version.
  • AI features require recent operating systems and Apple Silicon, so older devices miss out.
  • It depends on iCloud for cross-device sync, which may not suit those outside Apple's services.

Use Cases

Journalists and researchers who record interviews and want an instant on-device transcript.

Writers and note-takers who capture spoken ideas and file them as markdown notes.

Privacy-conscious users who need transcription without sending audio to a cloud service.

Knowledge workers who feed recordings to AI tools through the built-in MCP server.

People who record on a dedicated device such as the TP-7 and want the audio transcribed afterwards.
