On-device transcription
Record audio on Mac or iPhone, then transcribe it locally using the Apple Speech framework. The product page says transcription runs at high speed, supports multiple languages, and does not require a network connection.
What Signal Recorder SR-7 does
Signal Recorder SR-7 is a native voice recorder for macOS and iPhone that keeps recording, transcription, summaries, and storage on your own devices. It is sold as a one-time purchase, requires macOS 26 or iOS 26, and does not use accounts or a subscription model.
The app is designed for capturing ideas, conversations, and observations, then turning them into searchable text you can review later. Recordings can be transcribed locally, summarized on-device on supported Macs, exported as Markdown, and synced through iCloud when you want the same library on both Mac and iPhone.
Key features
Local AI titles and summaries
Generate descriptive titles and concise summaries locally on macOS 26+ using FoundationModels. This makes recordings easier to skim and search without sending audio to the cloud.
Markdown export
Export each recording automatically as a Markdown file with YAML front matter, so the output can fit into Obsidian, PKM systems, and other Markdown-based workflows.
iCloud sync across Apple devices
Keep recordings, transcripts, and metadata synchronized across Mac and iPhone with iCloud sync via CloudKit. The product also supports a read-only transcript mirror on macOS.
Full-text search
Search names, titles, summaries, and full transcripts from one library. The site says full-text search is built in, so older recordings remain findable by content.
Local AI tool access and audio import
On macOS, connect an MCP-compatible AI tool to search the archive, pull summaries, and extract quotes locally. The product page also notes support for importing audio from hardware recorders such as the TP-7.
Practical use cases
Personal note capture
Capture voice notes, meeting thoughts, and spoken ideas on iPhone or Mac, then turn them into searchable transcripts and summaries without sending audio to a server.
Hardware recorder workflow
Import recordings from the teenage engineering TP-7 or another hardware recorder, then use SR-7 to transcribe, title, summarize, and organize the files in one library.
Cross-device sync
Keep a single archive available on both Mac and iPhone through iCloud, so you can start a recording on one device and review or search it on another.
PKM and writing workflows
Use the Markdown export and read-only transcript mirror to move recordings into Obsidian or another Markdown-based knowledge base.
Local AI-assisted search
On macOS, connect an MCP-compatible AI tool to search recordings, pull summaries, and extract quotes from your archive locally.
