Transcription Audio

Transcription Audio(Beta) Plugin for Obsidian

Turn your audio into structured Markdown notes inside Obsidian. This plugin detects an audio file linked in your current note, sends it to Gemini for transcription and summarization, and inserts the result back into your note. A right-hand progress panel shows what’s happening step by step.

Features

• Smart audio detection from links or embeds in the active note
• Google Gemini transcription and summarization
• Progress panel (sidebar) with live status:
  • Detected audio filename and size
  • Audio preparation status
  • API request start/completion times
  • Gemini usage logs (prompt/output/total tokens)
  • Cancel button to stop upload/API request in progress
  • Success/error result
• Writes the final output to the file and cursor position where you started the command

Requirements

• A Google AI API key for Gemini. You can obtain one at https://aistudio.google.com/api-keys

Getting started

1. Open Obsidian Settings
2. Navigate to "Community plugins" and click "Browse"
3. Search for "Transcription Audio" and click Install
4. Enable the plugin in Community plugins
5. Set up your API key in plugin settings (SecretStorage recommended)

Configuration

Open Settings → Transcription Audio:

• API Key (SecretStorage, recommended): Select the secret name from Obsidian SecretStorage
• API Key (deprecated, not recommended): Legacy plain-text API key field kept for backward compatibility fallback
• On older Obsidian versions, SecretStorage is disabled and you will see an update-required message (Obsidian 1.11.4+)
• Transcription mode:
  • Basic mode (default): prompt only
  • Template mode: dedicated prompt + output template (both prefilled with defaults)
• Model: Select a Gemini-compatible model (gemini-2.5-flash, gemini-2.5-pro, gemini-3-flash-preview, gemini-3.1-pro-preview)
• gemini-3-pro-preview is deprecated by Google and shuts down on March 9, 2026. Existing settings are automatically migrated to gemini-3.1-pro-preview.
• Prompt: Customize the instruction for the selected mode
• Output template: Available in template mode to enforce a consistent final markdown structure

Usage

1. In a note, linked file before your cursor, for example:
   • Wiki link: ![[example_audio.wav]]
2. Place the cursor after the link.
3. Run the command: "Transcribe audio".
4. A progress panel will automatically open in the right sidebar, showing real-time status updates including file upload progress, API request status, and transcription progress.
5. When complete, the transcription and notes are inserted at your starting cursor position.

Privacy & Data

Audio content is sent to Google’s Gemini API for processing. The plugin does not store your audio or transcripts outside your vault. Keep your API key secure and review your organization’s data policies before use.
