What You Need Before Starting

For Method 1 (Audacity’s Built-In OpenVINO Whisper Plugin)

A current Audacity version installed on your Windows, macOS, or Linux computer (use the version recommended by the OpenVINO plugin release notes; current Audacity releases are in the 3.7.x line)
The OpenVINO AI Plugin for Audacity, downloaded from the official Audacity plugins page at audacityteam.org
A recorded audio track open in Audacity
Sufficient processing power: the medium and large Whisper models require more CPU/GPU resources

A Учетная запись Sonix: the free trial includes 30 minutes of transcription with no credit card required
Knowledge of the language(s) spoken in the recording

Does Audacity Have Built-In Transcription?

Yes. Since the introduction of the OpenVINO AI plugin, Audacity supports on-device transcription powered by OpenAI’s Whisper model. The plugin installs directly into Audacity and adds a new analysis effect called OpenVINO Whisper Transcription under the Analyze menu. Transcription runs entirely on your own computer: no internet connection is needed, no audio leaves your machine, and there are no per-minute charges.

The built-in method writes the transcript to a label track below the audio waveform. Each phrase appears as a time-stamped label that you can edit and export as SRT, VTT, or plain text using File > Export Other > Export Labels.

However, most professionals who need Audacity audio transcription at scale, or who need speaker diarization, 53+ language support, a synchronized editing interface, or export to Word and PDF, use a dedicated automated transcription service alongside Audacity rather than the plugin alone.

Method 1: Free, Offline Transcription (OpenVINO Whisper)

This method runs entirely on your computer. No account, no uploads, no subscription. Best for single speakers, clean audio, and offline environments.

Step 1: Install the OpenVINO AI Plugin for Audacity

Go to the OpenVINO AI Effects for Audacity page on audacityteam.org
Download the installer for your operating system (Windows, macOS, and Linux are all supported)
Run the installer: it places the plugin files in Audacity’s plugins directory automatically
Launch or restart Audacity
Open the Analyze menu: you should now see OpenVINO Whisper Transcription and related AI effects listed

If the menu item doesn’t appear, go to Tools > Plugin Manager, locate the OpenVINO entries, click Enable, and restart Audacity.

Step 2: Reduce Noise Before Transcribing

Whisper performs best on clean audio. Before running transcription, denoise the track:

Select all audio on the track (Ctrl+A or Cmd+A)
Перейти к Effect > OpenVINO Audio Denoising (installed with the plugin pack)
Apply the effect and let it process
Play back a few seconds to confirm the background noise has been reduced

Skipping this step on recordings with significant background noise (fan hum, room reverb, outdoor wind) measurably reduces transcription accuracy.

Step 3: Select Your Audio and Run Whisper Transcription

Select the audio region you want to transcribe: use Ctrl+A to select the entire track, or drag to select a specific segment
Перейти к Analyze > OpenVINO Whisper Transcription
In the dialog that opens, choose your settings:
- Model size: base is fastest for clean English; small or medium handles accents and non-English languages better; large is the most accurate but slowest
- Language: Set this manually, especially for short clips, to prevent Whisper from misdetecting the language
- Initial Prompt (optional): Enter proper names, brand names, or technical terms so Whisper spells them correctly throughout the transcript
- Speaker diarization: Enable this if you need speakers labeled (requires the small.en-tdrz model, which includes experimental diarization)
Нажмите Apply and wait while the model processes the audio

When transcription completes, a new label track titled Транскрипция appears below the audio waveform. Each label contains a phrase from the audio, synchronized to the waveform by timestamp.

Step 4: Export the Transcript from Audacity

Click anywhere in the label track to select it
Перейти к File > Export Other > Export Labels
Choose your format:
- SRT: for video editors and YouTube captions
- WebVTT: for web-based media players
- Plain text (.txt): for documents, notes, and search
Name the file and save it

The exported file contains every phrase with its start and end timestamp, making it ready to drop into a video editor or upload as a caption file.

Sonix is the leading cloud transcription platform trusted by Google, Stanford, and ESPN.

Step 1: Export Your Audacity Recording

If you want to work with a processed, edited version of your recording rather than uploading the raw AU project file, export from Audacity first:

In Audacity, go to File > Export Audio
Choose your format: MP3 (compressed, smaller file) or WAV (uncompressed, largest quality)
Set the quality settings and name the file
Нажмите Экспорт and save to your computer

Alternatively, you can upload Audacity’s native .AU format directly to Sonix without any export step: Sonix accepts AU files alongside all common audio and video formats.

Step 2: Upload Your Audio to Sonix

Go to sonix.ai and sign in (or start your 30-minute free trial: no credit card required)
Нажмите Загрузить on the Sonix dashboard
Select your Audacity audio file from your computer, or import directly from Google Drive or Dropbox if you store recordings there
Sonix accepts MP3, WAV, M4A, AU, FLAC, OGG, AAC, and most other audio and video formats

Step 3: Select Language and Start Transcribing

After uploading, Sonix prompts you to select the язык spoken in the recording
Choose from 53+ supported languages: Sonix automatically handles technical vocabulary, proper nouns, and domain-specific terminology across all of them
Нажмите Start Transcribing

Sonix processes files up to 10x faster. A 60-minute Audacity recording can return a complete transcript in under five minutes, depending on conditions.

Step 4: Review, Edit, and Export

Sonix opens the finished transcript in its synchronized editing interface. Every word is linked to the corresponding audio timestamp: click any word to jump directly to that moment in the recording.

Key features available in the Sonix editor:

AI speaker diarization: Sonix automatically detects speaker changes and labels each speaker’s dialogue throughout the transcript. For a two-person interview, this means every exchange is cleanly separated without manual tagging
Word-level timestamps: every single word carries a millisecond-accurate timestamp, useful for subtitle syncing and legal documentation
In-browser editing: correct any word in the synchronized editor and the change applies across all export formats simultaneously
Search: use Ctrl+F to find any word or phrase instantly within a transcript of any length

To export your finished transcript:

Нажмите на кнопку Экспорт button in the top-right of the editor
Choose your format:
- DOCX or PDF: for reports, documentation, and sharing
- SRT or VTT: for video captions (YouTube, Premiere Pro, Final Cut, DaVinci Resolve)
- Plain text: for note-taking apps, CMS uploads, or AI tools
- 30+ additional formats: including JSON with timestamps, for developers and data pipelines

For solo podcasters, researchers with one-time recordings, or anyone working in a fully air-gapped environment, the built-in OpenVINO method handles the task without any external service. For teams, content workflows, journalism, legal documentation, or any project where speaker labeling and export flexibility matter, Sonix delivers the accuracy and workflow features that raw Audacity label tracks do not offer.

Common Mistakes to Avoid

Not denoising before transcribing. Background noise, even a subtle hum or room reverb, significantly affects transcription accuracy in both methods. Always apply noise reduction in Audacity before exporting or running Whisper. Audacity’s built-in Noise Reduction effect (Effect > Noise Reduction) and the OpenVINO AI Denoising effect both work well; the AI denoising is more effective for recordings with heavy interference.
Uploading a multi-track Audacity project without mixing down. Audacity projects (.AUP3) can contain multiple tracks, including different microphone channels, music beds, and sound effects. Before transcribing, make sure you’re working with a single mixed-down audio file. Use Tracks > Mix > Mix and Render in Audacity before exporting.
Choosing the wrong language setting. In both methods, manually specifying the recording language produces more accurate results than relying on auto-detection, especially for short clips, technical vocabulary, or recordings that start with silence. Always select the language explicitly.
Skipping the speaker diarization step for multi-person recordings. If your Audacity recording contains an interview, panel discussion, or meeting with multiple speakers, using a method without AI speaker diarization produces a single undivided block of text that is hard to read and difficult to attribute. Enable diarization in the Whisper settings or use Sonix, which applies speaker diarization automatically on every transcript.
Exporting in the wrong format for the downstream use case. SRT files are for video captions: don’t paste them into a Word document. Plain text strips timestamps: don’t use it for subtitle imports. Match the export format to the destination: SRT or VTT for video, DOCX or PDF for documentation, TXT for plain-text workflows.

Tips for Better Automatic Transcription Results

Pre-process audio before transcription.

The noise reduction techniques in Audacity, including noise gates, equalization, and compression, directly improve automated transcription accuracy. A 30-second noise profile capture followed by noise reduction and a gentle high-pass filter (to cut low-frequency rumble) is the standard pre-processing workflow for interview recordings. Apply these effects before transcribing with either method.

Use Initial Prompt for brand names and technical terms.

Whisper (via the Initial Prompt field) and Sonix handle proper nouns and technical vocabulary more accurately when given a short context hint. For a product interview, entering the company name, product names, and industry terms as an initial prompt prevents common misspellings in the final transcript.

Set a custom vocabulary for recurring terminology.

If you transcribe Audacity recordings regularly in a specialized domain such as medical, legal, or engineering, Sonix’s custom vocabulary feature lets you define terms that should always be transcribed a specific way, preventing inconsistencies across a large batch of files.

Batch upload for high-volume workflows.

If you record daily Audacity sessions, such as podcast interviews, client calls, or field audio, Sonix supports batch uploads. Drop multiple files at once, and all of them are processed in parallel. Sonix’s API also supports automated upload pipelines for teams that need transcripts delivered to a database or CMS without manual steps.

Leverage timestamps for content repurposing.

Every Sonix transcript includes word-level timestamps. For podcast editors, this means you can search the transcript for a specific quote, note the timestamp, and jump directly to that moment in Audacity to make precise cuts without scrubbing through the entire recording.

Note on translation.

Соникс translation feature converts a completed transcript into 54+ языков directly in the platform. Translation is available and billed separately at the same hourly rate as transcription.

Final Verdict

There is no single best method for every Audacity workflow. Here is how to decide when choosing how to transcribe Audacity recordings automatically:

Для offline transcription of clean, single-speaker recordings, Audacity’s OpenVINO Whisper plugin is the right fit. It is free, fully private, and requires no external service. It handles solo podcast sessions, lecture captures, and any workflow where audio never leaves your machine. The OpenVINO plugin is the only fully local transcription option built into Audacity.
Для multi-speaker recordings, professional output, or high-volume workflows, Sonix is the most complete option. It delivers 99% accurate, AI speaker-labeled, fully formatted transcripts in under five minutes with no label track cleanup, no manual speaker tagging, and export-ready for Word, PDF, YouTube, or your video editor. Manual transcription typically requires 4 to 6 hours per hour of audio; Sonix automates this in minutes, as detailed in Sonix’s transcription resources.
