Sonicribe System Audio Capture: Transcribe Meetings & Videos

Transcribe Anything Playing on Your Mac

System audio capture is one of Sonicribe's most versatile features. Instead of recording from your microphone, it captures whatever audio is playing through your Mac's audio system. This means you can transcribe Zoom meetings, YouTube videos, podcast episodes, online lectures, webinars, and any other audio source without needing a separate recording tool.

The entire process happens locally. The captured audio is processed by Whisper AI on your Mac. Nothing is uploaded to a server. Nothing leaves your device.

What Is System Audio Capture?

Every sound that plays through your Mac's speakers or headphones passes through macOS's audio system. System audio capture intercepts this audio stream and feeds it directly to Sonicribe's transcription engine.

The audio source does not matter. If it makes sound on your Mac, Sonicribe can transcribe it:

• Video calls: Zoom, Google Meet, Microsoft Teams, WebEx, FaceTime
• Video content: YouTube, Vimeo, Netflix, streaming platforms
• Audio content: Podcasts, Spotify, Apple Music (spoken word), audiobooks
• Online lectures: Coursera, Udemy, university portals, live streams
• Webinars: Any browser-based or app-based webinar
• Recorded files: Any audio or video file playing in a media player

How to Set Up System Audio Capture

Step 1: Grant Audio Permissions

Sonicribe needs macOS permissions to capture system audio. On first use:

1. Open System Settings on your Mac

2. Navigate to Privacy & Security

3. Find Screen Recording (or Audio Recording, depending on macOS version)

4. Enable Sonicribe in the list

5. Restart Sonicribe if prompted

This is a one-time setup. macOS requires these permissions to prevent unauthorized apps from recording your screen or audio.

Step 2: Switch to System Audio Input

In Sonicribe's input settings, you will see options for your audio input source:

• Microphone: Captures audio from your built-in or external microphone (default)
• System Audio: Captures audio playing through your Mac's audio system

Select "System Audio" to switch to system audio capture mode.

Step 3: Start Playing Your Audio Source

Open the application that will produce the audio you want to transcribe:

• Join a Zoom meeting
• Open a YouTube video
• Start a podcast episode
• Play an audio file

Make sure the audio is playing through your Mac (not through a separate Bluetooth speaker or external device, unless your Mac is routing audio to that device).

Step 4: Start Recording in Sonicribe

Once your audio source is playing, start recording in Sonicribe. The system audio will be captured and queued for transcription.

Step 5: Stop Recording and Review

When your audio source ends (or when you want to stop capturing), stop the recording in Sonicribe. The captured audio will be transcribed using your selected Whisper model, and the transcript will appear for review.

Use Case 1: Transcribing Video Meetings

System audio capture is the privacy-conscious way to transcribe video meetings. Unlike Otter.ai or Fireflies, which join your meeting as a visible bot and process audio on their cloud servers, Sonicribe captures the meeting audio silently on your Mac and transcribes it locally.

The Meeting Transcription Workflow

1. Open Sonicribe and switch to system audio capture

2. Join your Zoom, Meet, or Teams meeting

3. Start recording in Sonicribe

4. Attend the meeting normally

5. Stop recording when the meeting ends

6. Review the transcript

Tips for Meeting Transcription

Use headphones. When you listen through speakers, the microphone (even though you are using system audio capture) can create feedback issues on some setups. Headphones ensure clean audio capture. Enable speaker identification. For multi-person meetings, turn on speaker identification to label who said what. This transforms a monolithic transcript into a readable conversation. Use the appropriate vocabulary pack. If your meeting involves technical, medical, legal, or business terminology, enable the relevant vocabulary pack before recording. Capture the full meeting. Start recording before the meeting begins and stop after it ends. It is easier to trim extra content from a transcript than to miss the beginning or end of an important discussion.

Privacy Advantages over Meeting Bots

Use Case 2: Transcribing YouTube and Online Videos

Researchers, students, and content creators often need transcripts of online videos. System audio capture lets you transcribe any video playing in your browser.

The Video Transcription Workflow

1. Switch Sonicribe to system audio capture

2. Open the video in your browser (YouTube, Vimeo, etc.)

3. Start recording in Sonicribe

4. Play the video at normal speed

5. Stop recording when the video ends

6. Review and export the transcript

Speed Considerations

For the best accuracy, play videos at normal speed (1x). Playing at 1.5x or 2x speed reduces transcription accuracy because the audio is compressed and speech patterns are distorted.

If you need to transcribe a long video quickly, record it at normal speed and let Sonicribe's Whisper model process it. A one-hour video produces a transcript in approximately 5 minutes of processing time on an M3 Mac, regardless of how long the recording took.

YouTube vs Downloaded Files

If you have the option to download the video file (from a platform that allows it), importing the file directly into Sonicribe is faster and produces slightly better quality than system audio capture. System audio capture introduces one additional stage of audio processing. For most content, the quality difference is negligible. For content with background music or poor audio quality, direct file import can make a noticeable difference.

Use Case 3: Transcribing Podcasts and Audio Content

Podcast transcription is valuable for researchers, journalists, and anyone who wants to search spoken content. System audio capture lets you transcribe any podcast playing on your Mac.

The Podcast Workflow

1. Switch to system audio capture

2. Open your podcast player (Apple Podcasts, Spotify, Overcast, or browser)

3. Start recording in Sonicribe

4. Play the podcast episode

5. Stop recording and review

Batch Podcast Transcription

For transcribing multiple episodes, consider downloading the podcast files (most podcast apps support this) and importing them directly into Sonicribe. This lets you queue multiple files for batch processing rather than recording each one in real time.

Use Case 4: Transcribing Online Lectures and Courses

Students and professionals taking online courses can transcribe lectures for study purposes.

The Lecture Workflow

1. Switch to system audio capture

2. Open the online lecture in your browser or course app

3. Start recording in Sonicribe

4. Watch the lecture at normal speed

5. Stop recording and review

6. Save the transcript alongside your notes

Study Tips for Lecture Transcripts

• Search for key terms: Text transcripts let you search for specific concepts discussed in the lecture
• Create summaries: Use the transcript as raw material for condensed study notes
• Cross-reference: Compare the transcript with your handwritten notes to fill in gaps
• Export as Markdown: Save transcripts as Markdown files in Obsidian or similar note-taking apps for linking and searching

Use Case 5: Transcribing Webinars and Live Streams

Webinars and live streams cannot be paused and replayed like recorded content. System audio capture lets you create a transcript in real time.

The Live Stream Workflow

1. Switch to system audio capture

2. Open the webinar or live stream

3. Start recording in Sonicribe when the content begins

4. The audio is captured as the event progresses

5. Stop recording when the event ends

6. Review the complete transcript

This is particularly valuable for live events where no recording will be made available afterward.

Advanced: Combining Microphone and System Audio

In some scenarios, you want to capture both system audio (other participants' voices) and your own microphone input (your voice). This is useful for transcribing meetings where you are an active participant and want your contributions included in the transcript.

Sonicribe supports this combined capture mode. When enabled, it records both the system audio output and your microphone input, merging them into a single audio stream for transcription.

When to Use Combined Capture

• You are presenting in a meeting and want your narration plus audience questions transcribed
• You are participating in a discussion and want the complete conversation, including your own contributions
• You are recording a call where both sides of the conversation should be captured

When to Use System Audio Only

• You are a passive listener (no need to capture your own voice)
• You are transcribing pre-recorded content
• You want to avoid capturing ambient noise from your microphone

Troubleshooting System Audio Capture

No Audio is Being Captured

• Verify Sonicribe has Screen Recording or Audio Recording permissions in macOS System Settings
• Restart Sonicribe after granting permissions
• Check that audio is actually playing through your Mac (not muted, not routed to an external device)
• Ensure you selected "System Audio" as the input source in Sonicribe

Audio Quality Is Poor

• Check that the source audio is playing at reasonable volume (not too quiet)
• Close other applications that might be producing competing audio
• For video calls, ensure the call's audio quality settings are maximized

Transcript Has Gaps

• System audio capture can miss audio during brief macOS audio routing changes (e.g., connecting/disconnecting headphones during recording)
• Keep your audio routing consistent during the recording session
• For critical recordings, avoid changing audio output devices mid-session

Permission Issues After macOS Update

macOS updates sometimes reset privacy permissions. If system audio capture stops working after a macOS update:

1. Open System Settings > Privacy & Security

2. Remove Sonicribe from the permission list

3. Re-add Sonicribe

4. Restart the application

Start Capturing System Audio

System audio capture transforms Sonicribe from a dictation tool into a universal transcription tool. Anything that plays on your Mac can be transcribed locally, privately, and accurately.

Download Sonicribe and try system audio capture with your next meeting, video, or podcast. The free tier gives you 5,000 words per week. Switch to system audio input, press record, and let Sonicribe transcribe whatever you are listening to.
