How to Split Recorded Meetings for Meeting Notes & Summaries

Recording meetings has become standard practice in remote work environments. Whether you're using Zoom, Microsoft Teams, Google Meet, or Webex, splitting long meeting recordings into manageable segments makes it significantly easier to create meeting notes, transcribe discussions, and extract action items. This guide shows you how to efficiently split meeting recordings for better productivity.

Why Split Meeting Recordings?

Long meeting recordings present several challenges. A 2-hour all-hands meeting or board presentation becomes difficult to navigate, transcribe, or reference later. By splitting recordings into topic-based or time-based segments, you gain significant advantages:

  • Easier transcription - AI transcription services work better with shorter files
  • Topic-based organization - Match segments to agenda items for quick reference
  • Faster review - Jump directly to relevant discussions without scrubbing
  • Better sharing - Send only relevant portions to team members
  • Improved accuracy - Shorter segments produce more accurate AI summaries
  • Storage efficiency - Archive only important segments, delete filler

Meeting Privacy Matters

Meeting recordings often contain confidential business information, strategic discussions, or sensitive personnel matters. ChunkAudio processes all audio entirely in your browser—your meeting recordings are never uploaded to external servers. This ensures complete privacy and compliance with corporate security policies.

Meeting Recording Formats by Platform

Different video conferencing platforms save recordings in different formats. Here's how to get your meeting audio ready for splitting:

Zoom

Zoom creates both video (MP4) and separate audio (M4A) files for local recordings. For cloud recordings, download the audio-only version from your Zoom account. M4A files work directly with ChunkAudio—no conversion needed.

Microsoft Teams

Teams recordings are saved to OneDrive or SharePoint as MP4 files. Download the MP4, then use a free tool like VLC or online converter to extract the audio as MP3. ChunkAudio will then split the audio file for you.

Google Meet

Meet recordings are saved to Google Drive as MP4 files. Download and extract audio using your preferred method. For G Suite Enterprise users, audio-only recordings may be available directly.

Webex

Webex saves recordings as ARF or MP4. For ARF files, use the Webex Network Recording Player to convert to MP4 first. Then extract audio and upload to ChunkAudio.

Step-by-Step: Split Meeting Recordings with ChunkAudio

1Export Your Meeting Recording

Download the meeting recording from your video conferencing platform. If you have a video file, extract the audio track using VLC (Media - Convert/Save - Audio codec only) or an online converter. Save as MP3, M4A, or WAV.

2Upload to ChunkAudio

Visit ChunkAudio.com and drag your meeting audio file onto the upload area, or click to browse. Files are processed locally in your browser for complete privacy.

3Choose Your Splitting Strategy

Select how you want to divide the meeting:

  • By time duration - Create segments of specific length (e.g., 15-minute chunks)
  • By segment count - Divide into a specific number of equal parts
  • By file size - Useful if your transcription service has file size limits

4Configure for Your Workflow

Set the segment duration based on your intended use. See the table below for recommended settings based on different meeting workflow needs.

5Download and Organize

Click Split to process the file. Download individual segments or all at once as a ZIP file. Rename files according to agenda topics for easy reference (e.g., "Q4-Review-Budget-Discussion.mp3").

Recommended Segment Lengths by Use Case

Use Case Recommended Length Why

Splitting for AI Transcription Services

AI transcription services like Otter.ai, Rev, Trint, and Descript have file size or duration limits. More importantly, they perform better with shorter, focused audio segments:

Why Shorter Segments Improve Transcription

  • Speaker identification - AI better tracks who's speaking in shorter segments
  • Context maintenance - Less drift in understanding technical terms
  • Error recovery - If one segment has issues, others remain accurate
  • Parallel processing - Upload multiple segments simultaneously for faster results

Pro Tip: Keep a timestamp log during meetings noting when each agenda item starts. This makes it easy to create segments that align perfectly with discussion topics.

Optimal Settings for Popular Services

  • Otter.ai - 90 minutes max, but 15-minute segments produce better results
  • Rev - No hard limit, but recommends under 3 hours; split for better accuracy
  • Trint - Best results with files under 30 minutes
  • Descript - Handles long files but processes faster in segments
  • WhisperAI (local) - 30-minute segments work well for most systems

Splitting for AI Summarization

Using ChatGPT, Claude, or other AI tools to summarize meetings? The transcription needs to fit within context limits. Here's the approach:

  1. Split meeting into 15-20 minute segments
  2. Transcribe each segment separately
  3. Summarize each segment individually - This produces focused summaries
  4. Combine summaries - Create a master summary from segment summaries

This approach works better than transcribing a 2-hour meeting and trying to summarize it all at once. The AI maintains better context and produces more actionable summaries.

Organizing Split Meeting Files

Effective file organization is crucial when you're splitting many meetings. Here's a recommended naming convention:

[Date]_[Meeting Type]_[Topic]_[Segment#].mp3

Examples:

  • 2026-01-10_StandUp_Sprint-Review_01.mp3
  • 2026-01-10_StandUp_Sprint-Review_02.mp3
  • 2026-01-10_AllHands_Q4-Results_01.mp3
  • 2026-01-10_AllHands_CEO-Update_02.mp3

Privacy and Compliance Considerations

Meeting recordings often contain sensitive information. When choosing tools to process them:

Data Handling Checklist

  • Browser-based processing - Files never leave your device
  • No account required - Reduces data exposure
  • HTTPS encryption - Secure if upload is needed
  • Clear privacy policy - Understand how data is used
  • Corporate policy compliance - Check with IT/Legal if unsure

ChunkAudio meets all these criteria—your meeting audio is processed entirely in your browser and never uploaded to any server. This makes it safe for even the most confidential business recordings.

Common Meeting Types and Splitting Strategies

All-Hands / Town Hall Meetings

Usually long (1-2 hours) with multiple presenters. Split by presenter or topic section. Create separate segments for CEO update, department reports, Q&A, etc.

Sprint Retrospectives

Split into three segments: What went well, What could improve, Action items. This makes it easy to reference specific discussion areas later.

Client Calls

Split into Discovery, Solution Discussion, Next Steps. Keep segments that contain commitments or requirements for easy reference.

Board Meetings

Split by agenda item—financial review, strategic initiatives, governance, etc. Name segments clearly for compliance and archival purposes.

Training Sessions

Split into module-length segments (10-15 minutes). This creates reusable training materials from recorded sessions.

Process Meeting Recordings Privately

Split your meeting recordings by topic or time—entirely in your browser. No uploads, no accounts, complete privacy for sensitive business discussions.

Frequently Asked Questions

How do I split a Zoom recording into segments?
First, download your Zoom recording as an MP3 or M4A file from Zoom cloud or your local recordings folder. Then upload to ChunkAudio and choose your preferred splitting method—either by time intervals matching your agenda or by equal segments for transcription. The tool will create separate files for each segment that you can download individually or as a ZIP file.
What's the best segment length for meeting transcription?
For AI transcription services, 10-15 minute segments work best. This keeps file sizes manageable, improves transcription accuracy by helping the AI maintain context, and makes it easier to review and correct specific portions. For manual note-taking, match segments to your agenda items—typically 15-30 minutes each.
Can I split Microsoft Teams meeting recordings?
Yes! Download your Teams recording from Microsoft Stream or OneDrive (it saves as an MP4 file). Use VLC or an online converter to extract the audio as MP3. Then upload the audio file to ChunkAudio and split it into segments by time or count. The audio-only approach keeps file sizes smaller and processing faster.
How do I extract specific agenda items from a meeting recording?
The best approach is to note timestamps during the meeting or create a timestamp log afterward while reviewing. Then calculate segment durations that align with your agenda items. Use ChunkAudio's time-based splitting to create segments that match these boundaries. Name each downloaded segment according to its topic for easy reference.
Is my meeting recording private when using online splitters?
It depends on the tool. ChunkAudio processes all audio entirely in your browser—your meeting recordings are never uploaded to any server. This ensures complete privacy for confidential business discussions and complies with most corporate security policies. Always check a tool's privacy policy before uploading sensitive recordings.
How can I speed up meeting note creation with split recordings?
Split your meeting into agenda-aligned segments, then transcribe each segment separately using an AI service. Feed each transcript to ChatGPT or Claude asking for key points and action items. This produces more focused summaries than processing the entire meeting at once. You can then compile the individual summaries into comprehensive meeting notes.
