Why Zoom Recording Settings Matter for Transcription

Zoom's default recording settings prioritize video quality and file size over audio fidelity, which can compromise transcription accuracy.

Impact on transcription:

• Poor audio quality: 10-20% reduction in AI transcription accuracy
• Compressed audio: Loses frequency information needed for speech recognition
• Mixed speaker tracks: AI struggles to separate speakers for identification
• Background noise: Interferes with speech recognition algorithms

What improves with optimized settings:

• Clearer audio separation between speakers
• Better preservation of speech frequencies
• Reduced background noise interference
• Proper audio levels without clipping

According to Interspeech 2023 research:

• Professional AI transcription (WhisperX): 88-93% on clean benchmark audio
• Same AI on poor-quality audio: Can drop to 70-80%
• Optimized recording settings: 10-15% improvement possible

For comprehensive Zoom transcription guidance, see Zoom Meeting Transcription: Complete Guide.

Setting 1: Record Separate Audio for Each Participant

Most important setting for multi-speaker transcription accuracy.

What This Setting Does

Records individual audio tracks for each meeting participant instead of mixing all audio into single track.

Technical details:

• Each participant gets dedicated audio file
• Files stored together with master mixed file
• AI transcription services use separate tracks for better speaker identification
• Significantly improves multi-speaker transcription accuracy

Benefit for transcription:

• AI can identify speakers more accurately (separate audio sources)
• Reduced crosstalk interference
• Better attribution of who said what
• Easier to correct individual speaker errors

How to Enable

Desktop settings (before meeting):

1. Open Zoom desktop app
2. Click Settings icon (gear icon)
3. Navigate to "Recording" tab
4. Locate "Record a separate audio file for each participant"
5. Check the box to enable
6. Settings save automatically

Impact on files:

• One audio file per active speaker
• Master mixed audio file also included
• Total file size increases moderately (20-30%)
• Folder organization: All files in same directory

When to Use This Setting

Enable for:

• Multi-speaker meetings (3+ participants)
• Interviews with multiple people
• Panel discussions
• Any meeting requiring speaker attribution

Can disable for:

• Single-speaker presentations
• Webinars where only host speaks
• Recordings where speaker identity doesn't matter

Note: This setting only affects local recordings, not cloud recordings.

Setting 2: Optimize Recording Quality Settings

Configure video and audio quality for optimal transcription without excessive file sizes.

Audio Quality Settings

Recommended configuration:

1. Open Zoom Settings → Recording
2. Locate "Recording quality" section
3. Choose settings based on need

Best settings for transcription:

• Audio bitrate: 128 kbps (high quality)
• Sample rate: 44.1 kHz or 48 kHz
• Mono vs Stereo: Stereo for separate tracks, Mono acceptable for single track

Why these settings:

• 128 kbps audio: Preserves speech frequencies without excessive file size
• 44.1/48 kHz: Standard professional audio quality
• Higher bitrates (192/256 kbps): Minimal transcription benefit, much larger files

Video Quality Settings

For meetings being transcribed:

• Video quality: 720p (HD) sufficient
• Frame rate: 15 fps acceptable (vs 30 fps)
• Optimization: Check "Optimize for 3rd party video editor" if uploading to AI services

Why video quality matters less:

• AI transcription uses audio only
• Lower video quality = smaller files = faster upload to transcription services
• No transcription accuracy impact from video quality

Recommended: Audio-only recording if video not needed (see Setting 6)

Storage vs Quality Trade-offs

File size comparison (1-hour meeting):

• High quality (1080p video + 128kbps audio): 800-1200 MB
• Medium quality (720p video + 128kbps audio): 400-600 MB
• Audio only (128kbps): 50-80 MB

For transcription purposes:

• Audio-only files upload 10-15x faster
• Same transcription accuracy as full video file
• AI services extract audio from video automatically anyway

Setting 3: Configure Original Sound for Music Mode

Enable high-fidelity audio processing that preserves speech clarity.

What Original Sound Does

Bypasses Zoom's automatic audio enhancements that can distort speech for transcription purposes.

Standard Zoom audio processing:

• Automatic gain control (adjusts volume)
• Noise suppression (removes background sounds)
• Echo cancellation
• Voice optimization

With Original Sound enabled:

• Minimal audio processing
• Preserves natural speech frequencies
• Better dynamic range
• More accurate representation of actual audio

Benefit for transcription:

• AI transcription relies on specific speech frequencies
• Heavy processing can remove frequencies AI needs
• Original audio provides better source material
• Particularly important for accented speech

How to Enable

During meeting:

1. Join meeting
2. Click arrow next to microphone icon
3. Select "Original Sound" toggle
4. Enable for duration of meeting

Note: This is a per-meeting setting, not a permanent default.

Pre-meeting configuration:

1. Zoom Settings → Audio
2. Advanced section
3. Check "Show in-meeting option to 'Enable Original Sound'"
4. Allows enabling during any meeting

When to Use Original Sound

Best for:

• Meetings with clear audio (quiet environment)
• Professional microphone setups
• Accented or non-native English speakers
• Music or audio demonstrations (not relevant for transcription)

Don't use if:

• Significant background noise present
• Poor quality microphone (built-in laptop mic)
• Echo issues in room
• Multiple people in noisy environment

Key insight: Original Sound helps transcription accuracy with good source audio but can hurt with poor source audio.

Setting 4: Enable Background Noise Suppression

Configure Zoom's noise suppression to filter background sounds without distorting speech.

Noise Suppression Options

Zoom offers multiple noise suppression levels:

Auto (Default):

• Zoom automatically adjusts suppression
• Moderate noise reduction
• Balances suppression vs speech quality

Low:

• Minimal noise filtering
• Preserves most audio frequencies
• Use with quiet environments

Medium:

• Balanced noise reduction
• Removes steady background sounds
• Recommended for most transcription

High:

• Aggressive noise removal
• Removes keyboard typing, paper rustling
• May impact speech quality slightly

Recommended for transcription: Medium

How to Configure

Before meeting:

1. Zoom Settings → Audio
2. Locate "Suppress background noise" section
3. Select suppression level from dropdown
4. Choose "Medium" for best transcription balance

Why medium is best:

• Removes distracting background sounds
• Preserves speech frequencies AI needs
• Doesn't over-process audio like "High" setting
• Better than "Low" for typical office/home environments

Trade-offs to Understand

Benefits of suppression:

• Cleaner audio for AI processing
• Removes steady background noise (HVAC, traffic)
• Reduces interference from keyboard/mouse clicks

Potential downsides:

• Can remove some speech frequencies at high levels
• May struggle with multiple speakers talking simultaneously
• Can introduce artifacts in processed audio

Best practice: Test different levels with your typical recording environment to find optimal balance.

Setting 5: Choose Cloud vs Local Recording Strategically

Recording location impacts file access speed, quality, and suitability for transcription.

• Shareable links for team members
• Processing happens on Zoom servers

Disadvantages for transcription:

• Upload time required (5-15 minutes after meeting)
• Requires Zoom paid plan (Pro, Business, or Enterprise)
• Download required before uploading to AI transcription service
• Extra step in workflow

Best for:

• Teams needing shared access to recordings
• Organizations with Zoom Business/Enterprise plans
• Situations requiring automatic backup

Local Recording

How it works:

• Recording saves directly to computer during meeting
• Immediate file access after meeting ends
• No Zoom cloud storage used

Advantages for transcription:

• Immediate file access (no upload wait)
• Works with Zoom Basic (free) plan
• Direct upload to AI transcription service
• Can record with separate audio tracks per participant

Disadvantages:

• Recording lost if computer crashes during meeting
• Uses local storage space
• Must manually backup and share
• Only accessible from recording computer

Best for:

• Free Zoom Basic users

• Faster overall workflow (save 10-15 minutes per meeting)

Exception: Use cloud recording if automatic backup critical and have paid Zoom plan.

Setting 6: Audio-Only Recording for Faster Processing

Record audio-only files when video not needed, dramatically reducing file size and upload time.

How to Enable Audio-Only Recording

Currently not a direct Zoom option, but can achieve similar result:

Method 1: Disable video during recording

1. Start meeting
2. Stop video (click video icon)
3. Start recording
4. Recording captures audio only (with blank video)
5. File size: ~50-80 MB per hour vs 400-600 MB with video

Method 2: Extract audio after recording

1. Record normally (video + audio)
2. Use video software to extract audio track
3. Upload audio file to transcription service

Method 3: Use third-party recording software

• OBS Studio: Can record audio-only
• Audacity: Can capture system audio
• Requires configuration before meeting

Benefits for Transcription

Drastically reduced file size:

• Video + audio: 400-600 MB per hour
• Audio only: 50-80 MB per hour
• 85-90% file size reduction

Faster upload to transcription service:

• 50 MB upload: 1-2 minutes on typical internet
• 500 MB upload: 10-15 minutes on same connection
• 10x faster upload time

Processing speed:

• AI transcription services process audio track only anyway
• No quality difference for transcription between video file and audio-only
• Same accuracy results

When to Use Audio-Only

Ideal for:

• Meetings where video not needed for reference
• Phone conversations
• Interviews focused on audio content
• Situations with limited bandwidth
• Faster transcription workflow priority

• Visual information important (screen shares, presentations)
• Need to reference speaker body language
• Archiving for full meeting documentation
• Organization requires video recordings

Setting 7: File Naming and Organization

Systematic file naming enables easy searching and organization of recordings and transcripts.

Recommended Naming Convention

Format: YYYY-MM-DD_MeetingType_Participants_Topic.mp4

Examples:

• 2025-11-05_Client-Call_Acme-Corp_Q4-Planning.mp4
• 2025-11-05_Team-Standup_Engineering_Sprint-Review.mp4
• 2025-11-05_Interview_John-Smith_Product-Manager.mp4

Why this format works:

• Date first: Enables chronological sorting
• Meeting type: Quick categorization
• Participants: Know who was involved
• Topic: Understand content without opening
• Consistent naming: Easy to search later

Zoom Default Naming

Zoom automatically names files:

• Cloud recordings: Meeting title from scheduler
• Local recordings: zoom_0.mp4 (increments: zoom_1, zoom_2, etc.)

Problem with defaults:

• Generic names don't indicate content
• Difficult to find specific meetings later
• Must open file to determine content

How to Configure Better Naming

For cloud recordings:

1. Name meetings descriptively when scheduling
2. Zoom uses meeting title for recording filename
3. Edit meeting title before scheduling for better filenames

For local recordings:

1. Rename immediately after recording
2. Follow consistent naming convention
3. Create folder structure for organization

Folder Organization Strategy

Recommended structure:

/Zoom-Recordings/
  /2025/
    /11-November/
      /Client-Calls/
        2025-11-05_Client-Call_Acme-Corp_Q4-Planning.mp4
        2025-11-05_Client-Call_Acme-Corp_Q4-Planning.txt (transcript)
      /Team-Meetings/
        2025-11-05_Team-Standup_Engineering_Sprint-Review.mp4
        2025-11-05_Team-Standup_Engineering_Sprint-Review.txt (transcript)
      /Interviews/

Benefits:

• Year/Month folders: Chronological organization
• Category subfolders: Logical grouping
• Recordings + transcripts together: Easy reference
• Searchable by filename: Fast retrieval
