1. What is Audio Conferencing?
Audio conferencing (also called an audio conference or conference call) is a meeting format where multiple participants connect via voice only—no video feed is involved. According to one definition, it is “the process of using electronic communication channels to conduct meetings between three or more participants who communicate using audio only.” Video Conferencing Software+2Teachfloor+2
Types & Details
- Participants can join from different locations using phone lines (PSTN) or internet-based voice (VoIP). Mitel+1
- Three main system types:
- Distributed (remote participants) Video Conferencing Software
- Local (participants in the same room) Video Conferencing Software
- Integrated (mixed remote and in-room participants) Video Conferencing Software
- The participants dial into a central “conference bridge” or join via a link. Microsoft Learn+1
Why Use Audio Conferencing?
- It is cost-effective: minimal hardware required, less travel needed. Video Conferencing Software+1
- It is accessible: people can join via phone or basic internet connection. Dialpad+1
- It is simple and fast to set up: good for routine check-ins or when video is not necessary.
2. What is Video Conferencing?
Video conferencing is a meeting format where participants connect in real time using both audio and video, and typically other collaboration features such as screen sharing, chat, and more. One recent definition describes it as “a live, visual connection between two or more remote parties over the internet that simulates a face-to-face meeting.” TechTarget+1
Key Features
- Participants see and hear each other, which supports richer interaction.
- Typically includes features like screen sharing, chat, virtual backgrounds, recording, etc. Webex
- Requires more resources (camera, microphone, stable broadband, etc) than audio only. Owl Labs+1
Why It Matters
Video conferencing enables collaboration and connectivity across distances in a way that more closely resembles in-person interaction. It has become essential for remote work, global teams, education, training, and many other scenarios.
3. Audio vs Video: Key Differences
Here’s a breakdown of how audio and video conferencing differ, and how to decide which is right for your situation.
| Feature | Audio Conferencing | Video Conferencing |
|---|---|---|
| Equipment & Setup | Simple: phone or headset, dial-in number or link. Minimal bandwidth required. Mitel+1 | More complex: camera, mic, display, stable internet, good lighting. GeeksforGeeks+1 |
| Visual Cues & Engagement | No video → lacks facial expressions, body language, eye contact. GeeksforGeeks | Video allows non-verbal cues, richer engagement, collaboration. |
| Use Cases | Large group updates, audio-only calls, low-bandwidth participants. | Interactive sessions, training, collaboration, visual feedback. |
| Cost & Bandwidth | Lower cost, lower bandwidth, fewer hardware demands. | Higher cost/hardware/bandwidth, but higher engagement. |
| Participant Flexibility | Very flexible, accessible from phone. | Flexible but participants need camera/mic and better connection. |
| Ideal For | Voice-only info sharing, check-ins, those without video capacity. | Deep interaction, when seeing each other or sharing visuals matters. |
The takeaway: neither format is inherently “better” in all cases. Choose the tool that best fits the purpose of your meeting, the participants, and the available resources.

- Client or stakeholder presentations: Video conferencing is often better when you need to show slides, demonstrate products, or engage visually.
- Training and webinars: Video conferencing supports screen sharing, Q&A, visuals—ideal for learning or interactive sessions.
- Remote/hybrid collaboration: Video aids in showing presence, enabling breakout discussion, sharing whiteboards.
- Large global broadcasts: Sometimes audio conferencing is used for large-scale broadcasts where visuals are less critical.
- Education and tele-health: Video conferencing enables seeing the participant, which matters in training or health consultations.
By mapping the format (audio vs video) to the scenario, you improve meeting effectiveness.
6. How They Work: Technology & Setup
To understand how audio and video conferencing work, here are the main technology and setup details.
Audio Conferencing Setup
- Participants dial-in via phone or VoIP to a conference bridge hosted on the network. Microsoft Learn+1
- Minimal equipment needed: phone, headset or microphone/speaker, sometimes a computer.
- The network load is lower compared to video, so it works even where bandwidth is constrained.
Video Conferencing Setup
- Requires camera/webcam, microphone/headset, display or screen, stable internet connection with adequate bandwidth. Owl Labs+1
- Software or platform (e.g., Microsoft Teams, Zoom, Google Meet) manages the meeting logistics, participants, permissions, screen share, recording. Webex
- Data flows over IP networks: video streams, audio streams, sometimes shared documents. Compression, codecs, and network quality affect experience. arXiv+1
Key Deployment Considerations
- Security & privacy: control access, ensure encryption.
- Network & bandwidth: QoS, stable upload/download speeds, low latency for video.
- Usability: invitations, dial-in links, mobile support.
- Accessibility: captioning, dial-in for audio only, accommodating varying connectivity.
7. Common Challenges & Pitfalls
Even with good technology, audio and video conferences can face hurdles. Recognising them helps you mitigate problems.
Technical Failures
- Poor audio quality, echoes, dropouts, especially if bandwidth is low. GeeksforGeeks
- Video issues: camera quality, lighting, low resolution, lag.
- Compatibility issues: devices, platforms, mobile vs desktop differences.
Meeting Fatigue
Video calls in particular are linked to “meeting fatigue” due to constant screen time, self-view, long durations and reduced natural breaks.
Engagement & Distraction
Audio only lacks visual cues so participants may multitask or lose track. Video may reduce multitasking but introduces risks of distraction or privacy concerns.
Mis-use of Format
Defaults to video when audio would suffice => higher cost and participant strain. Or uses audio only when video would add value => may lose clarity or engagement.
Security & Inclusion
- Risk of uninvited participants, insufficient meeting controls.
- Hybrid meetings may exclude remote participants if in-room participants use different formats.
By anticipating these issues—and choosing the format and logistics carefully—you can design more inclusive, effective meetings. Before joining a virtual meeting, make sure your setup is ready — here’s what you should do first before entering a video or audio conference.
8. Best Practices for Effective Conferences
Here are actionable tips to improve your virtual meeting game—whether audio or video.
Preparation
- Send agenda and meeting links or dial-in details ahead of time.
- Test equipment (mic, camera, internet) before the meeting.
- Choose the right format (audio vs video) based on purpose and participants.
Format Selection
- If you’re sharing information and visuals are not necessary: choose audio.
- If you need collaboration, feedback, visual cues: choose video.
- Consider hybrid formats for mixed connectivity or remote/in-room mix.
Engagement & Etiquette
- For audio: mute when not speaking, clearly state your name when you speak.
- For video: good lighting, camera angle, consider background, turn on video if possible but respect bandwidth.
- Encourage interaction: chat, raise-hand, polls, break-out rooms.
- Include all participants: ensure remote or dial-in users can participate fully.
Accessibility & Inclusion
- Provide captioning or transcript.
- Offer dial-in for low bandwidth participants.
- For video, ensure audio is clear, visuals are appropriate, participants comfortable.
Follow-Up
- Share meeting notes, recordings (if video), action items.
- Ask for feedback on meeting format, technology issues.
- Review what worked and what didn’t so future meetings improve.
Common Mistakes & How to Avoid Them
- Mistake: Scheduling every meeting as video out of habit. Instead: Evaluate if video adds value.
- Mistake: Ignoring audio-only participants in hybrid meeting. Solution: Include them, repeat visual cues verbally.
- Mistake: Not testing technology beforehand. Instead: Conduct tech check before main meeting.
- Mistake: Over-long video meetings. Instead: Keep meetings focused and drive purpose.
