1 Check your network

Network bandwidth, latency, jitter, and packet loss are all major factors that affect the quality of voice and video calls. Bandwidth determines the resolution and frame rate of video, while latency affects synchronization and responsiveness. Jitter causes glitches and interruptions in audio and video, while packet loss leads to distortion and degradation. To optimize your network, you should use a wired connection instead of wireless to reduce interference, close any applications or devices consuming bandwidth, test your network speed and quality with online tools, and adjust call settings to match network conditions.

The biggest issue with voice and video is latency. Traditional IP networks are designed to throw bandwidth at any slowdowns and that does not help for voice or real-time video. Jitter is just a symptom of a high latency network that needs work to reduce not only the jitter but also the latency. A two-wire network will cost more and pretty much double the network infrastructure, but as a business you will have to decide about the trade off. If you have something that's life-safety, there's no option other than a two-wire network with nothing else on the voice side of things. And this is 100% wired. Wireless is great, but not reliable for anything critical.

2 Upgrade your hardware

The hardware you use, such as your computer, camera, microphone, speakers, or headset, also plays a role in the quality of voice and video calls. Poor audio and video quality can be caused by hardware issues, such as noise, echo, feedback, blur, or lag. To optimize your hardware for calls, you should choose a device that meets or exceeds the specifications of your call platform. Additionally, make sure to update your device drivers and software regularly for compatibility and performance. Clean your device and peripherals to prevent dust or dirt from affecting their functionality. Position your camera and microphone properly to capture your face and voice clearly while avoiding background distractions. Lastly, use a high-quality headset or earphones with a noise-canceling microphone to improve sound quality and reduce ambient noise.

3 Optimize your environment

The environment you are in when making voice and video calls can have a big impact on call quality. Factors such as lighting, acoustics, and background can affect visibility, audibility, and the impression you convey. To ensure your environment is optimized for calls, select a quiet and well-lit place with natural light or a soft lamp in front of you. Avoid sources of noise and echo such as fans, air conditioners, windows, doors, or hard surfaces. Additionally, use a plain or neutral background that does not distract or interfere with your image, or use a virtual background if your call platform supports it. Dress appropriately and comfortably for the purpose and context of your call and remember to maintain eye contact and body language that show your attention and interest.

Acoustics in general is both often overlooked but also extremely important in terms of recording of any type. This goes from applications such as FaceTime, Zoom, or Discord to live events, and studio work, to even recordings of gunshots one might use in a video game. If you have a noisy environment or one that echoes in a bad way, you won’t have a decent-sounding recording, even with a good system.

4 Follow the etiquette

The etiquette you follow during a voice or video call can have a significant impact on the quality of the call and the communication and collaboration of its participants. To ensure that you are following proper etiquette, it is important to prepare in advance, join your call on time, introduce yourself and your role, mute your microphone when not speaking, and be polite and courteous. Additionally, you should use the chat or raise hand feature to ask or answer questions, and avoid interrupting, dominating, or criticizing others. Following these etiquette rules can help to build respect and rapport among call participants.

There is a distinct difference between calls where etiquette is followed and calls where everyone is trying to talk at once. Staying on topic, asking only relevant questions, and being respectful of both the time and the opinions of others in the call can make all the difference.

5 Monitor and troubleshoot

Monitoring and troubleshooting is a key factor in ensuring good voice and video call quality. You should use the indicators and tools provided by your call platform to check and adjust your call quality. It is also important to ask for and give feedback to your participants. If possible, you should record and review your call to evaluate your call quality and performance, so that you can identify any areas for improvement. Finally, you should learn from your experience and best practices, and apply them to your next call.

If you struggle with acoustics on a call but don’t have a lot of background noise, look at your environment. An environment with less padding will less absorption, and thus more echoes. Try recording in a bedroom or on a couch in a room with carpet. Move your setup around the house and make voice recordings anywhere you would be comfortable joining the meeting from to see where you get the best recording. Also, A/C is often loud (but not as loud as crying toddlers). It may help to turn it off!
