The Role of Audio and Video in E-learning

In today’s fast-paced corporate world, compelling learning experiences are crucial for fostering professional growth and staying ahead of the competition. Audio and video elements bring a dynamic and engaging dimension to e-learning, enabling participants to absorb information more effectively.

However, audio and video content are not intrinsically better than textbooks or other traditional educational forms. You need to expertly craft them to leverage their potential. According to researchers at Vanderbilt University, it is imperative to consider three key factors when designing educational content: cognitive load, student engagement, and active learning. 

To put it in perspective, let’s look at the advantages and disadvantages of each learning medium.

📌 Text

Using plain text is the simplest form of teaching a new subject. It is comparatively easy to write everything you know in text. You can even add images to your textbooks or handouts to better illustrate the topic. Furthermore, it is very easy to replicate text because printing is relatively cheap.

Unfortunately, it relies solely on the visual channel. This overloads it and reduces learning efficiency. This issue can be solved with screen-reading software like Google’s Screen Reader or Speechify. It also heavily relies on the student’s reading speed. The human attention span is limited, so a student will only learn so much information in a given time.

📌 Audio

Audial teaching is another classic method. We see it being used every day at most educational establishments. These can be lectures or seminars where new information is given via speaking. This can also be extended to audio recordings or podcasts.

On the downside, it requires a lot of effort from the speaker. You usually have to train to speak to a classroom freely. On the other hand, if you are doing a recording, you must ensure you have the necessary equipment and proper speech training. Otherwise, you will ruin your recording with either poor sound or poor presentation.

To add to that, just like text, audio only uses one learning channel, thus overloading the student and reducing educational outcomes. 

📌 Interactive Slides

Plain text naturally evolved into slides. Traditional slide presentations are pretty easy to make with the most basic computer tools, but they offer barely any improvement over text.

However, the new generation of slides is here with interactive slide makers like Articulate Storyline, Elucidat, and Adobe Captivate. Unlike their predecessors, you can interact with any content in them. These are typically filled with hyperlinks, hotspots, and other navigational tools. They allow you to jump freely from slide to slide or get additional information or proof on chosen topics. 

This approach is becoming increasingly popular for academic and corporate education. While it offers greater flexibility, it also frequently misses the point of utilizing both visual and audial learning channels. Besides, some authoring tools can generate synthetic VO narration for your slides.

📌 Video

The addition of video technologies in e-learning is widely recognized as a breakthrough in the field. If you play your cards right, you can achieve outstanding results. Videos strongly emphasize the use of both audial and visual learning channels. This allows you to explain complex topics and processes without overloading the student. For example, you can explain complex economic or scientific concepts. 

Modern video editing software allows you to create outstanding visuals, layer voice-over, and sound effects, and add subtitles and captions for accessibility. 

Unfortunately, the biggest drawback of videos is their price. Traditional video creation, be it live or animated, costs a pretty penny and even an experienced team might take a while to complete a short video depending on the requirements. Moreover, it is hard to edit the content if it is already released.

However, technologies used for creating e-learning courses have improved, and we now have AI tools like Synthesia, Rephrase.AI, and Colossyan. They can generate lifelike videos of talking heads perfect for corporate education. The use of this technology in e-learning can phenomenally speed up production and drastically reduce costs. It still produces some uncanny valley effect, but it does not affect educational outcomes, according to research made by our partners.

📌 Interactive Experiences

As we have learned, the more learning channels you use, the better the educational outcomes. Outside of hands-on experience, nothing can beat computer simulations for learning. The combination of audio-visual feedback and the interactive component lets students feel like they are in the real thing, performing surgery or flying a jet.

Obviously, this is the longest-to-make and the priciest option of them all. Therefore, you should resort to it in the edge cases, where hands-on experience can be the difference between life and death.

Key Audio Technologies for E-learning

Audio technologies in e-learning can range from easy-to-use tools with basic functionality (like Audacity or GarageBand) to complex professional tools (like Adobe Audition or LogicPro). Your choice will depend on your goals, resources, and experience. 

For example, Audacity is a free tool that is easy to pick up and record audio almost immediately. You only need a basic microphone (even a USB mic will work) and some time. The tool can also remove static noises, do cuts and fades, add special effects, equalize frequencies, and more. If you are on a budget, this might be the perfect choice since it is completely free to use, even for commercial purposes.

Unfortunately, it lacks the flexibility and functionality of a more robust tool like Adobe Audition. Sure, the subscription price will bite a big chunk off your budget, but it is well worth it for a professional tool, especially when given to a professional. It offers superb performance, more features, and a modern, intuitive design.

If more than one person works on the audio, choosing a tool like Soundation might be the solution. It allows multiple users to work on the same piece simultaneously. Moreover, it is browser-based, so you would not have to download anything—perfect for a quick cut or pitch correction.

In essence, sound-recording technologies are not too different from one another and offer the same features with a few differences. The choice is a matter of taste, experience, and budget.

Key Video Technologies for E-learning

Audio and video educational technologies go hand in hand. We’re not in the 1900s anymore, so all video is expected to have some sound, and video tools are there to help you. They will assist you in syncing and segmenting your audio, adding special effects and background music, etc.

Most e-learning video software tools are divided into three broad categories: 

  • Lightweight. These are limited in functionality but can help with basic stuff, like cutting, overlaying and syncing audio, creating transitions, and more. These tools include Windows Movie Maker, Filmora, and Lightworks.

  • Professional. These will allow you to do everything you can think of, from chroma keying to Michael Bay-worthy special effects. This category includes tools like Adobe Premiere Pro, Final Cut Pro, and Autodesk Smoke.

  • Templates. Businesses asked for an easy way to make high-quality promotional and educational videos without breaking a sweat, and the industry responded. With tools like Powtoon, Visme, and Vyond, you repurpose their templates for your needs. For example, you can make an animation of characters using the new product and explain it to your coworkers.

    Just like with audio tools, the choice depends on your goals, experience, and personal taste.

Complex Tools for Creating E-learning Courses

This category includes a wide range of technologies for e-learning development. They have a wide variety of applications and can have a wide array of features or be hyper-focused on providing the best experience in one specific facet of e-learning.

For example, we have authoring tools like iSpring and Articulate Storyline. They practically erase the borders between synchronous and asynchronous multimedia, allowing you to create online courses that are almost indistinguishable from their live counterparts. You can effortlessly create presentations, add subtitles to videos, record and synchronize audio, and much more. Your students will access your courses directly on their platforms, which have excellent UI and supreme customer support to resolve any possible technical issues.

On the other hand, we have tools like Synthesia, Elai, and Collosyan Creator, which allow you to take AI avatars and make them explain whatever you need. You can then easily translate the texts into multiple languages and add subtitles without sacrificing much of your time or budget.

Finally, there are simpler tools that can still enhance your teaching capacity. They do not necessarily create new content but improve already existing material. Services like Amberscript,, and allow you to add subtitles, subheadings, polls, and other interactive elements to pre-existing videos. This both promotes accessibility in multimedia and improves learning outcomes.

Yes, AI-powered tools have revolutionized video creation for e-learning. Tools like Synthesia, Elai, and Collosyan Creator utilize AI avatars to generate lifelike videos with customizable characters. These tools significantly speed up production and reduce costs without sacrificing educational outcomes.

How important are audio and video elements in e-learning courses?

Audio and video elements are crucial for effective learning. Students can only achieve great educational outcomes if the learning material uses multiple learning channels simultaneously. For example, well-made videos with suitable audio can use audial and visual channels. It is vital not to overload one channel with critical information while cluttering another with useless noise. For example, talking head videos can be great for explaining simple concepts, but they barely function when dealing with complex subjects that require visual imagery.

Which tools should I choose for my e-learning project?

The choice depends on your goals, available resources, and personal experience. It is recommended to assess your specific requirements and consider factors like functionality, ease of use, and budget before selecting the most suitable tools for your e-learning project.
