Videos are a great way of creating engaging content for an online course. You might have just finished designing some fantastic materials for your course to ensure your videos are ready to go for students to have the best learning experiences possible. However, even with great visuals and script, students may not be able to enjoy your video to its full quality if the audio is unclear. To ensure students are 100% engaged with the content, here are 5 easy tips on how to record professional audio for your online course.
You don’t need to be a professional sound engineer to be able to record good audio narration. Having an idea of the two types of audio recording setup, single and double system can be super useful. Single setup means that audio is recorded directly to your camera, while double means that your audio and video is recorded separately. You just have to pick the right setup that meets your needs. While single setup can be a huge timesaver, it does come in a cost, as not a lot of camcorder comes with a robust and professional voice recorder. On the other hand, you can get a good external microphone to support your camera that will not break your budget!
Choosing the right equipment is crucial to the success of any project. While most students don’t expect Hollywood-grade post production quality, knowing good equipment choices can assist with the quality of your audio. Make sure you do your research before deciding on which microphones to buy or third-party application to use that can meet your needs. It’s important to note that microphones will sound differently in each person’s voice, so choose one with response characteristics that will make your voice sound the best. If you are low on budget — there is always a way to create DIY microphones. Quick tip: don’t forget to add a pop screen to your microphone to minimise the strong B and P sound, or referred to as ‘plosive’!
Before you press the record button, make sure to check your surroundings. You’ll be surprised with the amount of background noise that will be included in your recording! Turn off some of the things within your control — such as home appliances like air conditioners, fans, and televisions. Be careful of where and how you position your microphone as well! Try to place it slightly away from your laptop or computer since your PC may create a loud humming noise that can disrupt the quality of your audio. Lastly, remind everyone in the room to be quiet during the recording process.
Once the audio is fully recorded, you can try to perfect the quality by using a free third-party audio software such as Audacity and Garageband. These softwares can help you to eliminate ambient noise from your recording. You can also play around and create your own audio preset that can best suit your taste, such as increasing the bass or removing reverb.
Don’t forget to maintain a consistent environment! If you’re recording a lot of video lectures and audio narrations, recording in the same place helps keep the audio clear and consistent. An easy way to estimate a proper distance between the narrator and the mic by using The Spreadhand Method – simply use your hand to measure the space between your mouth and the mic. This small tip can make or break the quality of a recording.
That’s a wrap! Following these easy tips will be sure to bring your videos from good to great. Remember, the creator of Star Wars, George Lucas once said “Sound is half the picture.” If Lucas thinks so, having good and clear audio quality must be critical to your online course!
