Live audio or live sound mixing involves mixing instruments, pre-recorded sounds and vocals in real-time. Audio engineers use a software application or console to blend the sounds. If you are working with a console that has various slides as a beginner or experienced audio engineer, it can be intimidating since there is no room for error.
Creating a live audio mix for live performances of any scale requires skills that can take a while to learn. So, if you decide to become a skilled audio or sound engineer, you can consider joining an online live sound mixing course.
Although live audio mixing can be stressful, the rewards are worth it when done right. This article will discuss mastering live audio mixing if you’re starting.
Live Audio Mixing Techniques
It can be scream pretty overwhelming when you’re sitting behind a console with dozens of sliders, especially when mixing audio for live concerts. Here are some techniques for live audio mixing you can master as a beginner.
Prioritize Soundchecks
Soundchecks are essential if you want to produce an excellent live audio mix. To ensure the live audio mix comes out clear and balanced during the performance, you’ll need to check your equipment to ensure they are top-notch.
Take the time to set up and check the volume levels of your microphone, and adjust the equalizers and other effects as needed. Soundchecks help you identify issues that might disrupt the show before it starts. You’ll need to coordinate and communicate with the performers and your team members to ensure the soundcheck is successful.
Manage Transients and Dynamics
Understanding how to manage transients and dynamics successfully is one of the essential skills of audio engineers. The concept behind this skill is that you know how to produce a coherent sound that everyone can hear from any angle.
Transients are fleeting bursts of sound vibrations you hear at the start of a sound. They can be piercing, like the sound you hear on the mic when the head of the drumstick hits the drumhead. It could also occur when you use a guitar pick on the guitar string or emphasize your consonants.
To manage your transients, you can use a technique called shaping, a process where you compress or boost the initial sound to make it more subtle or pronounced.
Dynamics are variations in intensity and loudness in your audio. To manage your dynamics, you can use techniques like compression, limiting, and volume automation tools to balance the spectrum of your audio and create a seamless mix that is cohesive and professional.
Get a Backup Microphone
When mixing live audio, don’t blindly rely on your wireless systems. If you use a lot of wireless equipment during your live audio mix, you’re bound to get some wireless microphone interference. For example, your wireless microphone might fail during the live performance for several reasons, and you might not be able to fix it.
This is why you have to set aside a wired mic and put it on a stand that the performer can use should the wireless mic get faulty. Make sure to pack an additional DI box along with a 1/4-inch cable and set it up at the base of the microphone stand. This will make it easy to switch to the emergency setup when any microphone stops working.
Prioritize Equalization (EQ)
In audio engineering, equalization is an essential step in the mixing process. It enables you to change various frequencies within a sound source. Equalization (EQ) allows you to enhance or lower specific frequencies to create audio balance and intensity. Engineers can sculpt the overall sound and add clarityx to their mix by altering the levels of the low, mid, and high frequencies.
Furthermore, EQ separates the instruments and places them in the soundscape. This is especially important if you want your mix to sound professional and stand out on streaming and broadcasting platforms. Although EQ is generally utilized quietly, it is necessary for producing high-quality songs.
Use Delay Effects
A space within your audio mix is crucial to creating a professional sound. One of the most effective ways to do this is by using delay effects. Delay effects can help you expand your sound’s character, broadness, and depth, making your mix more dynamic and energetic.
Each delay effect, such as Chorus, Reverb, and Echo, has a distinct sound, time and feedback. When you experiment with them, it’ll allow you to create a sound that is unique and creative with your mix.
Timing is also essential when applying delay in your audio mixing. Too much delay can cause your mix to become muddy and lose clarity. To avoid this, pay attention to your settings and ensure the delay enhances rather than detracts from the overall sound quality.

Understand Each Audio Element’s Role
Before you can create a well-balanced audio mix, you have first to understand the function of each component in the overall sound. Variables like the conversations, sound effects, environment, and lyrics are crucial to the live audio mixing process.
The environment comprises the venue’s acoustics and where microphones and speakers are placed. The sound effects and music should work together to create the desired mood and emotion for the scenario. The song lyrics for the live performance should be clear and understandable, not drowned out by background noise or instrumentation.
An understanding of the significance and function of each component will ensure that you make good sound choices that will blend them smoothly during the creative audio mixing process.
Conclusion
Mixing live sounds or audio for a live performance is no walk in the park. It requires artistic intuition and technical know-how. You have to be able to anticipate any possible problems the performance might have with the live audio before it occurs. Knowing this can help you avoid audio issues during live performances.
Fortunately, with the points given in this article, you can begin mastering your live audio mixing to produce authentic, transparent and spectacular live sounds. Don’t be scared to ask for help when you get stuck with your live audio mix, and be sure to utilize online live audio mix courses more often.
