What are the most effective techniques for audio mixing during live streaming and broadcasting?

1 Setting levels

The first step in audio mixing is to set the appropriate levels for each audio source, so that they are neither too loud nor too quiet, and they blend well with each other. You can use a mixer, an audio interface, or a software tool to adjust the volume and gain of each input. You should aim for a consistent and balanced sound that does not clip or peak above 0 dB, which can cause distortion and damage your equipment. You should also leave some headroom for unexpected changes in volume or dynamics.

2 Using EQ and compression

The next step in audio mixing is to use equalization (EQ) and compression to shape and enhance the sound quality of each audio source. EQ allows you to boost or cut specific frequency ranges, such as bass, mid, or treble, to make the sound clearer, brighter, or warmer. Compression reduces the dynamic range of the sound, making the loud parts quieter and the quiet parts louder, to create a more even and consistent sound. You can use a hardware or a software device to apply EQ and compression to each input, or to the whole mix.

3 Applying filters and effects

The third step in audio mixing is to apply filters and effects to modify and improve the sound of each audio source. Filters are devices that remove or attenuate certain frequencies from the sound, such as high-pass filters, low-pass filters, or notch filters. Effects are devices that add or alter certain characteristics of the sound, such as reverb, delay, chorus, or flanger. You can use filters and effects to create different atmospheres, moods, or styles for your live stream or broadcast, or to correct or enhance certain aspects of the sound.

4 Monitoring and adjusting

The fourth step in audio mixing is to monitor and adjust the sound of your live stream or broadcast, using headphones, speakers, or meters. Monitoring allows you to listen to the sound quality and balance of your mix, and to identify and fix any issues or problems that may arise. Adjusting allows you to fine-tune and tweak the settings of your levels, EQ, compression, filters, and effects, to optimize the sound for your audience and your platform. You should monitor and adjust your sound before, during, and after your live stream or broadcast, using a reference track or a feedback loop.

5 Avoiding feedback and distortion

The fifth step in audio mixing is to avoid feedback and distortion, which are two common and annoying problems that can ruin your live stream or broadcast. Feedback is the loud and unpleasant noise that occurs when the sound from your speakers or monitors is picked up by your microphones, creating a loop. Distortion is the harsh and distorted sound that occurs when the sound from your inputs or outputs is too loud or too clipped, exceeding the capacity of your equipment. You can avoid feedback and distortion by using headphones, muting unused inputs, lowering the volume or gain, and using filters or limiters.

6 Learning and improving

The sixth and final step in audio mixing is to learn and improve your skills and techniques, by practicing, experimenting, and analyzing your results. You can learn from other video producers, audio engineers, or online resources, such as tutorials, blogs, or podcasts, to get tips, tricks, and best practices for audio mixing. You can experiment with different settings, devices, and effects, to find what works best for your live stream or broadcast, and to create your own unique sound. You can analyze your results by recording, reviewing, and evaluating your audio mix, and by getting feedback from your audience, peers, or mentors.
