A Deep Dive into AI Mastering - Everything You Should Know

Mastering is the final and the most crucial phase of the post-production. Since all future recording copies will be based on the master, it will determine the mix's sound and how it sounds across different systems and media formats. Audio mastering is a field that needs deep expertise to optimize the mix. However, many robust new cloud-based services and plug-ins use AI to polish mixes to professional standards in minutes. In this article, we will get into everything you should know about AI mastering.

What is AI Mastering?

AI mastering refers to automated mastering processes powered by artificial intelligence algorithms. It combines technologies like machine learning, digital signal processing (DSP), psychoacoustics, and more to analyze the audio input and make appropriate tonal, loudness, stereo imaging, and corrective adjustments during mastering without human guidance.

Over the years, companies have amassed datasets of thousands of tracks mastered by award-winning engineers. By studying these professional masters and developing deep learning models, AI can map the relationships between mix characteristics and ideal mastering parameter adjustments. Applying an AI mastering solution to your mix measures your track’s dynamics, frequencies, and stereo width. It then automatically determines and applies the processing needed to achieve desired auditory and sonic qualities, emulating human mastering judgment.

AI mastering provides faster turnaround times and more consistent sound. If you are a novice and learning the ropes of mastering, it can save you costs compared to hiring mixing and mastering engineers.

Is AI Mastering Good?

Yes, AI mastering is good, but it comes with some limitations. Modern AI tools provide a cost-effective alternative to hiring mastering engineers. Although they still need to improve in replacing human expertise, their quick learning and analyzing capabilities make them an excellent option. AI mastering has come a long way due to rapid advancement in technology.

AI mastering tools can automate many tasks that would otherwise take hours. They utilize machine learning to study thousands of professional mixes of various genres to understand what constitutes a well-mastered track. The AI will then analyze your mix and apply processing based on the track’s audio. These versatile tools can provide multiple mastering on the same track, providing you with the flexibility to choose one that sounds the best to you. 

Best Tools For AI Mastering

Many AI mastering tools are available these days to help you master your tracks quickly and conveniently. We have listed some of the most popular ones below.
