Artificial intelligence and machine learning are transforming many aspects of music production, including mastering. AI-powered mastering tools can automatically process tracks to achieve professional sound quality and loudness levels. This guide explores the top AI mastering software available today for polishing mixes.

What is AI Mastering?

AI mastering utilizes machine learning algorithms to apply processing like equalization, compression, limiting, and more to mixes and tracks. The software “listens” to analyze the audio, then makes intelligent mastering decisions to optimize quality.

Key benefits over manual mastering include:

• Speed – AI can master tracks in minutes with no human time required.
• Affordability – Lower cost than hiring professional mastering engineers.
• Ease of use – No advanced audio engineering expertise needed.
• Consistency – AI delivers polished masters time after time.

AI solutions can be ideal for amateur producers and home studios. However, some musicians still prefer human mastering engineers for a personalized touch.

Should You Use AI Mastering?

AI-powered mastering tools make polished, professional-sounding masters far more accessible and affordable than manual mastering. However, there are a few factors to consider when deciding if AI is right for your needs:

Music genre – AI masters well for contemporary, commercial genres. Acoustic, intricate music can pose challenges.

Release plans – If releasing professionally, a human mastering engineer may provide the personalized attention needed for the best quality final product.

Mix quality – AI can struggle with poorly balanced, messy mixes. Quality mixing is key to get the most out of AI mastering.

Ears over eyes – Trust your ears over waveform visuals when judging AI masters. Results may look different but sound better.

Try before you buy – Experiment with demos and free trials before committing to a service or software.

AI Mastering vs. Human Mastering

AI mastering provides benefits like speed, cost savings, and accessibility over human mastering. But human engineers still have advantages in areas like:

• Subtle audio judgments – Humans excel at nuanced tweaks across frequencies.
• Creativity – Engineers make impactful sonic choices relying on taste and artistry.
• Tonal balance – Human ears assess and adjust tonal balance holistically.
• Musical understanding – Engineers mix technical and musical perspectives.
• Customization – Engineers adapt to each client’s unique needs and goals.
• Analog touch – Some engineers incorporate analog gear for natural sound.
• Quality control – Engineers rigorously critique issues and fix problems.

The ideal solution depends on your budget, goals, and mix quality. AI and human mastering can also be combined, with engineers perfecting an AI pre-master. For non-professional use cases, AI mastering provides tremendous value and convenience. But top-tier releases may still benefit most from human mastering artistry.

Tips for Best AI Mastering Results

To get the most out of AI-powered mastering:

• Strive for a high quality, well-balanced mix. Fix mix problems first, don’t rely on mastering to “fix it in the mix.”
• Use reference tracks in the same genre for gain staging and tonal balance comparison. Level match precisely.
• Try multiple genre presets on your track and tweak intensity sliders. See which one sounds most pleasing to your ears.
• Solo instruments and listen critically to check for issues like masking, imbalance, or harshness introduced by AI processing.
• Don’t obsess over waveform images or loudness numbers, trust your ears when judging the final master.
• Use AI mastering services with high resolution output capability for full fidelity.
• For important projects, consider having a professional mastering engineer review and tweak the AI pre-master.
