AI Mastering review
A free mastering service with useful controls, analysis, references, and API access.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AI Mastering is an online service for music creators who want automatic audio mastering without a subscription. It processes uploaded music and provides downloadable mastered audio through a web application, with a Windows desktop application and API also available. The workflow supports automatic AI mastering alongside target-loudness customization, mastering-level customization, output-format selection, spectrum analysis, loudness analysis, and reference-audio selection.
Pricing is straightforward: the Free Plan costs $0 USD per month and includes unlimited mastering. The published offering also includes API upload, download, and mastering operations, giving creators and developers a way to incorporate mastering operations into their own workflows. Supported inputs include WAV, MP3, and MP4, while output-format customization includes multiple WAV and MP3 options. This combination makes the product particularly suitable for users who need recurring mastering access without a paid tier.
The main trade-off is focus. AI Mastering covers the core mastering workflow, technical analysis, reference audio, and several access points, but it does not provide a paid plan for buyers seeking tiered capabilities. Verified integrations are also not part of the listed feature set, so teams that depend on a broader connected ecosystem may prefer another service. Choose AI Mastering for free, flexible online mastering with adjustable loudness and mastering controls; look elsewhere if paid-plan options or established integrations are central requirements.
