AI Mastering

Overview

AI Mastering is an AI-powered audio mastering service designed to improve music sound quality. Its automatic mastering aims to bring tracks closer to commercial music, while a limiter balances loudness and dynamic range. Users can work through the web interface, an API, or an offline desktop version; the maker says its focus is shifting toward the desktop version rather than the API.

Online mastering involves a wait that users cannot shorten. The maker suggests the offline version as an alternative when that wait is a concern. The offline version does not share the online service's file limitations: its maximum file size depends on the computer's memory.

AI Mastering supports reference track matching, loudness targets and WAV export. The maker says users retain full control over their mastered tracks, without service restrictions.

Key features

The web interface accepts audio by drag and drop and lets users customize target loudness, mastering level and output format. Spectrum and loudness analysis provide ways to examine a track alongside those settings. Supported input formats are WAV, MP3 and MP4.

A bass preservation option can reduce attenuation in low frequencies. The maker says frequencies up to 24 kHz are possible when the source sample rate is at least 48 kHz and that same rate is selected in custom settings.

The API handles audio upload and download, mastering, and changes to target loudness and mastering level. Its documentation links to JavaScript (Node) and Ruby client libraries and tutorials.

Pricing

AI Mastering is free. The Free Plan is 0.00 USD per free, billed at $0 / Month, and includes Unlimited Mastering. A free plan is available.

Platforms

Listed platforms are Android, API, extension, iOS, Linux, macOS, self-hosted, web and Windows. The service also has an offline desktop version. Supported input formats are WAV, MP3 and MP4, and WAV export is available.

Who it's for

AI Mastering may suit musicians and other users who want automated mastering with controls for loudness, mastering level and output format. Its analysis tools can be useful to those who want to inspect spectrum and loudness, while the bass preservation setting and reference track matching provide additional options for shaping a result.

The online service has a wait that cannot be shortened, so users who need to avoid that online delay may prefer the offline version. Its file-size limit depends on the computer's memory rather than matching the online service's limits. Users interested in integrating mastering into a workflow can use the API, though the maker says development focus is shifting toward the offline version.

Pros and cons

• Pros: Free plan with Unlimited Mastering; supports reference track matching, loudness targets and WAV export; offers customizable mastering controls and spectrum and loudness analysis; provides web, API and offline desktop options.
• Cons: Online waiting time cannot be shortened; offline file-size capacity depends on the computer's memory; the maker says its focus is shifting away from the API toward the offline desktop version.

Alternatives

Other options in AI Music Mastering Software include Matchering, SoundBoost.ai, TrackGleam, SongUp AI, HanoLab Mastering, MasterForge, Tunr and Barichord Audio Lab.

Verdict

AI Mastering combines automatic processing with adjustable loudness and mastering level, audio analysis, reference matching and WAV export, with a free plan listed at $0 / Month. Its online waiting time is an important limitation, while the offline desktop version offers a way around that wait and has file-size capacity determined by the computer's memory. The choice between its interfaces depends on whether online convenience, offline processing or API integration matters most.
