Our verdict on Aurora
Aurora is a cloud-based AI audio processing platform for music producers and independent artists. Its core workflow separates a mix and a reference track into seven stems: vocals, kick, snare, toms, hi-hats, bass, and other. Aurora then applies independent processing, reference-track matching, EQ, level matching, and cross-stem balance checks. It is suited to solo producers and small teams seeking automated mastering without manually handling each technical mastering step.
Pricing is structured around a seven-day trial and paid Pro access. According to the published plan listings, annual billing is $16 per month and includes stem-level mastering, reference-track matching, and unlimited masters. Monthly billing is $20 per month and lists 30 minutes of audio processing per month, 20 stem matching credits per month, 10 GB of cloud storage, and priority processing. The trial requires a card. Buyers should compare the billing options carefully because the listed allowances differ by plan presentation.
Aurora’s standout feature is its narrow focus on stem-aware mastering. Automatic seven-stem separation, reference-track uploads, independent processing, and cross-stem checks give it a workflow centered on matching a mix to a target rather than applying only broad stereo mastering. Cloud storage keeps uploaded and processed audio within the web service, while email and community support provide the listed support channels. Aurora is a strong fit for producers who want reference-based, automated stem processing in a browser. It is less suitable for users who require a desktop application, broader platform coverage, or clearly specified WAV output and loudness-target support.
