Auralith Forge

Auralith Forge is a browser-based automated mastering service for musicians and producers who want analysis, comparison and export tools around a finished mix. It suits occasional release makers as well as users mastering dozens of tracks each month. The main trade-off is a capable web workflow against a 200 MB upload ceiling and web-only access.

Overview

Auralith Forge analyzes loudness, tonal balance, dynamics and stereo width before choosing EQ, compression, saturation and true-peak-safe limiting. That adaptive approach is aimed at a finished mix rather than a manual mixing session. Reference-track matching and loudness targets give users a defined point of comparison, while an imported JSON processing chain can run as written, subject to the same peak, limiter and quality checks as other processing.

Uploads can be WAV, AIFF, FLAC, MP3, M4A, AAC, OGG, WMA, MP4 or WebM, up to 200 MB. Masters export as WAV or MP3. The limit is generous for many stereo mixes but can constrain unusually long, high-resolution or multichannel files.

Key features

Instant level-matched A/B comparisons remove a common mastering-app problem: a louder result sounding better simply because it is louder. Artist profiles and codec previews provide additional ways to judge how a master translates. Free-account users also receive unlimited chord, key, BPM, chord-progression and LUFS analysis, so the account remains useful for preparation and checking even without frequent paid mastering.

Optional stem separation creates vocal and accompaniment parts for separate rebalancing. It is a targeted choice for mixes whose vocal balance needs independent treatment, rather than a replacement for full multitrack editing. Studio and All-Access add the Professional engine, with separate sub and punch bands and a transient-aware clipper; Indie stays on the Standard engine.

Privacy measures are clearly defined: uploaded audio is not used to train models, connections use HTTPS, and Firebase Authentication handles passwords. Uploaded audio, masters and codec previews are permanently removed from the servers 48 hours after creation. That short retention suits users who download promptly, but it is not a long-term project archive.

Pricing

The Free allowance is best for trying the workflow or a few releases; its three full masters are a one-time quota, while previews remain unlimited. Single Master keeps an occasional user out of a subscription, and Stem Separation is a focused one-off purchase. Indie fits regular but modest output, though it omits the Professional engine. Studio is the practical tier for up to 50 monthly tracks and adds that engine. All-Access is for high-volume catalogs or users who need included stem work and shareable links; its 250-master ceiling is the highest published capacity.

Platforms

Auralith Forge runs on the web. There is no published desktop or mobile application, so offline and native-app workflows are not its strength.

Who it's for

Choose it for automated mastering with measurable analysis, matched-level decisions and codec checking. It is particularly suitable for artists progressing from occasional releases to 15, 50 or 250 masters per month, and for users who need reference matching or separate vocal and accompaniment treatment. Look elsewhere if you require a non-browser workflow, a larger upload allowance or storage beyond the 48-hour deletion window.

Pros and cons

• Pros: level-matched A/B comparisons make processing judgments fairer; unlimited free analysis covers chord, key, BPM, progression and LUFS checks; Studio and All-Access include the more capable Professional engine; WAV and MP3 exports, reference matching and loudness targets support release preparation; explicit 48-hour deletion and no model training address audio privacy.
• Cons: the 200 MB upload cap can exclude unusually large files; the web-only platform rules out native or offline use; Indie lacks the Professional engine; the Free plan's three full-length masters are one-time rather than recurring; retained files disappear after 48 hours, so users must download promptly.

Alternatives

If unlimited mastering at no cost is the priority, AI Mastering offers a free plan with unlimited mastering across web and several other platforms. Matchering is the better fit for users wanting open-source software under GPLv3 with no published paid plans.

RoEx Mastering suits users who want a free preview before paying a credit to download a master. MasteringBOX is worth considering for mobile access and a free daily master with storage and loudness controls.

SoundBoost.ai fits users seeking mobile/web freemium mastering with an annual unlimited option. TrackGleam is an alternative for unlimited free mastering with WAV and MP3 output and no sign-up. Barichord Audio Lab is aimed at users who want manual EQ and effects alongside AI diagnosis. Engineer Guy AI Master Track targets mix feedback and unlimited monthly sessions on its Pro plan.

Verdict

Auralith Forge is a strong choice for musicians who want adaptive online mastering with reliable comparisons, free analysis and a clear path to higher monthly capacity. Choose Studio for regular work that benefits from the Professional engine, or All-Access when stem separation and volume justify it. Occasional users should stay with the one-off options; users needing native apps, bigger uploads or persistent online storage should look elsewhere.
