Free online mastering alternatives, compared honestly

Updated August 19, 2026 · every competitor claim dated inline

If you're hunting for a CloudBounce alternative (it has shut down), a BandLab Mastering alternative without the account requirement, or just a mastering service where "free" means a file you can keep — this page compares the field as it stands in August 2026, with a date on every claim. These are all competent services with real strengths; the differences that matter are in the fine print: what "free" actually gets you, who needs your email, and where your audio goes.

Full disclosure: this page is written by TrackGleam, so read it the way you'd read any vendor's comparison — then check the competitors' pricing pages yourself. We've linked nothing misleading and dated everything to make that easy.

Service by service

LANDR

The most established name, and a genuinely good ecosystem: mastering plus distribution, plugins, samples, and collaboration under one subscription. The catch for bargain-hunters: as of August 2026 the free tier is preview-only behind a signup wall, the cheapest download is $10 for one WAV, and your audio is processed on their servers — with one exception, since their DAW mastering plugin processes inside your DAW without uploading. Watch which tier you buy: Studio Essentials at $99/yr is unlimited MP3 with no WAV at all; WAV starts at Standard ($144/yr, unlimited MP3 plus 36 WAV), and Pro is $192/yr for unlimited WAV and HD WAV. Those are annual-billing prices — monthly costs more. If you want the whole platform, LANDR earns its price; if you just want a track mastered, you're paying for a lot you may not use.

BandLab Mastering

The most generous free tier among the big names: BandLab's help centre states the free plan gives unlimited WAV and MP3 downloads of your mastered tracks, with no per-track fee. Their documentation doesn't mention a watermark and none is widely reported, though the wording we could verify covers the downloads rather than explicitly promising none. The trade-offs, checked August 19, 2026: you must create a BandLab account to download (the master lands in your BandLab projects), audio is processed on their servers, and extra presets plus the intensity control sit behind Pro — $14.99/month, or $99 for the first year and $149/year after. A fine choice if you're already in the BandLab ecosystem; less so if you want to master without an account.

eMastered

Founded by Grammy-winning engineers and respected for tonal balance and reference matching. It's subscription-only, with one product and three ways to pay, checked August 19, 2026: $15/month if you pay $180 upfront for the year, $19/month on the yearly plan billed monthly, or $39/month month-to-month. There is no pay-per-track option. Read the middle one carefully — eMastered's own pricing copy describes it as a one-year commitment, and while their terms do let you cancel before a renewal date, payments already made are non-refundable, so it is effectively priced as a year. The free tier is a preview after signup — there are no free downloads. Worth it for high-volume releasers who like its sound; expensive for occasional use.

Waves Online Mastering

Built by one of the most trusted names in pro audio plugins, with quality to match the brand. Pricing note worth reading twice: as of July 2026 — the one service on this page we did not re-check in the August pass — the advertised "$1.99 per track" is the per-track math of a $71.64/year subscription (36 credits); a single credit is $3.99, and the free tier is a 30-second preview. TrackGleam's AI master is $1.99 flat, one time, no plan required — so if that number is what caught your eye, check which version of it you're getting.

CloudBounce

Gone. As of August 19, 2026 the CloudBounce site is unreachable, and CD Baby — which resold CloudBounce mastering — ended that partnership in February 2025. It still appears in “best of 2026” roundups, which is a useful test of whether anyone actually checked. If you're searching for a CloudBounce alternative, the closest successor is Image-Line's FL Cloud Mastering, or a browser tool like TrackGleam — which, running on your device rather than rented cloud servers, has no per-track compute bill and can keep its free tier free.

TrackGleam (that's us)

One job: mastering, in your browser. The free tier is a real downloadable WAV/MP3 — no signup, no watermark, no cap — because all 14 stages of the Gleam Engine V2 run on your device and your audio never uploads. Masters target release-competitive loudness (Auto ≈ −11 LUFS, streaming-safe −14 on Low) at a −1.0 dBTP ceiling, with a volume-matched A/B. The paid tier comes as five AI mastering engineers — punch, warmth, space, energy or transparency — each reading 60+ measurements of your track and adapting to it; every one previews free, and switching is one tap. (They’re fictional TrackGleam characters — creative mastering directions, not real people.) The optional AI-Enhanced Master is $1.99 one-time (Creator Pack: 10 for $5, credits never expire; heavy users can add the optional Producer plan — $8.99/month or $89.99/year — for unlimited masters under fair use), with a 14-day money-back guarantee on one-time purchases. No distribution, no plugins, no ecosystem — deliberately.

How to read "free" in this market

A pattern worth knowing before you upload anything anywhere: most mastering services use the free tier as a demo — you hear your own track improved, then hit the paywall at the download button. That's not a scam, but it's not "free mastering" either; it's a free preview. As of August 2026, of the services above only BandLab (after signup) and TrackGleam (no signup) let you actually keep a free master. The second thing to check is where your audio goes: every cloud service processes your unreleased track on its servers, while TrackGleam's processing happens in your browser — a claim you don't have to take on faith, since your browser's Network tab will show no audio leaving your machine.

The third thing to check is album pricing — per-track fees compound fast on a 12-track release, and subscriptions bank on you forgetting to cancel. TrackGleam's bulk queue batch-masters a whole album to the same release-ready target (−11 LUFS default, −14 streaming-safe on Low, all under a −1.0 dBTP ceiling), and any paid purchase from $1.99 unlocks it forever; the math and the walkthrough are in how to master a whole album at once.

Frequently asked questions

What is the best CloudBounce alternative?

CloudBounce has shut down — its site is unreachable as of August 2026, and CD Baby ended its CloudBounce mastering partnership in February 2025 — so any current option is an alternative. If you liked CloudBounce for cheap, fast, no-fuss masters, TrackGleam covers that ground for free: masters render in your browser with no signup and download as real WAV/MP3 files, and the optional AI master is $1.99 one-time. If you want the closest successor to CloudBounce itself, Image-Line's FL Cloud Mastering covers similar ground for FL Studio users.

Is there a BandLab Mastering alternative without a signup?

BandLab Mastering is genuinely free and unlimited — its help centre says the free plan gives unlimited WAV and MP3 downloads — which is rare. But as of August 2026 you must create a BandLab account to download, your audio is processed on BandLab's servers, and extra presets plus the intensity control sit behind the paid Pro tier ($14.99/month, or $99 for the first year and $149/year after). TrackGleam requires no account at any point, processes audio in your browser without uploading it, and downloads full-resolution WAV.

Are any online mastering services actually free?

As of August 2026, most "free" tiers are previews: LANDR, eMastered, and Waves let you hear a master (Waves: 30 seconds) but not download it without paying. BandLab is genuinely free to download after signup. TrackGleam is free to download with no signup, no watermark, and no cap — the paid part is an optional $1.99 AI-enhanced version.

Why can TrackGleam be free when others charge?

Because the processing runs on your device, not on our servers. Cloud mastering services pay compute and storage costs for every track, so they have to gate downloads. TrackGleam's mastering costs us almost nothing per track, so the free tier can be a real product. We make money when someone chooses the optional AI-Enhanced Master at $1.99 one-time.

Do these services upload my audio to their servers?

As of August 2026: LANDR, BandLab, eMastered, and Waves all process your track on their servers, so yes — your unreleased audio is uploaded (LANDR's DAW mastering plugin is the exception — it runs locally). TrackGleam runs its whole chain — the 14-stage core and every GleamAI stage — in your browser; the audio never leaves your device, which you can verify in your browser's Network tab.

What loudness should an online master target?

For streaming, the widely used reference is −14 LUFS integrated with true peaks no higher than −1 dBTP, since major platforms normalize playback around that loudness. TrackGleam's Auto targets release-competitive loudness (about −11 LUFS; genre styles −9 to −15, with a −14 streaming-safe Low intensity) at a −1.0 dBTP ceiling, and shows a volume-matched A/B so you judge tone, not just loudness.

Test the claim in two minutes

Every still-operating service above will let you hear your track mastered. Only some will let you keep it. The quickest way to compare is to run your own track through the free tier here — no account, nothing to cancel — and A/B it against anything else.
