Free online mastering alternatives, compared honestly

If you're hunting for a CloudBounce alternative (it shut down in April 2025), 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 July 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.

Master a track free — no signup

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 July 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. 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. Full TrackGleam vs LANDR comparison →

BandLab Mastering

The most honest free tier among the big names: unlimited masters, no watermark, no per-track fee. The trade-offs, as of July 2026: you must create a BandLab account to download (the master lands in your BandLab projects), audio is processed on their servers, exports are 16-bit regardless of source, and half the presets plus the intensity control require a paid Membership. A fine choice if you're already in the BandLab ecosystem; less so if you want full-resolution WAV without an account.

eMastered

Founded by Grammy-winning engineers and respected for tonal balance and reference matching. It's subscription-only: as of July 2026 the month-to-month plan is $49/month, and the advertised "$19/month" is a 12-month commitment (roughly $156/year if paid upfront). 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 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 — so if that number is what caught your eye, check which version of it you're getting.

CloudBounce

Gone. CloudBounce ceased operations in April 2025 — a business decision by its owner, with the technology folded into FL Studio's FL Cloud. Lifetime license holders were offered an FL Studio license rather than refunds. If you're searching for a CloudBounce alternative, the practical successors are FL Cloud (same engine, inside FL Studio) 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 −14 LUFS / −1.0 dBTP streaming loudness with a volume-matched A/B. The optional AI-Enhanced Master is $1.99 one-time (10 for $5, 100 for $20, $99 lifetime with 50/month fair use), with an automated 14-day money-back guarantee. 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 July 2026, of the services above only BandLab (after signup, at 16-bit) and TrackGleam (no signup, full WAV) 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.

Frequently asked questions

What is the best CloudBounce alternative?

CloudBounce ceased operations in April 2025 and its technology was folded into FL Studio's FL Cloud, 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 — less than CloudBounce's old $10.90 per-track price. If you specifically want the old CloudBounce engine, it now lives inside FL Studio's FL Cloud subscription.

Is there a BandLab Mastering alternative without a signup?

BandLab Mastering is genuinely free and unlimited, which is rare — but as of July 2026 you must create a BandLab account to download, your audio is processed on BandLab's servers, exports are 16-bit, and 4 of the 8 presets plus the intensity control sit behind a paid Membership. 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 July 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, at 16-bit. 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 July 2026: LANDR, BandLab, eMastered, and Waves all process your track on their servers, so yes — your unreleased audio is uploaded. TrackGleam runs its whole 14-stage chain 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 targets −14 LUFS / −1.0 dBTP by default 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.
