Can I download my result on the free plan?

Yes, as a preview. The free plan runs the full engine on your whole song, plays the result level-matched against your original, and lets you download that preview. The full-quality file is paid: one track at a time, or unlimited on a plan.

Do the free minutes refill?

No. Ten minutes are granted once at signup and never expire, so there is no clock running. Analysis is never metered, so even after they are spent you can upload any track and see exactly what it needs.

How is a minute counted?

By the length of the source audio, rounded up to a tenth of a minute per job, multiplied by the capability’s published multiplier. A four-minute track separated into stems is four minutes; turned into spatial audio it is eight, because spatial costs 2×. Mastering on a paid plan uses no minutes at all; on the free plan, a four-minute master is four. Mixing counts the length of the mix, not the sum of the stems.

What happens when I run out mid-project?

Nothing that's already running stops. The next submission is refused before it starts, with the exact shortfall, and you're offered a plan or a pack. A job that would overshoot your remaining minutes can't be submitted at all, so there's no such thing as an unexpected overage here.

Do I need a subscription to use the API?

No. API usage is pay-as-you-go on its own meter with a card on file, invoiced monthly to the workspace, available from any workspace including a free one. Plan minutes never pay for API jobs and API credit never pays for Studio jobs: two pools, so neither can quietly drain the other. Test mode is free.

In the cases the terms set out. Payments are final: a minute pack or long-form hours can be refunded only if you ask within fourteen days of buying them and none of it has been used, and a per-track purchase is not refundable once the file has been downloaded, as the purchase screen says before you pay. A defective result is refunded or reprocessed, and a charge you never authorised is reversed. You hear the level-matched result before you pay, so you always know what you are buying. In the EU and the UK you also have fourteen days to withdraw from a distance purchase, which we cannot waive on a subscription.

Pricing

Free to hear. Pay only for what you keep.

Every plan runs every service, the free one included. Plans differ in minutes, queue speed and how much you keep. Nothing is locked behind a tier, and on every plan your audio is never used to train anything.

Five ways to pay

A planFrom $15 a month, unlimited mastering and exports
Per track$2 to 8, quoted before you press it
Minute packs30 or 100 minutes, or hours for long recordings, prepaid
Metered overageOff unless you turn it on, with your own cap
APIFrom $0.15 a minute, pay as you go

Annual billing is 17% less: two months free. Prices are in US dollars and exclude VAT or sales tax where it applies: the amount is calculated at checkout.

Paid plans renew automatically (monthly or annually, whichever you choose) until you cancel. Canceling is self-serve in your settings and takes effect at the end of the period you have paid for.

Max is the top plan, with nothing hidden above it. Enterprise adds contract terms, not a bigger plan.

Choose Max

Free. Ten minutes at signup that never expire. They are a one-time trial rather than a monthly allowance, so spend them on the tracks that matter most.

Max. Max is the top plan, with nothing hidden above it. Enterprise adds contract terms, not a bigger plan.

Unlimited mastering on a paid plan covers your own music, and your clients’ if you master for a living, on one account per person or team. It does not cover reselling our mastering as a service of your own, or submitting from a script. Past 200 masters in a calendar month nothing stops and nothing costs more, but a person looks at the account. Every other service uses your plan’s minutes.

Enterprise

For labels, studios and broadcasters with volume, reserved capacity or contractual obligations.

Reserved capacity, set aside in advance
Committed-use pricing below the published ladder
Contracted retention windows and audited access
A named contact, not a queue

The other three lanes

If a subscription is the wrong shape

Two songs a year isn't a subscription, and neither is an application calling us a thousand times a day. Both have their own lane, at their own rate.

Per track

One track at a time

$0.80 / minute

Never below $2, never above $8 for a track.

Processed something on the free plan and want the file? The export button quotes the exact price before you press it. You get the full-resolution export and lossless comparison for that track, and re-downloading the same version is free forever, because it is your file.

No running meter, no total that assembles itself while you work. A price, then a button.

Prepaid

Minute packs

30 minutes$0.50 a minute: $15
100 minutes$0.40 a minute: $40

Buy minutes outright, use them in the Studio on any plan, and export what they produced at full quality. Plan minutes are always spent first, then packs, oldest first.

Pack minutes expire twelve months after purchase, with an email at thirty days and at seven. The date is on the purchase screen before you buy, not in a footnote after. An unused pack is refundable within fourteen days of purchase; once any of it is used, it is not.

Per processed minute, billed monthly, from any workspace including a free one. Test mode is free. Spend caps are on by default at $50 per workspace and you can raise them: a default that is off is how people find out about a limit from an invoice.

API documentation

For long recordings

Long-form hours

Podcasts, interviews, lectures, audiobook chapters: anything that runs 20 minutes or more is priced by the hour.

10 hours$0.90 an hour: $9
30 hours$0.80 an hour: $24
100 hours$0.69 an hour: $69

Hours pay for restoration and mastering on any recording of 20 minutes or more, on any plan. The length is measured from the file you upload. A shorter recording never uses them; it uses plan or pack minutes as usual.

For a long recording, hours are spent first, then plan minutes, then pack minutes. On a paid plan mastering is already unlimited, so there hours are spent only on restoration. One recording can be up to 60 minutes long.

One-time purchase. Hours never expire. Unused long-form hours are refundable within fourteen days of purchase; once any of them are used, they are not.

Buy hours

Metering

What each capability costs per minute

A minute of one service is not always a minute of another. The rates are published instead of hidden inside a credit, and measuring an upload is never metered at all.

Metering multiplier per capability, applied to minutes of source audio
Capability	Per source minute	A 4-minute track
AI Mastering	×1	4 min
AI Mixing	×1	4 min
Audio Restoration	×1	4 min
AI Vocal Tuning	×1	4 min
Stem Separation	×1	4 min
Spatial Audio	×2	8 min

In the Studio on a paid plan, mastering uses no minutes at all. The ×1 above is what it costs on the free plan, from a minute pack on the free plan, and through the API.

No dark patterns

What we will not do with your money

You are never charged without asking

There is no card on the free plan. Metered overage is off unless you turn it on, and when you do you set the monthly cap yourself. Nothing bills silently, and no job runs that would exceed the minutes you have: a submission that would overshoot is refused with the exact shortfall rather than accepted and invoiced.

Plans renew until you cancel, and canceling takes two clicks

Monthly plans renew monthly, annual plans annually, until you stop them. Every plan gets an email before it renews (about 45 days ahead for an annual plan, about seven days ahead for a monthly one) with the date and the amount, in time to act on it. Canceling is self-serve and takes the same number of clicks as subscribing did, never a phone call, a chat agent or a retention offer you have to decline twice. It takes effect at the end of the period you paid for, we email you a confirmation with that date, and nothing you have already used is taken back.

You hear it before you pay for it

The level-matched comparison against your original plays before any charge, and the exact price is on the button, which is why payments are final. A defective result (a file that will not play, an export at the wrong sample rate) is reprocessed or refunded, as consumer law requires. Statutory rights, including the EU and UK withdrawal right, are never limited by any of this.

What you pay for is compute, measured

The unit is minutes of source audio, rounded up per job to a tenth of a minute, times the published multiplier for that capability. Analysis is never metered. Jobs that fail for our reasons are never metered.
