Denoisa is a pay-as-you-go noise remover, so you don’t need a subscription. Choose your file above and play the free 30-second preview of both modes on your own recording. Files up to 5 minutes are free to clean with Standard, with no account. For longer files, buy a one-time credit pack: 1 credit cleans 1 minute with Standard, and pack credits never expire.
Hear the result before you pay
Noise removal is hard to judge from a demo, because it depends on your noise and your voice. So every file gets a free preview of its first 30 seconds, cleaned with both Standard and Enhanced, and you can switch between them and the original while it plays. You don’t need an account or a card for this.
The Standard preview runs in your browser. The Enhanced preview sends those 30 seconds of sound to our servers, and only when you click it. If the noisy part comes later in the file, cut a short clip of that part and preview it instead.
Sample: a voice recorded over real city traffic.
One-time credit packs
Credits are charged per minute of your file, rounded up to the next whole minute. Standard uses 1 credit per minute and Enhanced uses 2. Pack credits never expire, so a pack bought for one project still works next year.
| Pack | Price | Cleans | Per Standard minute |
|---|---|---|---|
| 60 credits | $4.99 | 1 h Standard · 30 min Enhanced | $0.083 |
| 300 credits | $9.99 | 5 h Standard · 2.5 h Enhanced | $0.033 |
| 600 credits | $16.99 | 10 h Standard · 5 h Enhanced | $0.028 |
What a recording costs
Enhanced handles files up to 30 minutes; Standard handles up to 60.
| Recording | Standard | Enhanced |
|---|---|---|
| Voice memo, 5 minutes or less | Free | Up to 10 credits |
| 20-minute interview | 20 credits | 40 credits |
| 30-minute podcast episode | 30 credits | 60 credits |
| 50-minute lecture | 50 credits | Too long; split it or use Standard |
When a monthly plan is cheaper
A plan gives 1,200 credits every month for $16.99, but unused plan credits expire at the end of each month. Compared with the 600-credit pack, the plan only saves money if you use more than about 600 credits every month. If you clean recordings now and then, stay with packs.
Plans can be canceled anytime from Billing, and you keep the plan until the end of the period you paid for.
If something goes wrong
If a file fails to process, its credits go back to your balance automatically. You can also ask for a refund of a credit pack within 14 days of purchase, as long as none of its credits have been used. The refund policy has the details.
Common questions
Do I need a card to try it?
No. The preview needs no account and no payment, and Standard files up to 5 minutes are free to clean.
Do credits expire?
Credits from packs never expire. Credits from a monthly or yearly plan are added each month and expire at the end of that month.
Do audio and video cost the same?
Yes. Credits depend only on the length of the file and the mode you choose.
