Originally published on my blog.

The short answer: If you want an all-in-one editor with transcript-based editing and you don't mind uploading your files plus paying a subscription, Descript's Studio Sound (from $16/month) is the polished choice. If all you need is noise removal — no uploads, no subscription, $0 forever — CleanTake does that job locally on your own machine.
No "one is better" verdict here. Different tools for different priorities. Below is everything we could verify, including one thing we couldn't.

What each tool actually is

Descript Studio Sound is one feature inside Descript, a full AI-powered audio/video editor. Its official description: "Instantly improve audio quality of any recording with one click – remove background noise, enhance speech, and get studio-quality sound without a professional setup." Around it sits transcript-based editing, Overdub voice cloning, auto-captions, and stock media — a whole production suite used by 6M+ creators.

CleanTake is a free, open-source tool that does exactly one job: take a noisy recording in, give you the same file back with clean audio. No editor, no transcript, no timeline. It runs 100% on your machine — DeepFilterNet for noise removal, loudness leveled to −16 LUFS — and nothing is ever uploaded anywhere.
The honest comparison

CleanTake
Descript Studio Sound
Price
$0 forever (open-source)
Free plan (limited) → Hobbyist $16/mo → Creator $24/mo → Business $50/mo (annual billing; monthly costs more). Prices checked on descript.com, Oct 4, 2026.
Privacy / upload
100% local. Your files never leave your machine.
Cloud processing. Your media is uploaded to Descript's servers — inherent to how Studio Sound works.
Workflow
Drop file in → same file out, audio cleaned. One job.
Full editor: edit via transcript, captions, Overdub, stock media. Whole production pipeline.
Audio output
DeepFilterNet denoise + loudness normalized to −16 LUFS. Verified numbers, tested on real recordings.
We could not test this — see below.
Usage caps
None. Process as much as you want.
Capped: 1–40 media hours/month and 100–1,500 AI credits depending on plan.
Video handling
Video stream copied bit-for-bit — zero quality loss; only the audio track is replaced.
Full video editor; 4K export on Creator plan and up.
Honest limits
Removes steady environmental noise (fan hum, AC). Won't fix clipped/distorted audio; can't separate overlapping voices.
We don't know its failure modes firsthand — we couldn't run it.

Price, spelled out

Descript's pricing (per person, from descript.com/pricing, checked October 4, 2026):
-Free — $0: 1 media hour/month, 100 one-time AI credits, Studio Sound in "Limited" form, 720p watermarked exports.
-Hobbyist — $16/mo billed annually ($24/mo monthly): 10 media hours/month, 400 AI credits/month, 1080p watermark-free, Studio Sound included.
-Creator — $24/mo billed annually ($35/mo monthly): 30 media hours/month, 800 AI credits/month, 4K export, full Studio Sound. Marked "Most Popular."
-Business — $50/mo billed annually ($65/mo monthly): 40 media hours/month, 1,500 AI credits/month, team features.

So the cheapest way to get full Studio Sound is $16/month paid yearly — $192/year. CleanTake is $0, which over three years is a $576 difference for the noise-removal job alone.

Privacy and upload: the real fork in the road
This is the actual decision point, more than price.
Descript is a cloud product. When you use Studio Sound, your audio goes to Descript's servers for processing. For most creators that's a non-issue — but if you record client calls, unreleased work, medical or legal content, or you simply don't like your raw takes sitting on someone else's infrastructure, it's a real consideration.
CleanTake was built for the opposite trade: your files never leave your disk. There's no account, no upload queue, no retention policy to read — because there's no server involved at all.

Workflow: one job vs. the whole studio
Ask yourself what you're actually trying to do:

"I recorded a voiceover/screen recording and the fan hum is ruining it" → that's a one-job problem. CleanTake: drop the mp4 in, get the same mp4 back with clean audio. Done in seconds.
"I'm producing a podcast/video series and I live in editing" → that's a suite problem. Descript's transcript editing alone (cut audio by deleting text) is a genuine superpower for long-form work, and Studio Sound rides along inside it.
Buying a full editing suite to remove fan noise is like buying a car to charge your phone. But if you're already driving the car, the phone charger in the dashboard is great.
What we couldn't test (saying it plainly)
We don't have a Descript account and our budget for this comparison was $0 the same $0 CleanTake costs. So we could not run Studio Sound on our test recordings and we will not invent an A/B result.
Everything in the table above about Descript comes from their official pricing page and feature descriptions, checked October 4, 2026. Everything about CleanTake comes from our own code and test runs.

Who should use which
Use Descript Studio Sound if: you want the full editor anyway (transcript editing, captions, Overdub), you publish often enough to justify $16+/month, and cloud upload doesn't bother you.
Use CleanTake if: you only need noise removal, you want zero uploads, you hate subscriptions, or you process hours of audio and don't want to watch a credit meter.
Use both if: you edit in Descript but pre-clean sensitive takes locally first. Nobody said it has to be a rivalry.

FAQ
Is there a free alternative to Descript Studio Sound?
Yes. CleanTake is free and open-source, runs 100% locally, and handles the core job — removing background noise from voice recordings. Descript's own free plan also includes Studio Sound in "Limited" form (1 media hour/month).
Does Descript Studio Sound upload my audio?
Yes. Descript processes media in its cloud, which is inherent to how Studio Sound works. If your workflow requires zero uploads, a local tool like CleanTake is the alternative.
How much does Descript Studio Sound cost?
Full Studio Sound starts at the Hobbyist plan: $16/month billed annually ($24 month-to-month), per descript.com pricing checked October 4, 2026. The free plan includes a limited version.
Can CleanTake replace Descript?

Free local audio denoiser: clean voice recordings without uploading

Description: "CleanTake removes steady room noise from voice recordings on your own computer — no upload, no account. Real before/after test (25 s) and the exact method."

Originally published on my blog.
CleanTake removes steady room noise — fan, air-conditioner hum — from recorded voice files, entirely on your computer. No upload, no account, no subscription. On a real 25-second recording tested September 28, 2026, it cut environmental noise by about 32 dB while the voice stayed intact. It cannot separate overlapping voices, and since October 2, 2026, there's a free public download — a portable ZIP or one-click installer for Windows.

Does it actually work? Listen to the same 25 seconds, before and after
One take, one voice, recorded in a room with a fan running. The before file is the raw recording. The after file is the same take cleaned by the CleanTake pipeline. Listen to the steady hum underneath the voice in the first clip, and how much of it survives in the second.
🎧 Before — raw recording (MP3)
🎧 After — cleaned (MP3)
Noise type: fan / air-con hum · Test 2026-09-28, re-checked 2026-09-30 · Engine DeepFilterNet 0.5.6 · ffmpeg 8.1.2 · 25.0 s each · Linux CPU (public build targets Windows)
What to listen for: in the before clip, the hum sits behind the voice at a near-constant level — it never pauses. In the after clip, the voice keeps its tone and pacing, but the hum drops out of the pauses between sentences. Nothing was re-recorded, re-acted, or sweetened.
What kind of noise does it remove — and what can't it do?
It handles:
Steady room noise: fans, air-conditioners, electrical hum
Hiss from cheap microphones and interfaces
Voice recordings where the speaker is the only voice
It can't do (yet):
Overlapping voices. In a café-style test with four people talking over each other, it reduced everything evenly — voice included. It does not separate one voice from a crowd.
Real-time calls. It processes recorded files, not live audio. It is not a Krisp replacement for Zoom.
Music. It is tuned for speech; singing and instruments are not its job.
The honest version is the short one: CleanTake is a cleaner for environmental noise, not a separator for human noise. If your problem is a noisy room and a single speaker, that's exactly the case it passed. Everything else is on the limits page, including the failed café test.
Why clean audio locally instead of using a free online tool?
Free options exist, but they each cost something that isn't money. Checked September 30, 2026:

The pattern: cloud tools gate downloads behind sign-ins and daily limits; open-source repos work but demand a terminal. CleanTake's bet is the gap in the middle — proof-first page, one-click installer, your files never leaving the room.
How was this tested? Exact method, versions, and numbers
No cherry-picking claims without a method. Here is everything needed to reproduce the result:
Source: a real 25.0-second voice recording in a room with fan/air-con hum (MP3, 400 KB, 48 kHz mono). Not synthesized, not re-recorded.
Pipeline: ffmpeg → DeepFilterNet 0.5.6 → loudness normalize to −16 LUFS (I=−16, TP=−1.5, LRA=11). Output: MP3, 601 KB.
Result: environmental noise reduced by ≈32 dB, voice preserved — measured on this sample, 2026-09-28. Your mileage varies with the room.
Speed: the full pipeline processed this 25-second clip in about 5 seconds on a standard CPU with no GPU (timed 2026-09-30, Linux test machine).
Re-check 2026-09-30: an independent measurement of the noise floor in two speech pauses showed the floor dropping from −33.0 dB to −51.1/−59.3 dB — an 18–26 dB reduction under a different, stricter metric. Both are published so you can see the method matters.
Voice preservation: a listening assessment (the voice sounds the same), not a lab metric — labeled as such.
Who is this for — and who should skip it?
Podcasters and voiceover folks recording at home with untreated rooms — fan and AC noise is the single most common complaint.
Anyone shipping voice notes, course audio, or narration who wants a free local option without uploading client audio to a server.
Skip it if your audio has multiple people talking over each other, or you need real-time noise removal on live calls.
