Somuno vs Descript Studio Sound: a full editor or a cleanup app?

Hongyang Jin · November 7, 2026 · 8 min read

Descript and Somuno aren't the same kind of product. Descript is a full audio and video editor where you edit by editing the transcript, and Studio Sound is one of its AI tools: an effect that reduces background noise and echo in voices. Somuno is a Mac app that does only the cleanup. It removes noise and reverb from voices in audio and video files on your own Mac, and leaves the editing to whatever you already use.

Choose Descript if you want to edit your podcast or video in it anyway: Studio Sound is one click away, and a Descript plan also pays for the editor, transcription and many other AI tools. It also runs on Windows and in a web browser. Choose Somuno if you already have an editor and just need cleaner voices, if your recordings should stay on your Mac, or if you want to clean many files at once for a one-time price instead of a monthly plan. We haven't run listening tests of Studio Sound, so try both on the same recording.

Somuno and Descript at a glance

Descript is an editor; Somuno is one step

Descript is where you record, edit and export a whole episode or video. You edit the transcript and the media follows, and the paid plans add a long list of AI tools – the Creator plan advertises “20+ more AI tools”. Studio Sound is one of them. You turn it on in the Properties panel for a file or layer, set its Intensity, and can even switch it on while recording. Descript says it works at the file level and “affects every instance of that file across your project”.

Somuno doesn't edit, transcribe or mix. It's a standalone app, not a plugin: you give it files, and it gives you cleaned files back, which you then use in Descript, Final Cut Pro, Premiere, a DAW or anywhere else. If you're happy editing in Descript, you probably don't need a separate cleanup app. If you edit somewhere else, paying for Descript just for Studio Sound makes less sense.

How Studio Sound is priced

Studio Sound comes with Descript's plans, and as of November 2026 it's metered in two ways:

• Plans: Hobbyist is US$16 per person per month billed yearly, or US$24 billed monthly, and lists “AI tools including Studio Sound”. Creator is US$24 or US$35, Business US$50 or US$65, and Enterprise has custom pricing.
• Media hours: 10, 30 or 40 a month on Hobbyist, Creator and Business. The free plan has 1 media hour a month.
• AI credits: 400, 800 or 1,500 a month. Studio Sound uses them: “Cost scales with the size of the job”, up to 30 credits per file. Unused media minutes and AI credits don't roll over. The free plan has 100 AI credits, once.

The free plan also exports at 720p with a watermark. Somuno costs US$19.99 once on the Somuno website, for up to 3 Macs you own or use, with a 30-day money-back guarantee, or an in-app purchase in the Mac App Store version, priced by Apple. There are no hours or credits to track. The free version enhances the first 60 seconds of each file.

On price alone, a year of Hobbyist billed yearly is US$192. But if you use Descript's editor and its other tools, you're paying for far more than cleanup, so the numbers aren't like for like.

Where your audio goes

Descript's help center says Studio Sound “requires an internet connection”, and its system requirements say “Descript uses cloud storage”. Somuno runs an AI speech-enhancement model on your Mac's GPU. Recordings are never uploaded, no account is needed, and it works offline – on a plane, on location or on a network that blocks uploads.

For confidential interviews, unreleased episodes or research recordings, check what your organization allows before uploading anything to any service.

Video: edit in Descript, or replace the soundtrack

Descript imports MP4, M4V, MOV, WEBM and MKV video (ProRes needs Creator or above), and you edit and export the video inside Descript. Somuno handles video differently: for MP4, MOV and M4V files, it replaces only the soundtrack and copies the picture as is, without re-encoding. You get the same video back with a cleaner voice. Somuno doesn't open WEBM or MKV, and it doesn't cut or edit the picture.

On audio formats, both open WAV, AIFF, FLAC, MP3 and AAC. Descript also opens OPUS but lists the Apple Lossless (ALAC) codec as unsupported, while Somuno opens Apple Lossless. More in how to clean up the audio in a video.

Cleaning many files at once

We found no dedicated batch tool in Descript's help center: you apply Studio Sound to each file or layer in a project. Somuno is built around a queue, in the free version too. Drop in files or whole folders, and each result is saved next to its original, or in a folder you choose, with “-enhanced” added to the name, so nothing is overwritten. See how to clean up a whole folder of recordings.

What each one does to the voice

Descript describes Studio Sound as an effect that “enhances spoken voice by reducing background noise, echo, and other distractions”, and its marketing says it “isolates your audio, then regenerates it”. Its help center notes that it “only works on recorded audio, not AI-generated speech”, and that if a noisy recording goes silent, you should lower Intensity or turn it off.

Somuno's model handles background noise and hum, room reverb, clipping, missing high frequencies, codec artifacts, dropouts and low-quality microphones in one pass. You choose General Model or Keep Laughter, and Strength (0–100 %) mixes the original back in. Here is Somuno's output on a phone video with noise around the speaker, default settings, level-matched. This is Somuno's result only. We haven't processed this clip with Descript.

Who should use which

You can also use both: clean files in Somuno, then import them into Descript to edit. If you do, leave Studio Sound off for those files. Stacking two cleanup passes often makes a voice sound thin.

How to compare them on your own recording

1. Pick a recording with the noise or echo you care about and export a one-minute clip, as WAV if you can. Somuno's free version enhances the first 60 seconds.
2. Process it in Somuno with default settings. In Descript, add the same clip, turn on Studio Sound at its default Intensity, and export the result.
3. Match the loudness of the two results, then listen on headphones.
4. Listen to the pauses, the consonants and the word endings. If either sounds over-processed, lower Strength in Somuno or Intensity in Descript and try again.

Whichever you pick, start with a good recording: close to the mic, in a soft room, with a few seconds of room tone, saved as a lossless file. You can also hear more examples in the before-and-after samples or read Somuno vs Adobe Podcast.
