What is Cleanvoice AI?

Cleanvoice AI is an AI podcast editor for audio and video podcasts. Its editing step finds filler words and long pauses in a recording and cuts them out. A separate cleaning step strips background noise, mouth sounds and breaths, and an enhancement step works on tone, loudness and echo. The service is operated by Sigmoid Creativity S.R.L., a company incorporated under Romanian law with its registered office in Bucharest, which does business as Cleanvoice AI.

Four facts decide whether it fits most workflows. Usage is paid per processed hour, new accounts get a free allowance, uploaded files are deleted within days rather than kept as an archive, and the vendor describes the product as built for speech rather than music.

Core features

Cleanvoice groups its tools into editing, cleaning and enhancement, plus text outputs generated from the same upload.

Filler words, pauses and mouth noise

  • Filler word remover: The filler word remover cuts ums, uhs and other fillers from audio and video in more than 20 languages.
  • Language coverage: Listed languages include English, German, Romanian, French, Dutch, Spanish, Italian, Portuguese, Polish, Arabic, Turkish and Bulgarian, and detection works on how speech sounds rather than on text, which the vendor says also helps with accents and similar-sounding languages.
  • Natural gaps: When fillers are removed, the AI identifies the context of the audio and adds room-noise silence to keep the flow of the episode natural.

Noise removal and studio sound

  • Background noise removal: The enhancer targets hum, hiss, wind, traffic and fan noise, along with echo and reverb, uneven loudness, muddy or thin tone and some distortion.
  • Combined pass: Enhancement can run together with editing, so filler words, long silences, breaths and mouth sounds are cut in the same job as the noise and tone fixes.

Multitrack and video sync

  • Multitrack editing: Up to 5 tracks can be uploaded, for example one per speaker, and Cleanvoice edits them together so they stay in sync.
  • Preserve Length: For video, Preserve Length silences fillers instead of cutting them, which keeps the original duration when the audio has to stay aligned with other footage.
  • Custom templates: A template can mute or remove plosives, clean or keep click sounds, and include subtitles or leave them out.

Transcripts, summaries and show notes

  • Transcription: Audio and video can be transcribed in 99 languages.
  • Chapters: The summarizer groups related topics into chapters with chapter names and timestamps.
  • Show notes: Cleanvoice writes AI-generated show notes that highlight the important parts of an episode.

Timeline export

Edits can be exported as a timeline to Adobe Audition, Adobe Premiere, DaVinci Resolve, Reaper and Audacity, and to any editor that reads .EDL edit decision lists. Every cut comes back as a timeline that can be opened and adjusted by hand.

Guide

Cleanvoice has two working modes: a browser workflow for individual episodes and an API for batches or products.

Cleaning a recording in the web app

  1. Files can be imported from your device, Dropbox, Google Drive or a link, or recorded directly in the uploader.
  2. Keep Enhance turned on, add Clean Audio for noisy recordings, and add Edit when you want cuts such as fillers and pauses.
  3. Set Enhance Mix to control how strong the enhancement should be.
  4. For video or multitrack sessions, choose whether edits are cut or muted; Preserve Length keeps the original duration.
  5. Download the cleaned file, or export the edits as a timeline to finish the episode in your own editor.

Processing files through the API

  1. Create an account and copy the API key from the Developers dashboard.
  2. Install the official Python or JavaScript SDK, or call the REST API directly.
  3. Submit a local file or the URL of the audio or video you want to edit.
  4. Jobs run asynchronously: the SDK polls for the result automatically, or a webhook can upload the result to your S3 storage.

Cleanvoice AI use cases

The examples the vendor highlights are recordings made in poor conditions and episodes that need several cleanup jobs at once.

  • Remote interviews: A muffled or robotic Zoom call with a guest is a headline case for the enhancer, which is positioned to turn it into a professional-sounding episode.
  • Phone and street recordings: Phone recordings and clips captured while walking down a street are targeted for removal of traffic noise and chaotic background sound.
  • Video podcasts: Edits can be muted instead of cut so the audio and video stay in sync after filler words, mouth sounds and noise are removed.
  • Episode promotion: Beyond show notes and chapters, the same upload can auto-generate posts for a Facebook update, an Instagram feed post, a Tweet or other platforms.

Who is it for

Cleanvoice addresses podcasters, media agencies, businesses, audio engineers and video editors. The filler word remover is also aimed at YouTubers and video creators, course creators, coaches, journalists and teams editing interviews, webinars or presentations, while developers can run the same removal at scale through the API.

Good fit

  • Conversational shows where filler words, long pauses and mouth sounds are the main cleanup work.
  • Editors who want an automated first pass and then fine-tune cuts in Audition, Premiere, DaVinci Resolve, Reaper or Audacity.
  • Multi-speaker shows recorded on separate tracks, up to five per upload.
  • Creators who speak languages other than English, since filler removal covers 20+ languages and transcription covers 99.
  • Developers adding audio cleanup to an app or pipeline through SDKs, REST calls and webhooks.

Less suitable

  • Music production, mastering or vocal separation, which fall outside a product built for speech.
  • Restoration of badly damaged recordings with heavy clipping or missing frequencies.
  • Anyone who needs a long-term file archive, because uploads are deleted after seven days by default.

Platforms

Cleanvoice's services cover a website, a web application and APIs. No native app from the vendor turned up in the US App Store search run for this page.

  • Formats and size: WAV, MP3, M4A, FLAC, OGG, AAC, MP4, MOV and WebM are among the supported formats; there is no length limit, and with an account a file can be up to 3 GB, or 8 GB in total for a multitrack upload.
  • API input and output: The audio editing API accepts .mp3, .wav, .m4a, .flac, .mp4, .mov and .mkv files, and for video it processes the audio track and returns cleaned audio plus edit timestamps.
  • Rate limits: Standard API keys can call POST /v2/edits and POST /v2/upload 30 times per minute, against 100 per minute on enterprise keys, while polling is limited to 300 per minute on both.
  • Automation: A Make integration is available, and n8n is marked as coming soon.
  • Uptime: The service level agreement commits to commercially reasonable efforts toward at least 99.5% monthly uptime.

Pricing

Uploads can be tried without signing up, new accounts get 30 free minutes with no credit card, and further use is paid per processed hour through a subscription or pay-as-you-go credits. All plans include all features, and the listed prices exclude VAT.

Pay-as-you-go rates fall from $2.20 per hour on the 5-hour pack to $1.50 per hour on the 30-hour pack, about a third less per hour. A subscription at $11 per month buys 10 hours, twice the hours of the $11 pay-as-you-go pack, and the 100-hour plan brings the rate down to $0.90 per hour. Pay-as-you-go credits are described as flexible pricing for occasional use and stay valid for 2 years after purchase, even though each pack card also carries a "Processed Audio per Month" label. Subscription credits can be used anytime within the subscription period, and unused credits roll over up to three times the plan limit. Uploads are rounded up to the nearest minute.

Sales tax or VAT may be added depending on where you live, and companies in Europe can buy without VAT by entering a VAT ID. The pricing page title advertises plans from €10/month and a EUR/USD switch is shown, but per-tier EUR amounts and yearly-billing prices were not displayed in the default view captured on October 4, 2026. Volumes above 200 hours per month, or business customization, go through a custom plan.

The developer page lists more tiers than the main pricing page. It shows a 200-hour pay-as-you-go pack at $200, or $1.00 per hour. It also lists a 200-hours-per-month subscription at $175 per month, or $0.88 per hour. For more than 200 hours, custom pricing on that page starts from $0.20 per hour. Startups can request up to 200 hours of free API credit from the dashboard. The request form only appears while an account holds less than one hour of credit, and each account can apply once.

Renewal, cancellation and refunds

Paid subscriptions are billed in advance and renew automatically until cancelled. Cancellation takes effect at the end of the current billing period and does not affect fees already due or paid. Fees, subscription payments and credit purchases are final and non-refundable unless the law requires otherwise or Cleanvoice agrees in writing, and no refund is given for partially used periods or unused credits.

Cleanvoice AI alternatives

Descript, Adobe Podcast and Auphonic appear as alternatives in third-party comparisons of podcast cleanup tools, and each overlaps with a different part of Cleanvoice.

  • Descript: Descript describes itself as a collaborative editor that works like a doc. Its filler tool can purge "ums," "uhs," "you knows" and a dozen other filler words with a click. That suits people who want to cut inside one document-style editor; Cleanvoice instead processes the file and hands back audio, video or a timeline for another editor.
  • Adobe Podcast Enhance Speech: Adobe offers Enhance Speech as a free AI filter for cleaning up spoken audio. Its premium tier allows enhancement of up to 4 hours a day, with files up to 2 hours long and 1 GB in size. Cleanvoice pitches its speech enhancement as like Adobe Podcast Enhance but via API, with loudness normalization, level balancing across speakers, EQ and dereverb.
  • Auphonic: Auphonic is free for 2 hours of processed audio per month. It also lists cutting filler words, coughs and silence among its features. Cleanvoice's free allowance is 30 minutes for new accounts, so Auphonic offers more free processing for small monthly volumes.

Limitations

Product limits

  • Speech only: Cleanvoice is built for speech; Keep Music protects music you want to keep in a recording, but the product is not a tool for mastering songs or separating vocals from a track.
  • Damaged audio: Badly damaged audio, such as recordings with heavy clipping or missing frequencies, cannot be fully restored.
  • Over-editing: Removing every filler can make speech sound clipped, and on video the cuts become jump cuts unless Preserve Length is on.
  • No accuracy guarantee: Under its terms, Cleanvoice does not warrant that results will be accurate, complete, error-free or suitable for any particular purpose.
  • Changing free offers: Free plans, trials and free usage allowances can be modified, suspended or discontinued at any time.

Data handling, privacy and rights

Files auto-delete after 7 days by default, and deletion the moment a job finishes is offered as an option. The terms set the outer limit: uploaded content and results are automatically and permanently deleted no later than seven days after processing completes or fails, or after an upload that was never processed. Content can be kept longer only where strictly necessary, for example to investigate a reported technical issue or a failed job, to meet a legal obligation, or to defend legal claims. Guest uploads made without an account are deleted no later than four hours after upload, unless the service says otherwise.

You keep all rights, including intellectual property rights, in the content you upload. Subject to applicable law you also keep the rights to the results, and Cleanvoice does not claim ownership of them. The terms say Cleanvoice will not use your content or results for any purpose other than providing the services you requested, except where law or a competent authority strictly requires it. On model training, the developer page states "No Training on Your Data" and says Cleanvoice records its own dataset in professional studios. Processing can still involve third-party providers, including cloud infrastructure, hosting and artificial intelligence providers.

Cleanvoice advertises GDPR compliance, EU data storage and ISO 27001 certification. Its data processing agreement also allows client personal data to be transferred to and processed in locations outside the EU/EEA as needed to provide the services, so EU storage and processing location are separate questions.
