Your recordings and permission
Use StemVocal only for recordings you own or have permission to upload, process and use. Obtain any consent needed from recorded people. Uploading a recording does not transfer its ownership to us or grant you additional rights in someone else’s material. You authorize us and our processing providers to store and process your upload solely to provide the requested service and operate it securely. Do not submit illegal content, attempt to access another user’s files or evade service limits.
Transcription and review
Automatic speech recognition can omit words, add incorrect words or mislabel speakers. Review transcripts against the recording before relying on them. StemVocal does not certify transcripts, identify speakers, provide legal or medical advice, or guarantee a particular accuracy. Speaker labels are editable estimates. Subtitles retain the recording’s timeline; corrections may require a final timing check in your video editor. The service does not download from YouTube or third-party media links.
Free jobs, packs and Unlimited
The shared StemVocal allowance provides two free jobs per UTC day. A free transcription file can be up to 30 minutes / 1 GB. Free jobs run in our cloud by default and continue in your browser when the free cloud allowance is unavailable or a request is outside the free cloud limits. Free cloud transcription covers single recordings up to 30 minutes without speaker labels. In the browser, keep the tab open until it finishes; a cached model download, browser codec support and sufficient device memory are required, and speed and accuracy vary. Paid processing adds speaker grouping, files up to three hours and cloud batches. Automated or bulk use of free processing is not permitted. The audio transcription, video transcription and music separation sites share that allowance. Free jobs do not use purchased credits. Playback, editing and downloads of an existing result do not start a new job.
Translation of a finished paid transcript is included with its credits or Unlimited: English into Spanish, French, German, Portuguese, Italian, Dutch, Russian, Ukrainian, Polish, Turkish, Indonesian, Vietnamese, Japanese, Korean or Chinese, or any of those into English, up to three languages per transcript. It is machine translation and can be wrong; review it before use. Paid processing requires purchased credits or an active paid Unlimited period. It starts only when you choose the paid transcription action; free jobs never spend credits automatically. One credit covers each started 30 minutes; a 31-minute file uses two credits. Paid files can be up to three hours, and all transcription uploads have a 1 GB limit. The processor verifies duration. Two paid jobs can be active per account. The estimate is reserved first. When processing verifies the actual duration, any surplus reserved units are returned before the final cost is spent. Credits are spent when a valid transcript is ready. Failed or timed-out jobs return their reserved credits to the original grant, subject to its original expiry, refund adjustments and holds. A transcript with no detected speech is a completed processing job. A cloud batch of up to 20 files processes each file as its own job under these same terms, two at a time.
Purchases and subscriptions
Prices are shown in US dollars before applicable tax. Checkout shows the final amount. Pack credits do not expire. Unlimited renews monthly until canceled and covers music separation and audio/video transcription without a daily or monthly file-count limit. It uses no pack credits. The three-hour / 1 GB transcription limits and two simultaneous jobs still apply, subject to service capacity. Personal use only; automated bulk processing, resale and account sharing are not included. Existing monthly credit plans retain their original price, allowance and expiry. Cancel a subscription through your account’s payment portal. Cancellation stops future renewal and keeps Unlimited active through the paid period. Pending refunds or disputes hold Unlimited access; a full refund or lost dispute ends the affected paid period. A completed partial refund does not shorten it. Existing credit packs work across StemVocal. Our music separator uses one credit per separation, subject to its separate file limits.
The monthly Transcription plan adds 60 credits for audio and video transcription for each paid billing period and renews until canceled. That covers up to 30 hours: each file still rounds up to the next 30 minutes, so a 31-minute file uses two credits. Plan credits cannot be used for music separation, are used before pack credits, and expire at the end of their billing period; unused credits do not roll over. Pack credits and Unlimited work across StemVocal. You can hold the Transcription plan alongside the separate Music plan from our music site, but not alongside Unlimited or another subscription that covers transcription.
Stripe hosts checkout and payment management. No signup is required before payment. Credits become available in the checkout browser once payment is confirmed. Use the checkout email to restore purchases on another device. Contact help@acapellaextractor.com about a purchase or processing problem. Any rights to refunds or remedies required by applicable law are unaffected by these terms.
Available monthly plan changes are reviewed and confirmed in your account, then start at the next renewal without an immediate charge or proration. Existing credits keep their expiry. Retired plans cannot be selected again after switching away. You can remove a pending change with Keep current plan. With a change pending, Cancel renewal removes it before opening Stripe for your final cancellation confirmation.
Availability and keeping your work
Capacity limits can temporarily pause new jobs. Uploaded recordings and results are available for 24 hours; download the work you want to keep. The service is not a permanent archive. Local edits are saved on the current device when browser storage is available, and clearing that storage removes them. See the privacy policy for retention and deletion details. We may update the service and these terms; the current terms apply to new use and do not remove rights already attached to completed purchases.
