Demixr review
A focused web tool for vocal isolation, dereverberation, and stem separation.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Demixr is an online audio-processing suite for creators, mixers, and content teams working with uploaded audio. Its core tools cover AI vocal and instrumental separation, four-stem separation, dereverberation, voice-activity detection, batch export, and musical analysis for BPM, key, and Camelot values. The service is particularly suited to vocal producers who need cleaner isolated vocal tracks, as well as users preparing stems or reviewing audio structure in a browser.
The published plans show a useful progression from limited free access to larger monthly audio allowances. Free includes 10 minutes of uploaded audio per month, queued processing, two free VAD uses, and no WAV downloads. Go costs $4 per month and adds 10 hours, priority queueing, and WAV downloads. Plus costs $9 per month for 50 hours, while Pro costs $15 per month for 100 hours; both also include priority queueing and WAV downloads. Paid plans are described as one-time payments with no auto-renewal, making the quota and payment model important to review before choosing a tier.
Demixr’s strongest distinction is the combination of separation and dereverberation with editable voice-activity markers. Those markers can support batch export, while the BPM, key, and Camelot analysis add context around the processed audio. Processing takes place through the web, and paid plans provide WAV downloads for subscribers. The trade-off is a narrow delivery model: users who need desktop software, stated integrations, or API access should choose another option. Demixr fits producers and content teams comfortable uploading audio to a browser-based service, especially when vocal cleanup and stem workflows matter more than broader platform connectivity.
