Voice Isolator
A browser-based AI tool that reduces background noise and extracts clearer vocals from six common audio formats.
About Voice Isolator
Voice Isolator is a browser-based AI audio tool that separates a voice from background noise and mixed sound. Upload an audio file, let the service process frequency patterns and acoustic signatures, then download the isolated vocal output. Support for MP3, WAV, M4A, AAC, FLAC, and OGG covers common podcast, video, interview, and music workflows. The service targets traffic, crowd, wind, air-conditioning, echo, environmental sound, and background music while preserving vocal clarity. New signed-in users receive 60 free credits, and processing consumes one credit per second of audio. Paid options provide larger allocations: Starter includes 2,000 credits per month, Pro includes 6,000 credits per month, and One-Time includes 500 credits valid for one month. This upload-process-download flow suits occasional cleanup, but credit use rises directly with recording length, and the one-time credits expire after a month. Complex mixes can produce variable results, so important material benefits from comparing the site's before-and-after samples and reviewing each processed file before production use.
Best for
Best use cases
A field interview contains traffic, wind, or crowd noise that competes with the speaker's voice.
A podcast recording includes persistent room noise or air conditioning that needs cleanup before editing.
A mixed music or video file needs an isolated vocal output for a new production or backing-track workflow.
Compare before choosing
The browser upload-process-download flow is simpler than configuring a full digital audio workstation for a single cleanup task.
Usage is credit-based at one credit per processed second, so long recordings can cost more than short clips.
Support for six common audio formats makes conversion less likely, although results still depend on the complexity of the source mix.
Features
Podcast cleanup
Reduce ambient room, traffic, or air-conditioning noise in spoken podcast recordings before editing and publishing.

Isolate speech from crowd, wind, echo, and other environmental sounds in field or remote interview recordings.
Music and video vocals

Pros
- The browser-based upload and download workflow avoids setup in a full audio editing application.
- Support for MP3, WAV, M4A, AAC, FLAC, and OGG reduces the need to convert common source files.
- Sixty free credits let signed-in users test short clips before buying a larger credit allocation.
Cons
- Each processed second consumes one credit, so long recordings deplete an allocation faster than short clips.
- The One-Time pack's 500 credits remain valid for only one month, which limits value for infrequent use.
- Voice separation quality depends on the source mix, making a review step important for complex music or noisy recordings.
