What does AI Voice Isolator do?
Seply Voice Isolator reduces background noise in speech recordings. Use it to clean up podcasts, interviews, voiceovers and meeting audio.
Can it separate different speakers?
Voice Isolator cleans the background around a conversation. For a separate audio track for each person, use Speaker Separation.
Will it remove every noise or repair distortion?
Results depend on the recording. Very loud noise, clipped or distorted audio, and overlapping voices can still affect clarity. Preview the result before using it; complete noise removal is not guaranteed.
Which formats can I upload? Does it accept video?
Supported audio formats: AAC, AIFF, OGG, MP3, OPUS, WAV, FLAC, M4A. Video files are not accepted. Export the audio track from your video editor before uploading.
How large or long can a recording be?
Each audio file can be up to 500 MB and 60 minutes long. Both limits apply independently.
Can I leave the page while it processes?
Yes, after uploading and submitting the recording. Processing continues in the background; open the task from your dashboard history to check progress or listen to the result.
Are recordings private, and how long are they available?
Original and cleaned audio use private storage with access restricted to the account that created the task. They are accessible for 30 days. Download your result before that window ends.
Who can use it today, and what does it cost?
Signed-in users can process audio for 10 credits per minute, with a minimum of 10 credits. Credits are reserved before upload, then adjusted to the verified audio duration. Failed or canceled jobs are refunded.
