Features
From speaker detection to secure delivery, every part of the workflow stays focused on usable audio.
CORE OUTPUT
AI speaker separation gives each detected speaker an independent audio track.
Every track starts at the same point and stays aligned with the original recording.
Let Seply detect speakers automatically, or enter the expected number yourself.
Use Seply with podcasts, interviews, meetings, panels, and other multi-speaker recordings.
Download individual, time-aligned WAV files for your editing workflow.
Each Seply feature has its own credit rate. See the estimated cost before processing begins.
Separation vs diarization
Speaker diarization
00:00-00:12 Speaker 1
00:12-00:19 Speaker 2
00:18-00:24 Speaker 1 + Speaker 2
Speaker diarization tells you who spoke when.
Speaker separation
AI speaker separation creates an actual track for each speaker, so you can edit, mute, enhance, or reuse every voice independently.
Use cases
Keep every voice editable, whether the final destination is an episode, research archive, meeting record, or video timeline.
Separate hosts and guests so you can adjust levels, remove mistakes, and edit each voice independently.
Isolate interviewers and participants for easier review, analysis, and speaker-specific workflows.
Turn one mixed discussion into separate tracks for review, archiving, or post-production.
Prepare independent dialogue tracks before placing them back into your video editing timeline.

Monthly plan credits expire 30 days after they are granted. One-time credit packs expire 12 calendar months after purchase. Canceling a subscription does not remove credits before their own expiration dates.
Credits reserved for a confirmed failed job are automatically returned to the original credit batches with their original expiration dates.
For new jobs, the original recording and completed speaker tracks are stored privately for 30 days from completion. You can listen in your history and download separated tracks during that period. Limited job metadata remains after media expires.
You may request a refund within 7 calendar days for purchased credits that have not been used. Used credits and completed jobs are generally not refundable. Exceptions apply for duplicate charges, failed delivery, and rights required by law.
