How credits work
Each audit runs the checks you choose on every file you upload. 1 credit = 1 check on 1 file. Re-auditing unchanged files costs only 0.2 credits per check.
Speaker Consistency
Compare speaker identity across all tracks
1 credit / file
Audio Quality
Detect noise, clipping, artifacts, and bandwidth issues
1 credit / file
