CleanTake vs ACX Check
ACX Check tells you whether a file meets Audible's RMS, peak and noise rules. CleanTake runs the same checks and also checks the words against the script, so one report covers both.
ACX Check is the free Audacity plugin that tests a file against Audible's audio rules. Price: free.
| CleanTake | ACX Check | |
|---|---|---|

| Clipping spots with times | Yes | No |
| Word check against the script | Yes | No |
