Questions
Is it free?
Yes, always, for whole files, up to 20 a day, with no sign-up.
What do the numbers mean?
Loudness is how loud the file sounds overall: podcasts aim for about −16, and YouTube for −14. The noise floor is the level of background hiss or hum, and lower is quieter.
What happens to my files?
They stay private. Files are deleted after 24 hours, and free results after 1 hour.
