Frequently Asked Questions
What do I get from a track?
The tempo in BPM, the time of the first beat and the time of every beat, as JSON and CSV files.
Which files and lengths does it take?
An audio file, or a video that has sound, of up to 10 minutes. A file without sound is refused, and so is one that is too short to find a beat.
How accurate is the BPM?
It is best on music with a steady, clear rhythm. It looks for a tempo between 60 and 180 BPM, so a very slow or very fast track can come back at double or half its tempo, for example 75 as 150. Speech, ambient sound and tracks that change tempo give weak results.
Can I use the beat times to edit a video?
Yes. The times are in seconds, so you can place cuts, transitions or text changes on them in any editor. AI Trailer Maker can also cut to the beat.
What does a run cost?
A run costs 1 credit. Every run costs credits and needs an account.
