Beats per Minute (BPM)

[ewowi]

Hi Phil,
I am using exiftool as pre-processing tool for video editing and would like it a lot if it can also calculate / detect beats per minute from mp3 files as that can determines cllp changes. What would even be more nice if it can generate a file with all the beat markers, or with every 4 beats as markers (4 = parameter), e.g. showing a list of milliseconds indicating all the beats. This file then can be used to import in a video editor (I will use perl to make sure it fits the project file of the video editor).
Is this within the feature set exiftool would like to cover?
Kind regards,
Ewoud

Hi Ewoud,

Could you send me a (hopefully small) sample file with beat markers so I can see what you are talking about?  My email is philharvey66 at gmail.com

Hi Ewoud,

You sent a link to an application that seems to parse the audio to determine the beat times.  ExifTool only works with metadata, not audio/video/image data.  So I don't think that it can do what you request.

Hi Phil,
I understand it was a little bit of an exotic question as indeed its another way of looking at a file.
And you nee to avoid scope creep. I only hoped it was a desire you already had in mind.
I will try to solve it differently.
Thx!
Regards,
Ewoud
