Regular expression for BPM to reduce decimals

Support
1

I have approximately 15,000 MP3 files with a BPM detail that, for example, has a value of 70.250000 or 70 or 138.540000.
I want to change this to 70,2 or 138,5 or 70,0.
Who can help me?

Try Convert>Tag-Tag or and action of the type "Format value" for BPM
Format string: $regexp(%bpm%,(\d+\.\d).*,$1)

Just a remark: as it is "beats per minute" you have to have a track of 5 minutes length to be 1 beat off. I doubt that anybody will notice.

Decimal values in BPM show IMHO that a human has set the beat - and that human beat is a bit irregular.
Or it shows that a track has different speeds. And then the average beats do not describe the characteristics of such a piece.
