ChatGPT Tempo/Time Calculator

Years ago I created a spreadsheet to help me determine which tempos to use for clean 30 and 60 second edit points. I was toying with the idea of creating a smartphone app for it, but ChatGPT has eliminated that need. I created a video to show you how to use ChatGPT to help you with this:

alternatively, you can use this:
time(in sec) /(#beats in bar x 1/bpm x 60) = #bars
ie at bpm 96 and 4 beats per bar, how many bars needed for 30 sec edit
30sec / (4 x (1/96bpm) x 60) = 12 bars (rounded down)
with some algebraic manipulation, you can isolate for BPM if you have the other variables, but i’m not sure why you’d do that since natural reverb tails would throw things off.
it worked for some other examples i tried but let me know if you run into any errors

that's quite intersting
I use
https://toolstud.io/music/bpm.php in order to calculate the duration of my beats to be able to place markers in ms for gaming purposes
They do have a tool to calculate the length of a song based on the tempo, the bpm and the signature

Thanks for sharing this! I will save this in my toolbox of useful engineer information!

I do the same thing, I drag a looping ruler for whatever section I need, 0:15, 0:30 etc. BUT, knowing good tempos makes it easier to write music that naturally ends at the required time. You want time edits to sound natural.
