estimated BPM are way different than the manual
Hi,
I had the BPM estimated on a blues album. All the songs were estimated to be between 65 and 132. One was high peak with 199 and totally impossible. I did it manual and had a result of 100? Another song I did of that album to double check was manual 70 instead of 80!?
Why is it not working accurate?
thanks,
Christian

Hi Christian,
unfortunately, BPM detection isn't an accurate science - there are always some wrong values. Most often, values are doubled or halved (like in your 199/100 case), sometimes - admittedly - they are completely off.
When analyzing with beaTunes I recommend using the Rayshoot algorithm and pre-choosing a BPM range. For Blues a 70-140 range is probably a good choice.
Hope this explains a little..

Thanks Hendrik!
hmm I thought it would be more accurate. So now I have to doulbe check everything and do it manual anyway!? I did use the Rayshoot algorithm and have pre choosen the range, but it was still off! I bought the software mainly to get all the BPM into itunes, second to get everything more organized. But this is a little of a bummer that this can be that off! I had the trial version and saw that it was off. I thought maybe when I buy the programm it might be better and more accurate. But now I have the problem that I have to double check everything, because everything is such close with the BPM to each other even 20 off is a lot!

I made this exact comment about a year ago. It's a real puzzle why Mixmeister BPM analyser on the PC can get the BPM calculation correct 99.9% of the time without any selections of various ranges or algorithms and yet BeaTunes FAILS about 75% of the time. Extremely disappointing since as a DJ this is perhaps one of the most important features of this app.
And no, I don't have access to a windows machine. And even if I did, the BPM tagging from the Mixmeister app to Beatunes (or any other mac app) is not compatible.
I really hope you manage to improve this feature Hendrik!

I will definitely work on the BPM algorithm for beaTunes 3.
That said, I can guarantee that MixMeister is not right 99.9% of the time and also that beaTunes does not fail 75% of the time. Let's keep the numbers real.
Regarding MixMeister tagging - the last version I tested did not tag in accordance to the id3 standard - not sure whether they fixed that issue.
