Hi guys, I have another idea: Do you think it could be a good idea insert a bpm calculator and a delay calculator? Other calculators?
I'm sorry, I'm not able to program otherwise I could help you with the wavosaur :-p

7. Tempo Calculator

This would be REALLY useful for working with loops; I don’t know why so few editors have it. What I mean is: you select part of the audiofile, tell Wavosaur how many beats are in that part, and Wavosaur automatically calculates the tempo in bpm

I m definitely agree with you. :)
But, sorry, could you detail me a little more the feature you want?

Is it a simple dialog (or other) with a simple formula to deduce the bpm with the selection lenght and the sample rate (and other paameters).

Or is it a bpm finder: you open your wav and an algorithm deduce itself the average value of the tempo.

Thanks to describe me a little bit more.

Note that I very like this idea, for the second one I described, it must take more job, and I have to plan all that.

Yes.

No.

Obviously I can't speak for federgast or anyone else; what I had in mind was:

1. highlight/select a section of the audio file
2. select "BPM Calculator" from the Tools menu
3. a dialogue box appears asking you to "Enter number of beats"
4. when you do so, Wavosaur tells you the tempo of the section in bpm.

...So for a two-bar drum loop in 4/4 you highlight the two bars, select "Tools > BPM Calculator", type "8", and Wavosaur tells you the tempo of the loop in bpm.

The maths is pretty straightforward, I know, but it'd be a real time saver :)

Ultimately, you could integrate it with the file menu, too. So once Wavosaur has calculated the tempo for you, you can tell it to add this information to the file, either as metadata or by simply adding it to the filename (i.e. if the tempo is 94 bpm, Wavosaur gives you the option of adding "_094" to the end of the filename).

But, erm, one thing at a time, you know...Wink

Very Happy

Beat number... do you mean that the user should the "number of beats" in the selection?

Beat duration? Does that mean the length of the selection or the length of each beat.

- Select a file part
- Open the dialog box
- By default the beat number is 4 or the previous you entered.
- The bpm is displayed

The beat duration is simply the duration of 1 beat: if you entered 4 beats in 1 selection, then the beat duration is "selection time"/4.
