Oh yeah I didn't look at forum I just started to help. but I know from a long old post that rusty said they made mmw use an very good rythum to analysis the music and it will take longer.

Various, flac, mp3, m4a, ogg. It does it with all files that i do volume analysis. Its definitely not that files, it is mm. I am doing a comparison with mm, j river and foobar. Because i have tried and tested with all those apps. Which is why i am asking in "news and other stuff" I am not looking for "help" i am wondering what is the reason mm is so slow compared to those 2 apps for example.

What format of song files do you have. I have ogg files.

I have tried that in comparison it is very slow. Which is why i am asking, maybe the devs have a reason for that?

Mmw does it in idle priority. Right click on the status bar for the analysis and put it into the normal priority.
it won't stay there so do it every time.

Why is mediamonkey's volume analysis so slow compared to other popular software (i.e Foobar, J River media Centre)?

I have the paid version of mm and under options volume analysis is set to all, but in comparison to foobar for example i could do a scan on about 50+ songs (if not more) than what mm does with 10 to 15 songs. Is there a reason why it is like that?
