Title: Deep scan mode and algorithm improvements are needed
Post by: Artem S. Tashkinov on July 29, 2010, 12:51:44

First of all, thank you very much for this great and free software!

Several bugs and suggestions:

1) Sometimes it shows very different songs as being similar, e.g.(http://img441.imageshack.us/img441/2179/80similar.png) (http://img441.imageshack.us/i/80similar.png/).
2) Thus it would be nice if the waveform comparison algorithm was improved
3) Thus it would be nice to have an option to scan full tracks (not only the first 60 seconds)

It is already improved, see precise algorithm (3rd tab). As we can see 3rd tab show unsimilar results, it is also content based algorithm, but had very different calculation method than general (1st tab). It shows more accurate results.

You better look at both similarity columns. Songs with standard scores below 80-85% typically have precise scores below 10%. But eventually there appear completely different songs with very high precise scores (nobody is perfect), but they show low standard scores and can be easily rejected by that.
