Wishlist / Other Comparison Criteria
« on: July 13, 2010, 10:29:33 »
SNR feature could be extended:
Quality measure by frequency (band) content.
Rather often potentially high quality recordings (e.g. 192 KBit/s MP3) turn out to be just recompressions of e.g. 128 kBit/s material. Of course frequencies (or other details) lost at previous compressions can't be regained by that.

But besides that: This software is rather helpful since it does local comparison on a track to track basis and doesn't rely on a server database with entries of acoustic fingerprint vs. tags.

General / save

A possible workaround is not to shut down your computer but to switch to hibernate / power saving or whatever that is called in your OS. In Win7 it was even possible for me to pause scanning and to proceed from that point after restarting Windows.

Bugs / Performcence issues

My recommendation is to put more emphasis on *duration*. To look for music that starts the same but is different in length is maybe a nice feature but of no interest for 99% of users searching typically for real duplicates. By leaving that feature e.g. as an option and concentrating on files with approximatly the same duration would dramatically reduce search space and boost performance for larger collections. There's no additional cost since you compute track duration anyway and that's only done once per track -> O(N) and not per comparison -> O(N square).

Wishlist / Dont show duplicates under xx% similarity

No, it doesn't.
It only filters out groups with *all* entries below that threshold.
Maybe that's not perfect but it's better than nothing.

Bugs / "Copy All" in tag editor

The "apply" button only acts on the entry of the group which you selected at the beginning by "edit tags (CTRL-E)". The other entries you click thereafter can only be used as source of tag entries but not as target. This applies not only to "copy all" but also for "copying" single entries by clicking on the blue header above the field.
Try that.

Bugs / false 100% similarity

It's not only a problem of long durations: Having two files of e.g. 2 minutes with high similarity score and differing by 10 secs is a strong indication of corruption.
I actually use that for identifying corrupted files but at the moment it has to be done "manually" by looking for significant duration mismatches in high score groups.
