... we think variant B can be archived simply by 100% slider in options dialog.

With this you mean that right now it can be achieved by moving the bar to 100%, or that you would implement it this way so 100% will mean exact match including amplification?

My suggestion here is to leave the original "precise" slider bar as it is, modifying only the acoustic similarity. Then add a new slider bar activated by a CheckBox that will allow you to set the percentage of amplification similarity separately.

Finally, thanks a lot for the help and quick answer to my previous post. :)

Thanks for your message,
yes current version requires min 30 sec of sound duration, we introduce changes in comparing algorithm in next version, like change compare length.
And yes current implementation completely ignores amplification level, we think variant B can be archived simply by 100% slider in options dialog.

Hi,

I read in the help that precise only works for songs longer than 1 minute. And I am wondering if it could be possible to add the precise content comparison (with acoustic fingerprint), for short audio samples too.

My goal is to be able to compare thousands of OGG audios that range from 1 to 30 seconds max. For that, this tool will prove to be very useful if the acoustinc fingerprint could work with such short audio samples.

Here is my nightmare scenario:
  • I have 15,000 OGG audios in folder A, and another 15,000 OGG audios in folder B.
  • The content of the audios is voice.
  • The duration ranges from 1 to 30 seconds approx.

Now imagine I have to verify that all 15,000 audios are really the same. Of course since the compression is different, binary comparison is not possible... Therefore I only have left the acoustic fingerprint. But then I understand that the fingerprint measures acoustics, but not if the audio has the same levels.

Would acoustic fingerprint work for such scenario?
Would it be also possible to have two options of acoustic compare?
  • A would be "acoustic only"
  • B would be "acoustic and same amplification levels" (exact match)

Thanks, I understand these would be really complicated requests. But I have to try! :D

Carlos
