Various software submits acoustids so depending on how it's set up and what the user selects or what their existing data is, incorrect acoustids can end up attached. Although I'd say if there's been a lot of submissions the right recording tends to have many more. Having said which... Sometimes two (or more) recordings will have one acoustid. These are usually really similar mixes. Vice versa one recording can have multiple acoustids because for example the speed has changed between released versions or one is truncated in a way we consider to be insufficient to treat as two different recordings. --f46d04448167728ce20515e8b099 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable <p dir=3D"ltr"><br> On 12 May 2015 21:22, "Andre Wiethoff" <<a href=3D"mailto:brai= [email protected]">[email protected]</a>> wrote:<br> ><br> ...<br> ><br> > Something completely different: It seems that some audio fingerprints<= br> > are misdetected (meaning that one fingerprint has a bunch of results<b= r> > with high score, but not all of the correct recording).
