This really should get a better mp3p/4035223/
EDIT: better mp3:
Also should be Disqualified cause the audio isnt really 128kbps
Top left: source ogg
Top right: 128 kbps mp3 from source ogg
Bottom left: beatmap audio
Bottom right: youtube video audio Note the names are virtually the same.
I can almost guarantee that the source (best quality I could find was the ogg submitted to the contest) was not used. Instead the 96 kbps mp4 audio stream from the video was used and encoded to 128 kbps resulting in the cutoff at 15kHz (which is expected of an mp3 at 96kHz).
It would be good to use a spectrum analyzer during the qualification process to confirm that the cutoff is above 16kHz (128 kbps mp3). The upper limit would be 19kHz for 192 kbps, but that's not important for obvious reasons. This is supposed to come out during modding, but clearly this is getting missed as it is a tedious process such as checking for metadata consistency prior to automation via AIMod and AIBat. It could be automated, but I sincerely doubt that anyone has the time or energy to figure something like this out. I wasn't able to find a simple program to do this automatically without visual inspection.
The song's audio file must be of reasonable quality. Try and source mp3 files yourself; ripping them from a streaming video site often results in low quality audio with high file sizes. The bitrate of a beatmap's audio file must be no lower than 128kbps and no higher than 192kbps. If you are having trouble acquiring an appropriate audio file, contact one of the more audio-savvy BN; they will be more than happy to help find an mp3 for you.
I got the mp3 from the sdvx kac album that was just recently released. I can send you the original mp3 so you can encode it or something
