  1. Launch EP

  2. Drag Mp3 files to Engine Prime from desktop or a folder

Same track converted to AIFF, ALAC, WAV, AAC shows true track length

  • Actual Result: (ex: It does Y…)

MP3s shows a short track length in secs

  • Reproducibility: (ex: Happens 1 out of 10 times.)

10 out of 10

Were the mp3 variable bit rate?

Hi @mufasa,

Thank you for the report.

Does this happen for all tracks dragged from a folder into Engine Prime?

my normal EP library is via the Serato Update. I didn’t notice the abnormal length in my main library. But then I have probably analyzed my entire library at some point.

I was trying to troubleshoot something else with some test tracks in a folder on my desktop.

Made various copies of a song in different formats and I noticed that the MP3s dis not have the correct time length

But I will download a few tracks straight to my desktop now and test again.

Got it. The image above is that showing Serato view?

No. Collection View in the images above.

13 test tracks - just downloaded from record pool

Drag and drop from Desktop


3 (three) mp3 came up with the short length, Library sorted by track length

Same tracks again with tags stripped

Anyways it doesn’t affect performance!
