Incomplete Variable Bitrate MP3's

voxson · 20th April 2002, 14:11

I know that variable bitrate MP3s cannot have their length estimated. You can't calculate their length by dividing size/bitrate since the bitrate changes all the time. This is why encoders add a tag in the beginning of the file mentioning the song length. But what troubles me is with some incomplete MP3's I have. They are reported as having the ful length (since this is what the tag suggests) but they are much smaller. What can I do so WinAmp will display correct song length and progress?

Please download MP3Utility or Encspot, and use them to analyze those VBR MP3s.

It could be due to FhG VBRI headers causing the mp3 decoder problems.

1) Problem reading time/bitrate of FhG VBRI MP3 headers, reported here

Egg's comments: [revised: 01/09/01]
Problem caused by in_mp3.dll's inability to correctly read VBRI frame headers in MP3's encoded with rippers using the FhG encoder (MMJB, FastEnc, etc) Files play ok, but time display & bitrate readings are messed up.

...and don't forget to try Peter's vbrfix too.
You can also checkmark "show average bitrate for vbr" in MPEG Audio Decoder config (c/o Prefs -> Plugins -> Output -> in_mp3.dll -> config -> decoder tab), though this is probably irrelevant to this particular case?
