12.3.15. VBRfix
This function scans a VBR (Variable Bitrate) MP3 file and updates/creates the Xing
VBR header. The Xing header contains information about the VBR stream used to
calculate average bit rate, time information and to more accurately fwd/rew in the
stream. This function is especially useful when the playback of a file skips, fwd/rew does
not work correctly or the time display is incorrect. To use this plugin, open the Context
Menu (see section 4.1.2 (page 23)) upon a .mp3 file and select Open With. . . → vbrfix.
Note: VBRfix can only run when music is turned off (since it uses the same memory as
b
the player) and can take a while to complete if run on big files.
