The latest version of XLD has added a option to the Lame MP3 encoder "Append a TLEN (track Length) tag" it is turned on by default after some searching i really can't find out what it's for.

Wondering if someone could provide some info on it.

Thanks:)

It appears to be required for Windows/WMP and probably other applications to report the correct track length. Refs from a forum Google search for "MP3 TLEN":

Also: According to the ID3v2.4.0 frame reference, and logically enough, it enables seektables and thus better seeking in VBR files:
QUOTE
Audio seek point index

Audio files with variable bit rates are intrinsically difficult to
deal with in the case of seeking within the file. The ASPI frame
makes seeking easier by providing a list a seek points within the
audio file. The seek points are a fractional offset within the audio
data, providing a starting point from which to find an appropriate
point to start decoding. The presence of an ASPI frame requires the
existence of a TLEN frame, indicating the duration of the file in
milliseconds.

Thanks.

So it seems it will do no harm leaving it on.
