How to calculate minutes for audio tracks

[Collins]

I'm converting some of my daughter's mp3 music collection to wav
format and burning cd's for her.  I'm using the old mp32wav script
(mpg123 and sox) to do the conversions and cdrecord to burn the cd's.

One of the advantages of the accursed Windows programs (CD Creator,
etc.) is that they calculate the number of minutes for a track,
whereas I have to guess at how many trakcs will fit of a cd.

Does anyone know how to do this in Linux fashion?

TIA
