Tertiary Audition

[wohltemperierte]

I'm just wondering if anyone, preferably someone who works in the faculty of Arts, department of Music knows how long of a period of the recorded audition tape is kept for an audition for Tertiary at Masters level?  I emailed the person who auditioned me if I can have a copy of my audition recording one month after my audition, but the person replied to me one month later stating that my audition has been erased as the audition process is over! 0.0 Is this the regulation of the department?
