According to the IASCA Rulebook:

The program material used in testing must be commercially available CD software (e.g. – store bought CDs), or MP3 players, iPods, tablets, flash drives, etc. CD-R’s and CD-RW’s are not allowed for use in competition. Any other reproduction format that is not listed is subject to the approval of the event Head Judge. Any commercially available
CD is acceptable at SPE and DPE events. For TKE and IdBL World Record Events, the Official IASCA IdBL “Max dB3” CD is the only acceptable CD for use. IASCA considers CD as its main media format for use in competition; alternate media (such as MP3 or iPod) may also be used in competition.
