audio files won't play

[KristyLDavis]

Hello,

I can't get the attached audio files to play in directRT (instead there is an 'error' ding). I believe they are saved in 16 bit format (as recommended in other posts on the forum). Are there other parameters that audio files must meet in order to be recognized?

I have attached the input file and samples of the audio files that I am having trouble with.

thank you!
