At the audition everyone remained quiet. Why?

i sang "silent night" to audition for the university choir. now according to me and others my voice is good. I was accapted for the high school "Fiddler on the Roof" musical. I was in choirs since i was little. My friend who also auitioned for the university choir sang real soft and creaky, yet she got in. I auditioned and everyone remained quiet afterwards. People looked puzzled. I hav sang all my life I was horrified i didnt get in. They cudv said "oh honey some notes were false!" or something...but i just got this silence. I admit ive not sang for a year or two. sum peopl say i sing like Joan Baez. was i that bad??
