when I am recording a set the audio stops randomly.. the last two sets i have recorded the audio stopped long before the set was over.. the first time the set was 2 hours audio stopped around 45min... this last time.. while recording Cedric Gervais set it stopped at 15min out of the hour set... why is this? It shows the audio input the entire time... never stops until i tell it to by pushing stop recording.. the project file says its the full length... however the separate wav file never is the full set?
