You haven't exited MixEmergency before stopping the recording have you? This can cause a loss of audio. How long is the video for the performance? And can you try this: 1) Open the Terminal application (in the Utilities folder within your Applications folder) 2) Type this into the Terminal window: afinfo 3) Drag and drop the recorded wav file from the performance onto the Terminal window 4) Push enter/return 5) Copy and paste the output back into this discussion You should see something like this: nick-macbook-pro:~ nick$ afinfo /Users/nick/Movies/MixEmergencyRecording/Recording.MixEmergencyPerformance.wav File: /Users/nick/Movies/MixEmergencyRecording/Recording.MixEmergencyPerformance.wav File type ID: WAVE Data format: 2 ch, 44100 Hz, 'lpcm' (0x0000000C) 16-bit little-endian signed integer no channel layout. estimated duration: 13.340 sec audio bytes: 2353152 audio packets: 588288 bit rate: 1411200 bits per second packet size upper bound: 4 audio data file offset: 4096 optimized ----
