Thanks Mike – All track files were intact (pulled into pro tools no problem) but I’d need to listen to 90 minutes of repeat event to see if anything got dropped. Dropped audio of about 2 seconds has happened before (noticed by the presenter one one occasion), but I’d need to listen in its entirety to know if anything was dropped from the other night. Not gonna do that because it’s just an archive copy of no consequence.
I had this dropped-audio problem on a QSC touchmix a few years ago – tried many different USB drives – QSC support was no help identifying the source. The WAVs aren’t corrupted – but 1-2 seconds of audio would just drop out – not leaving a silent ‘gap’ in the recording – just lost audio. The future audio just butts up against the previous audio – like in pro tools if you used shuffle mode, removed 2 seconds from a track, the “right side audio” from the splice would automatically slide left and butt up against the “left side audio” from the splice leaving no gap. Just the noticeable loss of audio during those 1-2 seconds.
Anyway – thank you for the explanation. Very much appreciated.
