I recorded a live event, the sound came from the audio guy through a balanced XLR to 3.5mm cable.
When watching the recording I get extremely quiet and distorted audio.
I was able to figure out that if I silence either right or left side the audio sounds normal.
I was also able to figure out the issue only happens on devices with only one speaker. Most probably this is related to silencing one side.
Something is telling me this is related to that fact I used a balanced cable, something to the sense the audio is canceled out by the two opposite signals, and that's why it works when I disable the signal from one side.
What is interesting though, I recorded multiple events with the same cable with other audio people, I only have the issue with one audio guy's output.
I'm trying to figure out what actually happened here?
What do I need to tell the audio guy in the future to prevent it from happening again?
And last how can I fix the current recording it should play on any device correctly?
