I shot an interview with a Canon 6D MII using an external microphone. When exporting the mp4 videos (which exports audio all in one) the audio is pretty 'tinny' and bad, which is obvisouly a camera/ mic problem, but I am confused about different audio forms. For the same project, I recorded audio as a WAV on a cellphone and it shows the audio as one single waveform and this audio is great. The audio from my Canon shows two identical wave forms in one track. I am wondering if this difference, or the audio coming from an Mp4 is the issue. I've tried googling it but I can't seem to get onto the right page regarding it or I can't find the corret terminology. I am wondering if this 'waveform' type is causing the echoey sound, or is that just a stereo track and the other is a mono?
I realised soon after posting this that it was just mono and stereo sound, but is it a problem editing mono and stereo sound together? They are from different sources so they sound different, but I thought that maybe making stereo mono will help?
