I created some field recordings using my iPhone so they were in mono. I
wanted to convert them to stereo so I pasted the left channel onto the right
channel a fraction of a second later to create a stereo effect. Someone
told me about phasing and how if the file is out of phase, you won't hear it
when you collapse the file to mono.
In my case, when I went to track and then to create mono file, I heard the
audio but it has this odd underlying artifact in it so I'm wondering if
there's a better way to convert a mono file to stereo so that, if it plays
on a mono speaker, I won't hear that strange underlying sound?
I tried a stereo plugin but it apparently made the file out of phase because
when I collapsed it back to mono, I didn't' hear anything.
I hope my question is at least sensible and that someone can give me some
good suggestions of best practices for converting a mono file to stereo.
Thanks for the help.
