“I have an audio file that only plays sound from the left channel, which means I’m hearing nothing from my right speaker. Is there any way to fix this?”
If you’re only getting audio from the left channel of an audio file, that means whoever saved the file stored blank information on the right channel. You can fix the file so that it plays across both the left and right channels, but you won’t be able to create a true stereo experience isolating portions of the audio in either the left or right channel the way a commercial audio CD might. To fix the file, you’ll need download some audio conversion software.
There are several audio converter applications capable of fixing your audio file. The one I find easiest to use for this purpose is Switch, because it exposes the necessary conversion features in a very simple way (and it’s also free for most uses).
Before you begin you need to download Switch Audio Converter and install it. It works with both Windows and Mac, making it a fairly universal solution. Once you have Switch Audio Converter installed, launch the application.
Add your file to Switch then choose the encoder settings.
