How to Change from Mono to Stereo?

Before converting mono to stereo, an important thing to note is that we cannot make a true stereo effect out of the mono audio. What we created from the mono audio is a dual-mono, or pseudo-stereo, meaning that the sound coming out from the two audio channels is the same. That said, changing mono to stereo is still useful because some uploading platforms do not accept mono audio. And if you are using a mono device, the mono audio will only come out in the left earbud, which is uncomfortable. To avoid such annoyances, it is necessary to make mono audio stereo.

In the following article, we will show you how to convert mono to stereo in three different methods. Read on!
