This article covers 5 websites to convert Mono to Stereo online for free. Do you ever stumble upon a song that only plays in one of your earphones? That’s because the song has mono audio or your earphones are defective. Anyway, Mono audio has a single audio channel whereas Stereo audio has two or more independent audio channels. If you are listening to a mono track with a multi-speaker setup or earphones, it only plays in one speaker or earbud.
To play a mono track on multiple speakers or a pair of earphones, you first have to add another audio channel to it. In other words, you have to convert mono to Stereo. For that, you can copy the mono channel to make it stereo. This won’t add any special 3D audio effect to the sound but the song would play on all the connected speakers.
Here I covered 5 free websites where you can convert mono to stereo online. The conversion process is almost identical to all the websites. You can upload a mono track to any of these websites and change the audio channel to stereo to add at least one more audio channel to the track. Some of these websites also give you an option to add up to 5 audio channels to make 5.1 stereo. With that said, let’s check out these websites in detail.
