This article covers 5 websites where you can convert Stereo to Mono online for free. Stereo sound has two or more independent audio channels and thus needs two or speakers. Whereas Mono sound only contains a single audio channel and thus only needs a single speaker.
With multiple audio channels, Stereo is used to create an illusion of a multi-directional audible perspective. For example, many songs these days use the stereo (multiple audio channels) where you listen to each channel separately in each earbud/speaker. If you play a song that has multiple audio channels on a single speaker, it won’t play the other channels and the respective audio would be missing. So, if you want to play a Stereo sound on a single speaker, first you have to convert it to mono. Doing this will combine all the audio channels of Stereo into a single audio channel for mono and hence nothing would be missing.
Here I covered 5 free websites where you can convert Stereo to Mono. You can add your Stereo audio files to these websites and convert them to mono by selecting the single audio channel. Some of these websites convert one file at a time whereas some lets you convert multiple files simultaneously. Apart from uploading files from your computer, you can also fetch audio files via URLs or from popular cloud storage platforms. With that said, let’s check them out one by one.
