6 Best Free Mono to Stereo Converter Software For Windows

Here is a list of best free mono to stereo converter software for Windows. Mono or Monophonic is a single channel audio that produces the exact same audio in both left and right speakers. On the other hand, Stereo or Stereophonic audio is multi-channel audio that can carry the same or different audio signals on its multiple channels. The advantage of stereo audio is its ability to produce surround sound in which you can clearly distinguish the sound and position of different musical instruments. So, in order to convert mono audio to stereo, you can use these free mono to stereo converters.

In order to convert mono to stereo, these software copies the same mono audio in two or more individual channels. You can later edit individual channels to produce real stereo sound. The process of conversion is pretty simple in all of these converters. Still, I have included the complete conversion steps in the description of each software that you can check out.

Most of these converters are primarily audio editing software, thus you can also edit mono audio using them. To edit input audio files, these software offer Editing Tools (copy, mix paste, delete selection, clip boundaries, etc.), Effects (change pitch, change speed, echo, and more), and Filters (HPF, LPF, BPF, and others). In addition to these tools, you get a separate editing section that shows the waveforms of input audio files. You can also find some useful additional tools in these converters, such as Audio Player, Plugin Support, Statistics Viewer, etc. Go through the list to know more about these converters.
