7 Best Free Stereo to Mono Converter Software For Windows

Here is a list of best free stereo to mono converter software for Windows. Stereo or Stereophonic audio carries sound in two or more channels to create the impression that the sound is coming from different directions. Plus, each channel of stereo audio can carry completely different sound samples. On the other hand, Mono or Monophonic audio carries only one sound channel. Now, if you want to convert stereo to mono, this list of stereo to mono converter software will surely help you. These converters merge all the channels of stereo audio into one single channel to create mono audio. Through some of these converters, you can also perform mono to stereo conversion.

Most of these converters are dedicated audio editing software through which you can also modify input audio files before initiating the conversion. To edit the input audio, these software offers various Editing Tools (clip boundaries, duplicate, resample, trim, swap channels, etc.) and Effects (tones, silence, noise, etc.). In some software, you can also find filters to filter out certain frequencies from the input audio. Besides editing tools, you also get the visual representation of input audio files in the form of waveforms in most converters. However, the main advantage of these converters is their ability to support many audio formats like WAV, MP3, AAC, OGG, FLAC, etc.

The process of conversion is quite straightforward in all software. Still, to help you out, I have included the conversion steps in the description of each software. Go through the list to know more about these converters.
