7 Best Free Stereo Widener VST/AU plugins for Music Producers

The importance of wide stereo sound is an accepted truth for the music producers and artists. This is required both while mixing and while recording. Music production will not be that vibrant without the wide stereo sound.

Bluemelein or Mid side technique help to get that effect while recording the music, but when you need to add the effect on the pre-recorded music or song, then it becomes a problem. However, in the modern era of technology, the software can sort any issue. This wide stereo effect also can be achieved by using a software plug-in while playing the track in DAW.

To solve this problem, quite a few free VST and AU plug-in have been developed, and we will now probe into them to know which plug-ins are best for this purpose.

It has a fully-featured version, but here we will be talking about the simpler Ozone imager counterpart. This technique is used to narrow or widen the image of your audio track so you can precisely modify that.

The brand Ozone is famous for their imaging technique, so this plug-in also helps to provide visual feedback of the audio playing in DAW. This is the best option for you to set the parameters while working on the modification of the track. The vectorscope and correlation meter is also present in this plug-in so you can precisely soundstage while mastering the width of the track.

  • Voxengo Stereo Touch

Stereo Touch works with mid or side coding and it can transform the most basic mono sources to stereophonic sounds. When you are working with mono sources with lesser or no impact, like sharp transient or loud musical instruments, it can be spiced up by widening acoustic or synthesizer, electrical guitar and vocals. This plug-in can create magic with the spaces. The expansive surround produced by this plug-in is just the right thing to avoid double tracking.

You can easily get that effect by using this plug-in and will not have to spend time and energy on that. It can work on multi-channel input signals and treats each signal as a mono signal independently. The output will be a single stereo signal after the stereos are streamed together.

  • A1StereoControl by A1Audio

The name of this plug-in says it all. The stereo image can be precisely controlled with this. Aided only with a single knob, you can utilize this plug-in to expand or limit the track to the utmost degree. While stereoizing bass sounds, you can surpass the common issues, with the help of “safe bass” algorithm. This helps to centralize all the low frequencies below the threshold where the users will be unable to define them.

Thus bass and other low-end sounds are kept at the centre of the stereo spread, and no phasing issue comes up. There is no particular side or mid control in the imaging, still, this plug-in keeps the low end away the low end sounds so those did not collapse on the mono.

  • MAutopan by MeldaProduction

This, unlike the previous ones, is not a dedicated stereo imager. You can rather call it a panning plug-in. but still, it is quite capable of stereo imaging.

When you need to handle more than mono and stereo sources, check MAutopan. This plug-in can processes up to eight channels, along with the surround audio. Thus it is not only a studio device for track modification but also a great game tool and can be used in film audio production.
