Here's one that is is free:
Put your track in your DAW. Duplicate twice (three tracks in total).
Convert the first to mono (route it to a mono bus for ex). Keep it at nominal level. Name it "Mid".
Convert the second in mono as well. Lower the fader to -∞. Invert the phase (polarity) and call it "Side-"
Keep the third in stereo. Lower the fader to -∞. Name it "Side+"
Link Side- and Side+ Faders or route them to a stereo group.
Play the track and slowly raise the Side- & + faders until you're happy with the image.
You can even high pass the sides to keep the lows mono if you want.
It's just a classic Mid Side matrix. There are other, more sophisticated stereo widening methods but it's always cool to know how to do it yourself imo.
+1 on this one, I think it's the safest stereo enhancement technique - and even for mastering applications.Here's one that is is free:
