This question already has an answer here:

Should i use Stereo expander (Wide field) on background music so vocal and music sound separate or is this really dumb question?

P.S - I dont know if this is important but voice is recorded in mono.While Background music is stereo.

  • What style of music are you producing? What's the intended audience, live music, cinema, home listening? – Simon Bosley Aug 11 '16 at 8:58
  • Home listening. I want to achive this kinda of mix. youtube.com/watch?v=AJ0Vqu4qsCg – iggy Aug 11 '16 at 17:29
  • @iggy It would be really useful if you listed all of the techniques you've used so far to separate the vocal and music. – Simon Bosley Aug 12 '16 at 7:49

It depends what you are trying to accomplish. Generally, you can accomplish the stereo expander's effect by using a bit of reverb. You'll want to also filter out any bass frequencies from that channel as well

Stereo Expanders are used all the time in lots of different contexts, but there are three things to watch out for when you do:

1: EQ. When the sound is stretched wide you can lose bass frequencies from the middle of the mix, or they can sound weird.

2: Wideners often use slight delays to the signal (panned hard left and right) which can cause phasing issues. Always check your mix in mono to make sure it still works.

3: Wideners can also use slight pitch shifting between left and right, which can result in a loss of musicality. Things like sound effects of explosions can be widened like crazy with no issues, but something like an orchestral symphony should be treated with some caution.

The basic answer is yes, use it, but look out for the above and tweak the settings to minimise any problems you can hear. I don't know if you're on Windows, but I have found the free SHEPPi Spatial Enhancer VST very useful for this kind of job.
