hi audacity team just wondering how i can make a voiceover in audacity using an 80’s synthesizer
as heard in here [url][/url]

Mixing voice with music is described in the manual here:

Not with music lol what I’m asking is is there a plug-in for synthesizer as heard in the link
I gave you, when they say synth and son
That’s a synthesizer behind that voice or so I would of thought!

Audacity is an audio editor. It sounds like you are looking for a “digital audio workstation” (DAW). Take a look at “Reaper” for a low cost DAW.
