Unfortunately, most all conventional side-chaining plug-ins will not work in Vegas.The only side-chain comp I can recall off-hand that works with Vegas Pro is from 'db Audioware'. It worked decent but I prefer to 'draw' a manual volume envelope... though it takes much more time. FWIW, I been asking for side-chaining options since the first Sonic Foundry release of Vegas, which was an audio-only DAW.
+1 Vegasaur Voice Over. It gives you lots of precise control over the volume envelope creation. Huge time-saver.
Yes i tried so far. But cant make it happen so far that its usable. Need to find this week a guide which explains each option and what it exactly does. So far it sometimes just does the opposite and lowers the volume in parts were there is no word at all.
the problem is, if you have many cut first of all the voice over tool in vegasaur takes so much time and second, it has clearly a hard time to figure stuff out and does not the best job so.
however, i think i found the solution. if one has many cuts in the voice over track, because its connected to a video and you edited a lot of it, first just export it as an wave audio and import it back, mute every other track now and apply the vegasaur voice over and it should be totally fine and way way quicker.
