First of all, it seems that your vocal track is untreated: compressor, normalization... judging by the waveform.
Treating vocal tracks is important so that the voice stands out well over a music track or a bed.
And this processing is done before integrating your vocal track with Audacity for example. And not with RadioBOSS which can only adjust the volume.
Regarding your
vocal track, here’s what I suggest. Right-click and open the
Track Tool:
• Define the start mix point => Start. This indicates where the track begins.
• Define the mix point => Mix. This indicates when the next element should chain onto this track.
• Define the end mix point => End. This point is always after the “Mix” point and indicates the playback end of this track.
This is the minimum I do. This way, we provide temporal indications that will be used in other programs.
Adjust the volume level of this vocal track as well, still in the Track Tool => Playback Level (at the bottom of the waveform's start).
The level of your vocal track seems very low to me. But it all depends on the sound level of your music track...
Next, select your
music track, which will have your vocal track as an intro:
• Open Track Tool (right-click).
• On the waveform, click where you want your vocal track to begin.
• Click “Set” for “Voice Ins.” You’ll see timing appear (refer to my first screenshot). Adjust this value according to your needs.
• Click on the three small dots “...” on this same “Voice Ins” line.
• A “Voice Insert” window will open.
• Select your vocal track and apply the settings you wish.
That’s how I proceed. But this is only my perspective. And it works. If it doesn’t work, I suggest leaving another comment.
Support will be much more competent and will respond to you early next week.
