It's not as easy as downloading backing tracks and expecting all the levels to be correct. All tracks have different EQ's that require balancing so that the bass isn't too boomy or the high-end EQ isn't too piercing.
Volumes then need levelling out so that they playback just like your favourite songs on a standard CD. You never have to reach for the volume control between songs on a CD, right??? This is because they have been produced to a specific broadcast standard. The same is true when it comes to using backing tracks live on stage. The same can be said for Voiceovers, Podcasts, YouTube audio etc, etc.
If you're looking for that professional balanced sound and levels on ALL your audio, then we can help.
(We produce the vast majority of our backing tracks from stems that we already have on file or can source from 3rd party studio's. This enables us to produce them for you at such a low cost. However, if the stem files aren't readily available, your track would have to be recorded from scratch which can cost £300 or more.)
