Voice Trap is an audio tool that was designed to help eliminate and isolate vocals within a track.
Generally, vocals are removed from a track by subtracting the left audio channel from the right one but that generally leaves you with mono output and various other quality mishaps. Voice Trap uses two DSP algorithms ( FFT-based center channel suppression and isolation, along with cepstral liftering) which enable you to keep the stereo output and leave the bass frequencies as they were.
It’s a lightweight plugin that fits well in your VST host and allows you to either remove the vocals or isolate them. So, Voice Trap seems to have the best interest at heart for both karaoke enthusiasts and music producers that are looking to take a fresh voice and combine it with a new beat.
Doing these things sounds great in theory but in practice things are a bit different. The plugin has no control over the structure of the track and it can not literally disassemble and separate the vocals from the negative. What it does, is it analyzes the signal using complex mathematical algorithms and let’s you adjust a series of parameters until you obtain the effect you need.
Voice Trap offers you the use of bass cutoff, center width, profile phase, track low, range, track node and other parameters which you can freely use until you either isolate or remove the vocals.
All in all, using Voice Trap is mostly a trial and error process until you obtain what you need. Math may be an exact science but in this case it won’t accurately please your ears on the first go.
In closing, the math behind Voice Trap is complex, but the plugin itself is very easy to use and if you have enough patience with it it can certainly get yoa to where you need.
