Voice Trap is an advanced audio program for Windows designed to help you eliminate and isolate vocals within a track. Generally, these parts are removed by subtracting the left audio channel from the right one, which leaves you with mono output. However, the utility allows you to keep the stereo and even save the bass frequencies, thanks to the use of two DSP algorithms.

Review

Voice Trap comes in the form of a plugin that suits a wide range VST hosts. It gives you the ability to either remove the vocals or simply isolate them. Unfortunately, the tool has no control over the structure of the track and it cannot disassemble and separate the original sound from the negative. What it does is it analyzes the signal using mathematical algorithms and lets you configure various parameters until you achieve the effect you want.

Configuration

The application offers you the use of bass cutoff, profile phase, range, center width and other parameters. With the help of these, you can customize the vocals. All in all, the process consists of trial and error. The math behind the main features is quite complex, but the plugin itself is very easy to use. If you want to repitch your voice, you may use another product called Antares AutoTune.
