F-REX can analyze the sound that’s being played in real-time into the three parameters 'Volume', 'Frequency', and 'Panning' and graphically visualize them.
You can control independently the inside and the outside area of the specific part focused by panning and frequency. You can apply effects (compressor and reverb) to the sound and adjust volume and panning intuitively.
These functions make you create 'minus-one songs'. F-REX can find a specific sound in the song, for example, the vocal part, and minimize its volume. 'Noise canceling' can be done as well. Also adjusting the volume to specific instruments makes the sound more audible and learn a song easier. F-REX can be used for various purposes and you can produce unique remixes sound.
