IMBE (Improved Multi-Band Excitation) is a technique for compression and encoding of voice signal. In a digital communication system, a tone is often coded into IMBE vectors at the source and the IMBE vectors are decoded at the destination. This coding and decoding causes significant distortion in the tone.
