In this study, quantum representation of multichannel adio (QRMA) that can be used in many fields in future is proposed. The QRMA uses three entangled qubit sequences where time, channel, negative and positive amplitude values can be stored. The three-qubit sequences are in basis state: |0 and |1. The preparation of the QRMA starting from the initial state |0 is presented. In addition, multichannel audio is obtained from the QRMA quantum state. Several operations such as signal merging, signal addition, signal inversion, signal reversal, channel merging and channel reversal are studied on the QRMA. The simulations and the analyses show that the QRMA has more advantages than the other models in the literature.
