  By analyzing the numerical representation of amplitude values in audio
signals and integrating the time component, a representation for audio signals
on quantum computers, FRQA, is proposed. The FRQA representation is a
normalized state that facilitates basic audio signal operations targeting these
parameters. The preparation and retrieval for FRQA are discussed and, based on
the FRQA state, we realize the circuits to accomplish basic audio signal
operations such as signal addition, signal inversion, signal delay, and signal
reversal. These operations can be employed as the major components to build
advanced operations for particular applications in the quantum computing
domain.
