Information technology has multiplied for some decades. It has affected the way how the public interacts with their environment. Specifically, this technology helps us to work more efficiently than before. Nevertheless, some problems arise due to the exploitation of its weaknesses, like capturing confidential data. Some schemes have been introduced, such as embedding the secret in a multimedia file. However, the quality of the file after the embedding process may be different from its original form significantly. Moreover, there is a limitation on the secret size that can be hidden. In this research, we propose to improve the existing method by taking audio as the carrier. Specifically, we explore the mirroring technique after the audio samples are interpolated. It is to reflect the samples to the specified mirroring point, purposing to minimize the difference between before and after the payload is embedded. The more similar the stego to the cover file, the higher the quality; besides, the embedding space has been enlarged. The experimental result shows that this proposed method can increase the quality of the stego file by about 20 dB for various payload sizes.
