AB  - This article presents a subjective evaluation of a proprietary sub-band ADPCM (Adaptive Differential Pulse Code Modulation) codec for digital wireless transmission. The evaluation is carried out with 40 expert listeners and is divided into several experimental stages: First, the audibility threshold for codec artifacts is determined for each frequency sub-band, separately. In the next stage, different configurations are ranked on a scale of subjective sound quality ratings, with the resolutions varied across all bands. Finally, selected configurations corresponding to different quality ratings are compared to signals of analog wireless transmission in a multidimensional test. This test reveals the characteristic artifacts of each transmission method. Overall, digital transmission can achieve a better sound quality than analog transmission.
