This paper presents new two-channel test stimuli for the evaluation of systems where traditional monophonic test signals are not suitable. The test stimuli consist of a series of exponential sine sweep signals with varying inter-channel level difference and inter-channel phase difference. As a case study the test signals have been used to evaluate a selection of 2-n channel upmixers within a consumer audio-visual receiver. Results from using the new stimuli have been shown to provide useful insight for the improvement and development of future upmixers.
