Rotation-dependent left-ear CS of the acoustic crosstalk cancellation (CTC) system, implemented as 4-CTC (β = 0.05). The CS was calculated (a) without and (b) with additional room reflections in spatial playback transfer functions, that is, head-related transfer functions (HRTFs, theoretical CS) or binaural room impulse responses (BRIRs, practical CS), both measured in the example listening environment. (a) Calculated CS after applying CTC filters on playback HRTFs. (b) Calculated CS after applying CTC filters on playback BRIRs. For better readability, spectral smoothing using filters with constant relative bandwidth of one-third octave was applied.

Note. CS = channel separation.
