Audio corresponding to the moving picture of a virtual reality (VR) camera can be recorded using a VR microphone. The resulting A or B-format channels are decoded with respect to the look-direction for generating binaural or multichannel audio following the visual scene. Existing post-production tools are limited to only linear matrixing and filtering of the recorded channels when only the signal of a VR microphone is available. A time-frequency adaptive method is presented: providing native B-format manipulations, such as equalization, which can be applied to sound arriving from a specific direction with a high spatial resolution, yielding a backwards compatible modified B-format signal. Both linear and adaptive approaches are compared to the ideal case of truly equalized sources.
