The MarkIII microphone array: the modified version realized at ITC-irst
Claudio Bertotti · 2004
In the next section, each problem is addressed in more detail. Note that the first three points are reported (although they could be considered as trivial) because some partners in CHIL [2] could find useful verifying their entity in the recordings so far done at their site. On the other hand, problems 4-6 refer to very crucial aspects, which may cause misleading results in source localization, beamforming, or any other multi-channel processing based on the assumption of electrical noise independence across channels. In some cases, the tools used to evidence the given problems are not described in detail, assuming the readers are familiar with the related concepts (as, for instance, cross-power spectrum phase analysis). Some of these tools will be made available soon in the CHIL web site. References are anyway reported for a further investigation and we are always available for further clarification.
