Computer‐steered microphone arrays provide an attractive sound‐transducing means for interactive communication by sizable groups of talkers. But the spatial acuity of arrays typically varies with frequency, exhibiting diminishing beamwidth as frequency increases. Frequency‐weighting the array is one means to mitigate the variation and to achieve more uniform beamwidth over the useful frequency range. Acoustic low‐pass filtering, accomplished in the array design, provides effective and economical modification of beamwidth.
