The PCAP II Plus is applicable to a broad spectrum of voice and similar audio signals. It attacks a
wide variety of noises in forensic applications. Body microphone, cassette, microcassette, telephone,
broadcast, and hi-fi audio signals can all be processed efficiently, since the PCAP II can be set to
operate at bandwidths of 3.2, 5.4, 6.5, 8.0, 11, and 16 kHz.
The PCAP II is designed to replace an entire rack of audio processing equipment. With monophonic
signals, as many as 12 sequential stages of digital processing can be performed simultaneously. With
stereo signals, nine sequential stages of stereo processing are available. A broad selection of filter
types/options is available in each of the processing stages.
An easy-to-use Microsoft Windows-based Master Control program allows intuitive control of the
entire process, including bandwidth selection, mono/stereo configuration, and number of digital
processing stages. Individual process controls and filter modes for each digital stage are easily
specified. Input and output level bargraphs are displayed, and the signal frequency spectrum at any
point in the process can be displayed utilizing the built-in spectrum analyzer. Also, the built-in
coefficient display allows the filter solutions for all adaptive filters to be viewed with ease.
