notch filter software - Shure DFR22
Shure DFR22 Two Channel Feedback Reduction Tool with 16 Automaticaly Adaptive Notch Filters
Shure DFR22 Two Channel Feedback Reduction Tool with 16 Automaticaly Adaptive Notch Filters
Shure’s DFR has quickly become the industry standard for effective feedback reduction. The DFR22 builds on that reputation to provide an affordable full-featured 2x2 audio processor with Shure’s drag-and-drop software. It’s much more than feedback reduction. For many jobs, it’s the only audio processor you’ll need. Featuring enhancements to Shure’s patented Adaptive Notch Filter Algorithm, the DFR22 includes single-channel and stereo processing blocks with up to 16 precision notch filters that automatically seek out and reduce feedback. With widths between 1/10 and 1/70 of an octave, these adaptive filters affect only the problem frequencies, maximizing system stability and sound integrity. In addition, Auto Clear mode removes dynamic filters and restores the DFR to your ideally-tuned configuration after a specified amount of time. The DFR22 has all of the DSP processing you need to ensure the highest quality audio. Processing blocks in the DFR22 can be applied in any order, to any input or output. You can also link processors for more efficient global control. Copy and paste processing blocks to any input or output to duplicate processors across multiple channels. With the DFR22, you can design the entire system, save it to disk, and load it at the job site for easy setup.

Performance analysis of filtering software using Signal Detection Theory [An article from: Decision Support Systems]

Description:
Software filters are increasingly being touted as a solution to restrict access to inappropriate information in a variety of settings. Families want to protect young children from pornographic sites, corporations are searching for ways to minimize trivial use of the Internet by their employees, and non-profit organizations look to control information access to reflect the value system of their communities. Despite the exponential increase in software filter usage, its effectiveness is not clear. In addition, critics of the approach argue that mandated use of filtering software on public computers like libraries may result in denial of vital information to poorer sections of the society who do not have independent access to the Internet, thereby curbing intellectual freedom and creating inequity in access to information. The purpose of this study is to analytically evaluate the performance of software filters using the Signal Detection Theory (SDT) framework. Two types of software filters are modeled and analyzed-simple software filter (single method) and a sequence of software filters (multiple methods). Analysis shows the limited capability of both types of filters, with the multiple-method filter outperforming the simple filter. Results of this study caution proponent of filter-based solution to be realistic with expectations of the benefits of filtering based solutions. Implications of the findings for proper use and design of software filters are discussed.
