Device Closed loop # of biquads DRC 3D/bass 1-Ku price boost TAS5707 No 14 Single-band No $2.
D-Pro Windows Software makes speaker correction, setting up crossovers, and equalization easy by allowing the user to import multiple speaker response measurement files that are plotted on a graph and visually equalized by manipulating selected biquad filters using Visual-Handles that can be dragged with a mouse.
Continuous-time Biquad and Ladder Filters are very complex functions that have been burdensome and involved for analog designers.
The new devices enable designers to implement enhanced audio features:3D to increase the spatial sweet spot of compact consumer electronics products; dynamic range compression to automatically adjust the audio to the desired loudness range while protecting the speaker and preventing clipping and distortion; and multiple biquads to equalize the speaker or microphone.
It can be configured easily via digital control to operate in one of several different output modes, and offers a full range of processing and equalization options, including up to 4 programmable 28-bit biquads per channel, and bass and treble tone control.
