Abstract: This invention discloses a method of frequency band group partition for wideband audio codec. It can determine the initial frequency band group partition within the whole effective range of frequency bands. It further subdivides frequency band groups based on the initial partition. Instead of the iteration-based algorithm, this invention applies the 1-from-2 and 1-from-3 criterions to accomplish the fast partition with at most 3 subdivisions. This invention implements the fast partition for frequency band group without the loss of the coding efficiency. By applying this fast partition method, one can greatly reduce the computational complexity and significantly improve the coding performance.

The EDI inner module preferably has one concentrate center pipe as the electrode in the center axis and at least one layer of anion/cation exchange membranes and a support frame in concentrate/dilute chambers wound around the center pipe. The electrode plate is inside the encircled cylindrical shell (isolating vessel). It is connected to an electrical contact plate located in the shell. Either the anode or cathode can be set in the center pipe, and the other electrode can be set in the vessel or shell lining. The electrical contact plate also contacts an electrical contact reed located on the vessel cover when the cover is connected to the shell. The electrical contact plate provides a reliable conductive bridge between the contact reed and the electrode plate and thus passes DC from the contact reed to the electrode plate.
