Abstract: A method includes conducting a base portion of a game in which the base portion result may include a first trigger condition or a second trigger condition. Where the base portion result includes the first trigger condition, the method includes conducting a first bonus feature which may include activations of reels defining a first array of game symbol locations. Where the base portion result includes the second trigger condition, the method includes causing the display system to display a selection from among a number of different additional bonus feature options at least one of which comprises a reel-type bonus feature which includes activations of reels defining a second array of game symbol locations larger than the first array.

Abstract: A method of removing reverberation from audio signals is disclosed. The method comprises spectro-temporally analyzing the first audio signal and the second audio signal to derive an energy function of time for a plurality of frequency bands. The method further comprises determining a delay stability between the energy function of time for the first audio signal and the second audio signal in each band, determining a gain function in each band based on the delay stability, adjusting the energy of the first audio signal and the second audio signal using the gain function within each band, and resynthesizing audio signals from the energy in each band of the first audio signal and the second audio signal.
