A method of producing trigger based upon an autocorrelation measurement ... 06/01/06 - 20060116871 - Apparatus, method, and medium for processing audio signal using correlation between bands Apparatus, method, and medium for processing an audio signal using a correlation between bands are provided. The apparatus includes an encoding unit encoding an input audio signal and a decoding unit decoding the encoded input audio signal. The encoding unit includes a correlation analyzer searching a most subband having a ... 03/09/06 - 20060053003 - Acoustic interval detection method and device There is provided a harmonic structure acoustic signal detection device not depending on the level fluctuation of the input signal, having an excellent real time property and noise resistance. The device includes: an FFT unit (200) which performs FFT on an input signal and calculates a power spectrum component for ... 11/24/05 - 20050261895 - Methods and devices for correlating audio sample comparisons and network performance statistics Methods and devices for evaluating audio quality in a network are described. First and second audio samples are compared. The first audio sample includes a reference signal that is transmitted through a path on the network. The second audio sample includes the reference signal after it has traveled the path ... 08/18/05 - 20050182620 - Voice activity detector A system and method is provided for determining whether a data frame of a coded speech signal corresponds to voice or to noise. In one embodiment, a voice activity detector determines a cross-correlation of data. If the cross-correlation is lower than a predetermined cross-correlation value, then the data frame corresponds ... 06/30/05 - 20050143982 - Method and system for accelerating power complementary cumulative distribution function measurements Data values representing the (I2+Q2) values are converted to floating-point representations and a histogram of the floating-point numbers is generated. The count for each histogram bin in the histogram is stored in a memory. Each floating-point number acts as an address for a corresponding histogram bin in the memory. The ... ### FreshPatents.com Support |
