Audio signal time-scale modification method using variable length synthesis and reduced cross-correlation computations

Disclosed is an audio signal time-scale modification which utilizes variable length synthesis for the improvement of output audio quality and reduced cross-correlation computations for the reduction of computation loads to a processor. An analysis window consisting of N+Kmax audio samples is selected from an input audio samples and is shifted by the predetermined interval along output audio samples to find optimal shift Km, which ensures best cross-correlation between Nov audio samples of the analysis window and last Nov audio samples of the output audio samples and a particular value of Nm at which a coefficient of correlation between them is larger than a reference value or is the maximum one among a plurality of coefficients of correlation calculated with varying the value of Nov. The audio samples involved in the calculation of cross-correlation are down-selected by the predetermined ratio from Nov audio samples of the analysis window and last Nov audio samples of the output audio samples, respectively. The analysis window may also be shifted by the plurality of audio samples per one shift. The audio samples ranged region (Km+Nov−Nm)th sample in the analysis window is determined as an add frame. The existing last Nm audio samples of the output audio samples are replaced with new Nm audio samples obtained by weighting and adding the overlapped parts, i.e., the first Nm audio samples of the add frame and the last Nm audio samples of the output audio samples, while remaining part of the add frame is simply appended to the tail of the new Nm audio samples in the output audio samples.

Time-scale modification method for digital audio signal and digital audio/video signal, and variable speed reproducing method of digital television signal by using the same method

Problem: A method capable of ensuring a synchronization between an audio signal and a video signal both of which are modified in time-scale is needed. Solution: When analysis shift Sa=Ss/α, where Ss is synthesis shift and α is a designated time-scale (variable speed ratio), has a decimal value, two natural numbers which are nearest to the decimal value are selected as a modified analysis shift Sa′ and a compensated analysis shift Sa″, respectively. In time-scale modification of source audio samples to vary playback speed by dividing them into overlapped successive analysis windows, the modified analysis shift Sa′ and the compensated analysis shift Sa″ are alternately applied whenever a predetermined condition is met. The time difference between an estimated playback time and a real playback time of the time-scale modified audio signal is accumulated. The case that the predetermined condition is met is a case than an accumulated time difference goes beyond an upper threshold or a lower threshold of an allowed error range. In a processing of varying the playback speed of an AV signal, if a real variable speed ratio of a playback-speed-varied video signal is given as a target variable speed ratio of an audio signal to vary the playback speed of the audio signal, a synchronization between the video signal and the audio signal can be obtained. By applying this technology to the digital TV or TV phone, consecutive watch of the broadcasting signal for a phone-break time is possible. Catch-up for the currently received broadcasting signal is also possible through a high speed playback mode after a low speed playback mode initiated from a time of the past or the present.
