摘要： The present invention provides an apparatus with sound source localization. Spatial information and original audios are synthesized by a mono signal analyzer/synthesizer of a multi-channel system to obtain a three-dimensional (3D) virtual reality sound effect. By extracting and synthesizing spatial parameters, only original audio objects and spatial location data are required to obtain an effect of multi-channel spatial audio. Thus, a multi-channel playback system is formed with a small bit stream in transference to obtain Doppler effect on simulating moving of audio objects in real life.

摘要： A down-mixing device is provided. 5.1-channel sounds are down-mixed into 4-channel sounds with high-quality multi-channel surrounding sound effect reappeared. A common-acoustic-pole and zero (CAPZ) model is used to rebuild frequency responses of original head-related transfer functions (HRTF). Direct sounds, reflection sounds and late reverberation in a spatial sound field are gathered. Thus, varieties of sounds become rich and 3-dimensional hearing experiences are enhanced with low cost for a 4-channel earphones system.

摘要： The present invention identifies boundaries of data packets within a serial data stream and transfers data belonging to these packets to an external device for processing or storage. Identification is accomplished at relatively high speed by parallel processing techniques using a state machine. Data may be transmitted through separate channels to a multiple channel link. This link selects one channel at a time for a predetermined period of time, and allows the data stream from the selected channel to be transmitted to the flag detector. Some of the bits in the digital data stream may be part of a flag. The flag detector generates a value corresponding to the number of bits which may correspond to a portion of a flag in the data that has entered the flag detector. Additional data from the digital data stream entering the flag detector may include the remaining bits of the flag. If so, then the detector indicates that a flag has been found. Based on the location of a flag, boundaries may be determined for data in a packet.
