摘要： Disclosed are a stereo signal converter whereby it is possible to obtain low-redundancy encoding signals (M, S) even when the sound source locations are different, and a stereo signal reverse converter whereby it is possible to obtain higher-quality stereo signals. In a stereo signal converter (101), a correlation analyzer (111) calculates the power (PL) of a left channel signal (L), the power (PR) of a right channel signal (R), and a correlation value (CLR) using the left channel signal (L) and the right channel signal (R). A coefficient calculator (113) calculates a coefficient a by means of the correlation value (CLR) outputted from the correlation analyzer (111) based on the magnitude relationship between the power (PL) and the power (PR). A sum-difference calculator (115) adds the left channel signal (L) and the right channel signal (R) to generate a monaural signal (M). Also, the sum-difference calculator (115) generates a side signal (S) using the magnitude relationship between the power (PL) and the power (PR), and a coefficient obtained by encoding and decoding a.

摘要： A method of processing a signal is disclosed, which includes receiving a downmix signal, object information and rendering information; and generating downmix processing information using the object information and the rendering information, the object information including modified object level information, wherein the modified object level information is determined using a level of a modified object generated by applying a downmix gain to an object. Accordingly, in an apparatus for processing a signal and method thereof according to the present invention, the signal is decoded using object information including modified object level information. Therefore, since a downmix gain is not transmitted, the present invention is able to reduce a used bit for object information and decode a signal using less information.

摘要： The invention enables the inclusion of voice and remaining audio information at different parts of the audio production process. In particular, the invention embodies special techniques for VRA-capable digital mastering, accommodation of PCPV/PCA and/or SCRA signals in audio CODECs, VRA-capable encoders and decoders, and VRA in DVD and other digital audio file formats. The invention facilitates an end-listener's voice-to-remaining audio (VRA) adjustment upon the playback of digital audio media formats by focusing on new configurations of multiple parts of the entire digital audio system, thereby enabling a new technique intended to benefit audio end-users (end-listeners) who wish to control the ratio of the primary vocal/dialog content of an audio program relative to the remaining portion of the audio content in that program. The invention facilitates storage of VRA audio programs on optical storage media, authoring systems for VRA-capable DVDs, playback hardware integrated into VRA-capable optical disc apparatus, and VRA playback hardware for use with non-VRA capable optical disc playback apparatus.

摘要： A lossless encoder and decoder are provided for transmitting a multichannel signal on a medium such as DVD-Audio. The encoder accepts additionally a downmix specification and splits the encoded stream into two substreams, such that a two-channel decoder of meagre computational power can implement the downmix specification by decoding one substream, while a multichannel decoder can decode the original multichannel signal losslessly using both substreams. Further features provide for efficient implementation on 24-bit processors, for confirmation of lossless reproduction to the user, and for benign behaviour in the case of downmix specifications that result in overload. The principle is also extended to mixed-rate signals, where for example some input channels are sampled at 48 kHz and some are sampled at 96 kHz.

摘要： The present invention presents a way to augment the playback of a compact disk by increasing the resolution, the number of channel, or both during reproduction, while still allowing the resultant CD to be playable on a standard CD player. From a high quality original master or other source, it produces a set of conventional two track audio signals and a set of residual or additional audio data derived from the original master using this conventional stereo audio signal. Additionally, it extracts a set of control information relating this additional audio data to the conventional stereo signals. This additional audio data contains information from the original master that would otherwise be lost when encoded onto a conventional CD. Upon playback, the control information allows the additional audio data to be recombined with the conventional stereo signal in order to reconstruct the original master. A single CD embodiment places the conventional stereo tracks in the audio portion of a compact disk, with the residual or additional audio data and control information stored in the CD-ROM portion of the same disk. The described techniques extend to more general embodiments, since once the original signal is separated into a conventional stereo portion and the additional information, these may be delivered and stored independently in media other than a CD, with the conventional stereo portion usable by itself and only recombined with the additional information when augmented playback is desired.
摘要翻译：本发明提供了一种通过在再现期间增加分辨率，频道数量或两者来增加光盘的重放的方法，同时仍允许所得到的CD在标准CD播放器上播放。从高质量的原始主机或其他来源，它产生一组传统的双轨道音频信号，以及一组使用这种传统立体声音频信号从原始主机导出的残余或附加音频数据。此外，它提取了一组关于这个附加音频数据的控制信息与传统的立体声信号。这个额外的音频数据包含原始主机的信息，否则当被编码到常规CD上时将丢失。在重放时，控制信息允许附加的音频数据与传统的立体声信号重组，以便重建原始的主机。单个CD实施例将常规立体声轨道放置在光盘的音频部分中，其中存储在同一盘的CD-ROM部分中的残留或附加音频数据和控制信息。所描述的技术扩展到更一般的实施例，因为一旦将原始信号分离成传统的立体声部分和附加信息，这些信号可以独立地传送和存储在除了CD之外的媒体中，传统的立体声部分可以仅由本身使用当需要增强播放时与附加信息重新组合。

摘要： A method of embedding sound field control factors (SFC factors) into a sound source. The method includes coding sound field factors and sound field information to obtain sound field control factors for the sound source in a binary data type, and the sound field factors represent an acoustic characteristic of the sound source and the sound field information represents an environment under which the sound source is decoded, and watermarking the sound field control factors into the sound source without compressing the sound source. In this method, the SFC factors that represent characteristics of the sound source are embedded into the sound source itself using a digital watermarking technology. Therefore, the SFC factors need not be manually set by a user. In addition, the SFC factors can be reliably transmitted, irrespective of header corruption caused by format conversion and transmission of a compressed sound source.

摘要： A digital signal recording disc has a first area and a second area. The second area differs from the first area. The first area stores a first-channel digital audio signal and a second-channel digital audio signal. The first-channel digital audio signal results from quantizing a first-channel analog audio signal with a first quantization bit number. The second-channel digital audio signal results from quantizing a second-channel analog audio signal with a second quantization bit number. The second area stores information of the first and second quantization bit numbers.

摘要： An encoder for mixing a plurality of independent mono audio channels into a stereo recording and generating a restricted set of additional parameters used to master an audio track of a storage device is described. The plurality of independent mono audio channels are constructed such that the storage device can be played using an optical disk player so that in a first mode all of the plurality of independent mono audio channels are played as the stereo recording and in a second mode at least one of the plurality of independent mono audio channels can be unmixed and the stereo recording played with at least one mono audio channel removed. A corresponding decoder and an audio system comprising such encoder and decoder are also described.
