Nero AAC Codec
__NOTOC__ Nero AAC Codec is a set of software tools for encoding and decoding Advanced Audio Coding (AAC) format audio, and editing MPEG-4 metadata. It was developed and distributed by Nero AG, and is available at no cost for Windows and Linux for non-commercial use. The codec was originally part of Nero Digital, but was later released as a stand-alone package. Nero's AAC encoder has been very competitive when tested against other encoders in scientific listening tests, for a time, second only to Apple's AAC encoder. In 2006, Chip Magazine (Germany) found that AAC files encoded with the Nero AAC encoder would consume as little as half of the space on a portable music player when compared to MP3 files of similar audio quality. Components and Capabilities The current package is labeled version "1.5.1.0", but contains the following three utilities: The encoder and decoder support MPEG-4 AAC LC, HE-AAC (AAC LC + SBR), and HE-AACv2 (LC + SBR + PS) Audio Object Types.

Parametric Stereo
Parametric Stereo (abbreviated as PS) is an audio compression algorithm used as an audio coding format for digital audio. It is considered an Audio Object Type of MPEG-4 Part 3 (MPEG-4 Audio) that serves to enhance the coding efficiency of low bandwidth stereo audio media. Parametric Stereo digitally codes a stereo audio signal by storing the audio as monaural alongside a small amount of extra information. This extra information (defined as "parametric overhead") describes how the monaural signal will behave across both stereo channels, which allows for the signal to exist in true stereo upon playback. History Background Advanced Audio Coding Low Complexity (AAC LC) combined with Spectral Band Replication (SBR) and Parametric Stereo (PS) was defined as HE-AAC v2. An HE-AAC v1 decoder will only give mono sound when decoding an HE-AAC v2 bitstream. Parametric Stereo performs sparse coding in the spatial domain, somewhat similar to what SBR does in the frequency domain. An AAC HE ...

Advanced Video Coding
Advanced Video Coding (AVC), also referred to as H.264 or MPEG-4 Part 10, is a video compression standard based on block-oriented, motion-compensated coding. It is by far the most commonly used format for the recording, compression, and distribution of video content, used by 91% of video industry developers . It supports resolutions up to and including 8K UHD. The intent of the H.264/AVC project was to create a standard capable of providing good video quality at substantially lower bit rates than previous standards (i.e., half or less the bit rate of MPEG-2, H.263, or MPEG-4 Part 2), without increasing the complexity of design so much that it would be impractical or excessively expensive to implement. This was achieved with features such as a reduced-complexity integer discrete cosine transform (integer DCT), variable block-size segmentation, and multi-picture inter-picture prediction. An additional goal was to provide enough flexibility to allow the standard to be applied ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Exact Audio Copy
Exact Audio Copy (EAC) is a CD ripping program for Microsoft Windows. The program has been developed by Andre Wiethoff since 1998. Wiethoff's motivation for creating the program was that other such software only performed jitter correction while scratched CDs often produce distortions. Overview Exact Audio Copy is proprietary freeware, free for non-commercial use. It is written for Microsoft Windows. It has also been tested to work under newer versions of Wine on Linux. EAC is used to convert the tracks on standard audio CDs to WAV files, which can then be transcoded into other formats. These include lossy ones such as MP3, AAC, Ogg Vorbis, or lossless ones such as ALAC, FLAC, or WavPack using external encoders. It also has the option of using the Windows Audio Compression Manager (ACM Codecs) for direct compression. It supports AccurateRip, which automatically compares the copy with rips made by others, and can automatically create cue sheets, with all gaps, track attribute ...

Shell Script
A shell script is a computer program designed to be run by a Unix shell, a command-line interpreter. The various dialects of shell scripts are considered to be scripting languages. Typical operations performed by shell scripts include file manipulation, program execution, and printing text. A script which sets up the environment, runs the program, and does any necessary cleanup or logging, is called a wrapper. The term is also used more generally to mean the automated mode of running an operating system shell; each operating system uses a particular name for these functions including batch files (MSDos-Win95 stream, OS/2), command procedures (VMS), and shell scripts (Windows NT stream and third-party derivatives like 4NT—article is at cmd.exe), and mainframe operating systems are associated with a number of terms. Shells commonly present in Unix and Unix-like systems include the Korn shell, the Bourne shell, and GNU Bash. While a Unix operating system may have a different d ...

Surround Sound
Surround sound is a technique for enriching the fidelity and depth of sound reproduction by using multiple audio channels from speakers that surround the listener ( surround channels). Its first application was in movie theaters. Prior to surround sound, theater sound systems commonly had three ''screen channels'' of sound that played from three loudspeakers (left, center, and right) located in front of the audience. Surround sound adds one or more channels from loudspeakers to the side or behind the listener that are able to create the sensation of sound coming from any horizontal direction (at ground level) around the listener. The technique enhances the perception of sound spatialization by exploiting sound localization: a listener's ability to identify the location or origin of a detected sound in direction and distance. This is achieved by using multiple discrete audio channels routed to an array of loudspeakers. Surround sound typically has a listener location ( sweet sp ...
