Ac3 Filter Codec For Dolby Digital Plus' title='Ac3 Filter Codec For Dolby Digital Plus' />Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at the same bit rate. The confusingly named AAC HE AAC does so only at low bit rates and less so at high ones. AAC has been standardized by ISO and IEC, as part of the MPEG 2 and MPEG 4 specifications. Part of AAC, HE AAC AAC, is part of MPEG 4 Audio and also adopted into digital radio standards DAB and Digital Radio Mondiale, as well as mobile television standards DVB H and ATSC MH. AAC supports inclusion of 4. Hz audio channels in one stream plus 1. LFE, limited to 1. Ac3 Filter Codec For Dolby Digital Plus AudioHz channels, up to 1. The quality for stereo is satisfactory to modest requirements at 9. VBR. Tests of MPEG 4 audio have shown that AAC meets the requirements referred to as transparent for the ITU at 1.

AAC is also supported by manufacturers of in dash car audio systems. HistoryeditAAC was developed with the cooperation and contributions of companies including AT T Bell Laboratories, Fraunhofer IIS, Dolby Laboratories, Sony Corporation and Nokia. It was officially declared an international standard by the Moving Picture Experts Group in April 1. It is specified both as Part 7 of the MPEG 2 standard, and Subpart 4 in Part 3 of the MPEG 4 standard. StandardizationeditIn 1. AAC was first introduced as MPEG 2 Part 7, formally known as ISOIEC 1. This part of MPEG 2 was a new part, since MPEG 2 already included MPEG 2 Part 3, formally known as ISOIEC 1. MPEG 2 BC Backwards Compatible. Therefore, MPEG 2 Part 7 is also known as MPEG 2 NBC Non Backward Compatible, because it is not compatible with the MPEG 1 audio formats MP1, MP2 and MP3. MPEG 2 Part 7 defined three profiles Low Complexity profile AAC LC LC AAC, Main profile AAC Main and Scalable Sampling Rate profile AAC SSR. AAC LC profile consists of a base format very much like AT Ts Perceptual Audio Coding PAC coding format,1. TNS,1. 4 the Dolby Kaiser Window described below, a nonuniform quantizer, and a reworking of the bitstream format to handle up to 1. LFE channels and 1. The Main profile adds a set of recursive predictors that are calculated on each tap of the filterbank. The SSR uses a 4 band PQMF filterbank, with four shorter filterbanks following, in order to allow for scalable sampling rates. In 1. 99. 9, MPEG 2 Part 7 was updated and included in the MPEG 4 family of standards and became known as MPEG 4 Part 3, MPEG 4 Audio or ISOIEC 1. This update included several improvements. One of these improvements was the addition of Audio Object Types which are used to allow interoperability with a diverse range of other audio formats such as Twin. VQ, CELP, HVXC, Text To Speech Interface and MPEG 4 Structured Audio. Another notable addition in this version of the AAC standard is Perceptual Noise Substitution PNS. In that regard, the AAC profiles AAC LC, AAC Main and AAC SSR profiles are combined with perceptual noise substitution and are defined in the MPEG 4 audio standard as Audio Object Types. X/1/199dbc31a922420e90908991662dec524cafb5ba.jpg' alt='Ac3 Filter Codec For Dolby Digital Plus' title='Ac3 Filter Codec For Dolby Digital Plus' />MPEG 4 Audio Object Types are combined in four MPEG 4 Audio profiles Main which includes most of the MPEG 4 Audio Object Types, Scalable AAC LC, AAC LTP, CELP, HVXC, Twin. VQ, Wavetable Synthesis, TTSI, Speech CELP, HVXC, TTSI and Low Rate Synthesis Wavetable Synthesis, TTSI. The reference software for MPEG 4 Part 3 is specified in MPEG 4 Part 5 and the conformance bit streams are specified in MPEG 4 Part 4. MPEG 4 Audio remains backward compatible with MPEG 2 Part 7. The MPEG 4 Audio Version 2 ISOIEC 1. Amd 1 2. 00. 0 defined new audio object types the low delay AAC AAC LD object type, bit sliced arithmetic coding BSAC object type, parametric audio coding using harmonic and individual line plus noise and error resilient ER versions of object types. It also defined four new audio profiles High Quality Audio Profile, Low Delay Audio Profile, Natural Audio Profile and Mobile Audio Internetworking Profile. The HE AAC Profile AAC LC with SBR and AAC Profile AAC LC were first standardized in ISOIEC 1. Amd 1 2. 00. 3. 2. The HE AAC v. 2 Profile AAC LC with SBR and Parametric Stereo was first specified in ISOIEC 1. Amd 2 2. 00. 6. 2. The Parametric Stereo audio object type used in HE AAC v.

The current version of the AAC standard is defined in ISOIEC 1. AAC v. 2 is also standardized by ETSI European Telecommunications Standards Institute as TS 1. Toko Airsoftgun Tangerang more. The MPEG 4 Part 3 standard also contains other ways of compressing sound. These include lossless compression formats, synthetic audio and low bit rate compression formats generally used for speech. AACs improvements over MP3editAdvanced Audio Coding is designed to be the successor of the MPEG 1 Audio Layer 3, known as MP3 format, which was specified by ISOIEC in 1. MPEG 1 Audio and 1. MPEG 2 Audio. Blind tests in the late 1. AAC demonstrated greater sound quality and transparency than MP3 for files coded at the same bit rate,2 but since that time numerous codec listening tests have shown that the best encoders in each format are often of similar quality statistically tiedcitation needed and that the quality is often dependent on the encoder used even within the same format. As an approximation, when using the best encoders, AACs advantage over MP3 tends to be evident below around 1. AAC encoders are not as good as the best MP3 encoder as they do not take optimal advantage of the additional encoding tools that AAC makes available. Improvements include More sample frequencies from 8 to 9. Hz than MP3 1. 6 to 4. HzUp to 4. 8 channels MP3 supports up to two channels in MPEG 1 mode and up to 5. MPEG 2 modeArbitrary bit rates and variable frame length. Standardized constant bit rate with bit reservoir. Higher efficiency and simpler filter bank rather than MP3s hybrid coding, AAC uses a pure MDCTHigher coding efficiency for stationary signals AAC uses a blocksize of 1. MP3s 5. 76 sample blocksHigher coding accuracy for transient signals AAC uses a blocksize of 1. MP3s 1. 92 sample blocksCan use Kaiser Bessel derived window function to eliminate spectral leakage at the expense of widening the main lobe. Much better handling of audio frequencies above 1.
