2000-8-25 · For very low bit rate audio coding applications in mobile communications or on the Internet, parametric audio coding has evolved as a technique complementing the more traditional approaches. These are transform codecs originally designed for achieving CD-like quality on one hand, and specialized speech codecs on the other. Both of these techniques usually represent …

2005-1-1 · Parametric-stereo coding is a technique to efficiently code a stereo audio signal as a monaural signal plus a small amount of parametric overhead to describe the stereo image. The stereo properties are analyzed, encoded, and reinstated in a decoder according to spatial psychoacoustical principles. The monaural signal can be encoded using any ...

2022-1-6 · parametric audio coding requirements. Third, as explained in [16], the time-envelopes resulting for the synthesis with an EDS model are not smooth, and smoothness is desirable in the context of audio coding in order to avoid discontinuities at time-segment boundaries. In this paper, we propose an efficient

2013-3-28 · Parametric Audio Coding With Exponentially Damped Sinusoids. Abstract: Sinusoidal modeling is one of the most popular techniques for low bitrate audio coding. Usually, the sinusoidal parameters (amplitude, pulsation and phase of each sinusoidal component) are kept constant within a time segment. An alternative model, the so-called Exponentially ...

2016-9-5 · Parametric Stereo increases the coding efficiency a second time by exploiting a parametric representation of the stereo image of a given input signal. Thus, HE-AAC v2 is a superset rather than a substitute for the AAC core codec and extends the reach of high-quality MPEG-4 audio to much lower bitrates. Given this superset
