Studi dan Analisis Kinerja Mpeg Surround pada Bitrate 256 – 400 Kbps
Jurnal Nasional Teknik Elektro, 2016 MPEG Surround is one of the spatial audio codings that popularly used. MPEG Surround is generally used at a low bitrate such as 64, 96 and 160 kbps. MPEG Surround can be used at high bitrates, but the audio quality produced in the bitrate is not yet ...

Audio codec identification from coded and transcoded audios
Digital Signal Processing, 2013 A novel technique is presented to identify the codec of a coded audio. The technique does not perform decoding, utilize any coding metadata, or assume information about the structure describing the bit stream format of a codec. The underlying idea of the technique is that the design choices governing the compression level, audio quality and complexity ...

A Psychoacoustic-Based Multiple Audio Object Coding Approach via Intra-Object Sparsity
Applied Sciences, 2017 Rendering spatial sound scenes via audio objects has become popular in recent years, since it can provide more flexibility for different auditory scenarios, such as 3D movies, spatial audio communication and virtual classrooms. To facilitate high-quality

Digital Signal Processing, 2020 Abstract In this paper an audio coding scheme based on the empirical mode decomposition in association with a psychoacoustic model is presented. The principle of the method consists in breaking down adaptively the audio signal into intrinsic oscillatory components, called Intrinsic Mode Functions (IMFs), that are fully described by their local ...
