Improved Lossless Transform Coding of Audio Signals
نویسندگان
چکیده
Recent papers have proposed linear prediction as a useful method for lossless audio coding. Transform coding, however, has hardly been investigated, although it seems to be more suited for the harmonic structure of most audio signals. In this paper we present some results on lossless transform coding of CD-quality audio data. One main aspect lies on a convenient quantization method to guarantee perfect reconstruction. We achieve bit rates which are lower than those obtained by lossless linear prediction schemes.

متن کاملLossless Audio Coding for MPEG - 4
Lossless audio compression has been an active research field for the past decade. The main application of the technology is in the archival of digital audio data. With today’s wide spread of broadband networks, the technology has also gradually become popular in online music sharing and distribution. Lossless audio compression can be categorized into two different technical approaches: predicti...
متن کاملImproved Integer Transforms for Lossless Audio Coding
Lifting scheme based integer transforms are very powerful tools to construct lossless coding schemes. These transforms such as the Integer Fast Fourier Transform (IntFFT) and the Integer Modified Discrete Cosine Transform (IntMDCT) are integer approximations of the original floatingpoint transforms, and hence there is an approximation error in the transform domain. This paper will propose struc...
متن کاملLossless Audio Compression Using Integer Modified Discrete Cosine Transform
Recently, an MPEG2 AAC [1] based lossless audio codec with the Integer MDCT (IntMDCT) was proposed [2]. The IntMDCT was constructed by lifting scheme [3] to hold the perfect reconstruction(PR). In this paper, we will evaluate the IntMDCT implemented by fixed-point arithmetic with quantized lifting coefficients in the MPEG2 AAC based lossless audio coding. The results indicate that there exists ...
متن کاملImproved Integer Transforms Using Multi-dimensional Lifting
Recently lifting-based integer transforms have received much attention, especially in the area of lossless audio and image coding. The usual approach is to apply the lifting scheme to each Givens rotation. Especially in the case of long transform sizes in audio coding applications, this leads to a considerable approximation error in the frequency domain. This paper presents a multidimensional l...
