Joint Encryption and Compression of Audio Based on Compressive Sensing
2019 42nd International Conference on Telecommunications and Signal Processing (TSP), 2019The increasing amount of sensible information transmitted through insecure communications channels requires, the development of algorithms with the capacity of simultaneously compress and encrypt digital information. To solve this problem, this paper proposes an algorithm based on compressing sensing, which simultaneously compress and encrypt audio ...

A Study on the Best Wavelet for Audio Compression
2006 Fortieth Asilomar Conference on Signals, Systems and Computers, 2006This paper proposes a new low cost algorithm for searching the minimum bit rate wavelet-packet representation to encode high quality general audio in a perceptual sense. Our study proposes the use of a particular family of wavelets, and the adaptive choice of the corresponding filters' length, according to the proposed cost function and the input audio

A learning system for audio compression
Proceedings of the 14th International Conference on Information Integration and Web-based Applications & Services, 2012One of the most common methods of audio compression is MP3. In this paper, we describe a multimedia learning system for helping learners to study the MP3 audio compression technique. Our system is designed for engineering learners with active preferences.

In this chapter, we consider the set of tools for audio compression applicable to general audio, such as music, as opposed to specifically speech compression developed under the aegis of the Motion Picture Experts Group, MPEG. Surprisingly, this subject has much to do with psychology, specifically within the field of aural sense perception ...

Standards for Audio Compression
1995Digital audio is an integral part of any video or multimedia application and may consume a considerable portion of the overall bandwidth. Therefore, efficient compression of the audio data is as important as the efficient compression of the video data.

Scalable Audio Compression at Low Bitrates
IEEE Transactions on Audio, Speech, and Language Processing, 2008A perceptually scalable audio coder generates a bit-stream that contains layers of audio fidelity and is encoded in such a way that adding one of these layers enhances the reconstructed audio by an amount that is just noticeable by the listener. Such algorithms have applications like music on demand at variable levels of fidelity, for instance using 3G

Detecting double compression of audio signal
SPIE Proceedings, 2010MP3 is the most popular audio format nowadays in our daily life, for example music downloaded from the Internet and file saved in the digital recorder are often in MP3 format. However, low bitrate MP3s are often transcoded to high bitrate since high bitrate ones are of high commercial value.

Parameter Analysis for GLZ Audio Compression
Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2006The generalized Lempel-Ziv (GLZ) paradigm for lossy compression for audio relies upon the fact that music, in particular electronically generated sound, has a substantial level of repetitiveness within a single clip. Thus, GLZ compresses each of the overlapped and transformed windows of the audio using a linear combination of filtered past windows ...

Lossless compression of binary audio signals
Proceedings DCC '98 Data Compression Conference (Cat. No.98TB100225), 2002A binary data format, known as direct stream digital (DSD), has been proposed for the representation of audio signals. The typical sample rate of these binary audio signals is 64 x 44.1 kHz, so the bit rate equals 64 x 44100 = 2.8 Mbit/s (per audio channel).
