The Journal of the Acoustical Society of America, 2009
An audio system for processing two channels of audio input to provide more than two output channels. The input may be conventional stereo material or compressed audio signal data. The audio processing includes separating the input signals into frequency bands and processing the frequency bands according to processes which may differ from band to band ...

Multimedia Security in Audio Signals
2022 IEEE International Conference on Current Development in Engineering and Technology (CCET), 2022The security of Digital media has been varying continuously due to advanced malware attacks. Multimedia security has become one of the major concerns since new technologies are introduced. The proposed paper applied the watermarking technique in digital audio signals in which unique data is inserted in one-dimensional data in such a way that it must ...

ZIPF ANALYSIS OF AUDIO SIGNALS
Fractals, 2004This paper deals with several of the possible uses of Zipf and inverse Zipf laws in the field of audio signal analysis. We show that these laws are powerful analysis tools allowing the extraction of information not available by standard methods. The adaptation of Zipf and inverse Zipf laws to audio signals requires a coding of these signals into text ...

The Journal of the Acoustical Society of America, 2007
An audio signal cable consisting of various combinations of two or more distinct types of conductors. The cable contains at least two conductors of different types. The individual conductors within the cable may be individually insulated or uninsulated. The individual conductors may also be of varying shapes and sizes.

The Lucasfilm Audio Signal Processor
Computer Music Journal, 1982The requirements of audio processing for motion pictures present several special problems that both make digital processing of audio very desirable and relatively difficult. The difficulties can be summarized as follows: (1) Large amounts of numerical computation are required, on the order of 2 million integer multiply-adds per second per channel of ...

As we have discussed in the earlier chapters, the phenomenon of sound can mean either an auditory sensation in the air or the disturbance in a medium that causes such a sensation. An interesting question is exactly how we go from such phenomena, to numbers inside a computer, stored in an array of integers, for example, that we can manipulate in ...
