There is provided an audio signal subband encoder which attains improved quality of sound by controlling allocation of the number of quantization bits to subband signals on the basis of an evaluation function combining the noise-to-mask ratio criterion with noise-to-signal ratio criterion in order to lessen the influence of the application error of the

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 ...

Popular television shows and movies involving law enforcement and forensic analysis sometimes include an example of a terribly scratchy and obliterated audio recording that is magically transformed into pristine sound, leading to the guilty culprit. Other plots might have a blurry handheld snapshot from which the technician pulls out a perfect image of

Audio Signal Synthesizer and Audio Signal Encoder
In accordance with a first aspect of the invention, an audio signal synthesizer generates a synthesis audio signal having a first frequency band and a second synthesized frequency band derived from the first frequency band. The audio signal synthesizer comprises a patch generator, a spectral converter, a raw signal processor and a combiner.openaire
An audio decoder for providing a decoded audio information on the basis of an entropy encoded audio information comprises a context-based entropy decoder configured to decode the entropy-encoded audio information in dependence on a context, which context is based on a previously-decoded audio information in a non-reset state-of-operation.

Audio Texture Analysis of Biomedical Audio Signals
<p>The concept of textures is not new to humans. In general, a texture is the physical feel of something when touched, viewed, or heard. For images, the texture could be categorized into smooth or rough, coarse or fine, matt or glossy, and other. But for audio signals, the definition of audio textures is imprecise and textures are often explainedopenaire +1 more source
