Control Techniques of Television Audio Signal

Audio Signal Classification: History and Current Techniques

Audio signal classification (ASC) consists of extracting relevant features from a sound, and of using these features to identify into which of a set of classes the sound is most likely to fit. The feature extraction and grouping algorithms used can be quite diverse depending on the classification domain of the application. This paper presents background necessary to understand the general resea...

Beamforming Techniques for Multichannel audio Signal Separation

Beamforming is a signal processing technique. It has been studied in many areas such as radar, sonar, seismology and wireless communications, to name but a few. It can be used for a myriad of purposes, such as detecting the presence of a signal, estimating the direction of arrival, and enhancing a desired signal from its measurements corrupted by noise, competing sources and reverberation. Actu...

Audio for Digital Television

Audio is an area in television broadcasting and production that causes apprehension with some engineers because of its complexity and the care needed to get it right in design, installation, and operations. With the transition to digital television (DTV), there is a new level of uncertainty because the requirements for audio are far more advanced and complex than before. Yet digital audio provi...

MUS 424 : Signal Processing Techniques for Digital Audio Effects

There are typically four steps in producing a CD or movie soundtrack, as shown in Figure . In tracking sounds are recorded or synthesized and arranged in tracks. The tracks are then processed in the mixing stage to form a stereo or multichannel mix. The idea is to arrange the sounds spatially and spectrally, to manipulate their character for artistic purposes, and also to fix problems in the tr...
