Digital Audio
This chapter is concerned with the application of modern signal processing techniques to the restoration of degraded audio signals. Although attention is focussed on gramophone recordings, lm sound tracks and tape recordings, many of the techniques discussed have applications in other areas where degraded audio signals occur, such as speech transmission , telephony and hearing aids. We aim to p...
متن کاملEl Pais Digital
Difícilmente otro signo monetario le quite protagonismo a la divisa estadounidense, sobre todo, cuando el euro y el Banco Central Europeo tienen poca trayectoria recorrida y Japón prefiere un perfil bajo para el yen, sostuvo el Dr. Arturo Porzecanski. En diálogo con ECONOMIA & MERCADO, este economista uruguayo radicado en Estados Unidos desde hace cuarenta años, que es consultado por las princi...
متن کاملAlgoritmo para el cálculo del ritmo en una señal de audio digital
In this paper presents an algorithm for extraction of audio rhythm of a digital signal. The rhythm is formed by changes of intensity in the audio data signal. The rhythm marks significant changes in the acoustic signals. Through a procedure of filtering for extraction the envelope of the audio signal, then through a square signal marked the start point and duration of changes on the envelope. T...
متن کاملAudio 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...
متن کاملPhysical audio digital filters
We propose an approach to insert physical objects in audio digital signal processing chains, filtering the sound with the acoustic impulse response of any solid measured in real-time. We model physical objects as a linear time-invariant system, which is used as an audio filter. By interacting with the object or with the measuring hardware we can dynamically modify the characteristics of the fil...
