Abstract

La presente invención se refiere al método implementado por computadora descrito para suavizar las brechas de audio usando metadatos adaptativos que identifica un segmento de audio inicial y un segmento de audio subsecuente que sigue al segmento de audio inicial. El método accede a un primer conjunto de metadatos que corresponde a un último cuadro de audio del segmento de audio inicial y accede a un segundo conjunto de metadatos que corresponde al primer cuadro de audio del segmento de audio subsecuente. Los primero y segundo conjuntos de metadatos incluyen información de características de audio para los dos segmentos de audio. Luego, el método genera un nuevo conjunto de metadatos que se basa en ambos conjuntos de características de audio. El método además inserta un nuevo cuadro de audio entre el último cuadro de audio del segmento de audio inicial y el primer cuadro de audio del segmento de audio subsecuente y aplica el nuevo conjunto de metadatos al nuevo cuadro de audio. También se describen varios otros métodos, sistemas y medios legibles por computadora.
