Abstract

Los recursos informáticos que se necesitan para aplicar un banco de filtros basado en transformada a señales de audio de ancho de banda limitado se reducen al realizar un proceso integrado de combinar datos de entrada de valores reales con datos de valores complejos y aplicar una transformada corta a los datos de valores complejos, aplicando un banco de transformadas muy cortas a la salida del proceso de integración, y derivando una secuencia de datos de salida de valores reales de las salidas del banco de transformadas muy cortas.The computing resources needed to apply a filter bank based on transform to audio signals of limited bandwidth are reduced by performing an integrated process of combining real value input data with complex value data and applying a short transform to complex value data, applying a very short transform bank at the exit of the integration process, and deriving a sequence of real value output data from the outputs of the very short transform bank.
