It not only can be modified and patch sounds, you can also simulate the real environment effects. Reverb can increase the beauty of the sound, which is widely used. This paper introduces the principle and reverb technical indicators, and the development direction of reverb. And the establishment of a reverberation model and the audio signal using MATLAB reverb processing. Also describes the format of the audio signal is an audio signal associated with the MATLAB format. Write delay reverb program, and take advantage of these programs and listen to the song reverb effect. Keywords Signal Processing, MATLAB, delay, Reverberation 攀枝花學(xué)院本科畢業(yè)設(shè)計(論文) 目 錄 目 錄 摘 要 I ABSTRACT II 1 緒 論 1 課題背景 1 混響器簡介 1 數(shù)字混響器的工作原理 1 混響器的發(fā)展現(xiàn)狀 1 語音信號處理 2 信號的定義 2 語音信號處理的發(fā)展 3 MATLAB 在數(shù)字語音信號處理中的應(yīng)用 3 設(shè)計理念 4 2 混響的原理 6 全通濾波混響模型 6 6 18
