摘要
随着我国数字化、信息化进程的不断推进,各类图书馆、博物馆和档案馆都相继启动了对珍贵历史馆藏资料的数字化保存工作。音频资料因其材质的特殊性,需要通过现代科技手段对其进行后期处理,使其尽可能恢复历史原貌,更好的服务于今后的教学、科研工作。本文研究与探索了目前音频的噪音类型和各种降噪方法,在基于wxWidgets的音频修复工具Memo-ryAudio中综合应用这些方法,提供各类降噪专家模版,取得了较好的降噪效果。此系统还为今后降噪算法的不断扩展提供标准接口。
As China's digital, information-based process to continuously promote,many libraries and institutions have launched the project to preserve precious historical materials in digital. Based special nature of the audio materials, it's necessary to give modern technology through their post-processing, to resume their original appearance as much as possible. It's great valuable for teaching and research work in the future. The paper presents the research and explores on the domain of noise types and audio retrieval methods, and apply them to audio retrieval tool: MemoryAudio which developed basesed on wxWidgets.This tool provides several noise-reduce professional templates, and has achieved delightful result .The system provide the standard interface for audio-reduce arithmetic in the future.
