可用作各类音频降噪算法测试 32KHz wav格式

含有 NoiseX-92噪声库-完整版（wav格式）： https://download.csdn.net/download/u012933021/10836240 以及（mat格式）： http://spib.linse.ufsc.br/noise.html 100种环境噪声库： http://www.pudn.com/Download/item/id/3457634.html These nonspeech, environmental sounds can be used as nonspeech noises for evaluating speech segregation systems, among others. They are available in waveform, and can be downloaded in one ZIP file. The contents are: N1-N17: Crowd noise N18-N29: Machine noise N30-N43: Alarm and siren N44-N46: Traffic and car noise N47-N55: Animal sound N56-N69: Water sound N70-N78: Wind N79-N82: Bell N83-N85: Cough N86: Clap N87: Snore N88: Click N88-N90: Laugh N91-N92: Yawn N93: Cry N94: Shower N95: Tooth brushing N96-N97: Footsteps N98: Door moving N99-N100: Phone dialing

WAV噪声库里面有8个WAV文件(8Khz采样，8bit量化)，包括高斯白噪声、粉红噪声，汽车噪声，战斗机噪声，工厂噪声等，由noisex-92噪声库.mat文件转化而成，对于研究语音增强和音频降噪需要稳定噪声源的人来说非常有帮助。
