针对声回波对消、语音去混响及语音盲信号分离等声学信号处理应用领域中 ,自适应算法的有效性、实时可行性的研究与测试 ,作者研究并构建出基于浮点DSP及虚拟仪器LabVIEW的实时声学信号处理实验平台 (EP) .该EP既能同时测量多路房间冲激响应 (RIR)及两两RIR间的差异(DRIR)信息 ,并用于相关算法的离线研究 ,又能借助DSP可编程的灵活性及LabVIEW方便的图形用户界面对相关的自适应算法进行实时实验研究 For the acoustic echo cancellation, speech dereverberation and speech blind signal separation and other acoustic signal processing applications, the effectiveness of adaptive algorithms, real-time feasibility studies and tests, the authors study and build based on floating-point DSP and virtual Instrument LabVIEW real-time acoustic signal processing experiment platform (EP). The EP can simultaneously measure multiple rooms impulse response (RIR) and any difference between two RIR (DRIR) information, and used for offline research related algorithms, but also Real-time experimental research on adaptive algorithms with DSP programmable flexibility and LabVIEW’s easy-to-use graphical user interface
