Ecshop中插件icoolmedia的相关算法，不同的效果我们想要达到很简单需要找到一个平衡点，利用代码结构完成ifndef NS_H，从而达到一个有效利用率的提升。下面就上代码、 spx_ifft(inHandle-fft_table,inHandle-ft,szAudio); / overlap and add for(i = 0; i frame_size; i+) ioPcmi = inHandle-outbufi + szAudioi; for(i = 0; i frame_size; i+) inHandle-outbufi = szAudioinHandle-frame_size+i*inHandle-win_gain; / limit value of adapt_count if(inHandle-adapt_count 16000) inHandle-adapt_count = 2;文件 ns.h 455B / 本文来自于icoolmedia，相关算法请参考ifndef NS_H#define NS_H#include Platform.h#ifdef _cplusplusextern C #endiftypedef struct NoiseReduction_t NoiseReduction;NoiseReduction* NoiseReductionCreate(OsInt32 inSampleRate,OsInt32 inFrameSize);void NoiseReductionDestroy(NoiseReduction *inHandle);void NoiseReductionProcess(NoiseReduction *inHandle,OsInt16 *ioPcm);#ifdef _cplusplus#endif#endif文件 Platform.h 6KB /* * Copyright (c) 2013 刘志鹏.
