Ecshop中插件icoolmedia的相关算法.docx

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 inHandle-frame_size; i++) ioPcm[i] = inHandle-outbuf[i] + szAudio[i]; for(i = 0; i inHandle-frame_size; i++) inHandle-outbuf[i] = szAudio[inHandle-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.
