Ecshop中插件icoolmedia的相關(guān)算法

1、Ecshop中插件icoolmedia的相關(guān)算法，不同的效果我們想要達(dá)到很簡(jiǎn)單需要找到一個(gè)平衡點(diǎn)，利用代碼結(jié)構(gòu)完成ifndef NS_H，從而達(dá)到一個(gè)有效利用率的提升。下面就上代碼、 spx_ifft(inHandle->fft_table,inHandle->ft,szAudio); / overlap and add for(i = 0; i < inHandle->frame_size; i+) ioPcmi = inHandle->outbufi + szAudioi; for(i = 0; i < inHandle->frame_size;

2、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 / 本文來(lái)自于icoolmedia，相關(guān)算法請(qǐng)參考ifndef NS_H#define NS_H#include "Platform.h"#ifdef _cplusplusextern &qu
