pcmnoisesupression's Introduction

利用 WebRTC 音频处理模块对 PCM语音数据(AudioRecord 录制出的裸数据) 进行降噪处理,然后播放测试降噪效果(AudioTrack 播放PCM语音数据)

编译说明

如果需要自己编译jni代码打包so库,需要配置NDK环境。

降噪方法

/**
 * 音频降噪
 * @param file_in 输入文件
 * @param file_out 输出文件
 * @param sample 采样率
 * @param mode 降噪强度0-2
 */
public static native void noiseSuppression(String file_in,String file_out,int sample,int mode);

/**
 * 音频降噪
 * @param buffer 音频文件流
 * @param sample 采样率
 * @param mode   降噪强度0-2
 */
public static native void noiseSuppressionByBytes(byte[] buffer,int sample,int mode);
