什么软件可以清除录音里的噪音

使用GoldWave可以去除音频噪音，步骤如下：
1、打开一个goldwave软件：

2、使用GoldWave软件打开一个音频文件：

3、使用鼠标在软件中选取噪音部分，注意尽量切割的清楚，避免影响到主音频：

4、选中噪音后，点击上面工具栏的降噪按钮：
/iknow-pic.cdn.bcebos.com/83025aafa40f4bfb81f1c1f00d4f78f0f7361874"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/83025aafa40f4bfb81f1c1f00d4f78f0f7361874?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/83025aafa40f4bfb81f1c1f00d4f78f0f7361874"/>
5、点击后出现降噪的选项框：
/iknow-pic.cdn.bcebos.com/c75c10385343fbf2591af987be7eca8065388f64"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/c75c10385343fbf2591af987be7eca8065388f64?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/c75c10385343fbf2591af987be7eca8065388f64"/>
6、在降噪选项框内选择使用剪贴板，点击确定：

7、按照上述步骤处理后，可以看到音频中的噪音部分不见了，已经处理完毕。

用CoolEdit Pro或他的升级版AdobeAudition可以很方便地把录音里的噪声消除（CoolEdit Pro和AdobeAudition可以在百度搜索到）。方法（以CoolEdit Pro为例）：
1：打开需要处理的音频文件；
2：按：水平放大按钮，放大波形，找出有代表性的噪音波形并鼠标左键拖动选中它；
3：点：效果/噪音消除/降噪器；
4：点：噪音采样按钮，再点：预览按钮试听，如不满意，再修改参数，如满意，可关闭降噪窗口（因为是对当前文件降噪，不需要保存）；
5：回到编辑窗口，选中全部波形，点：效果/噪音消除/降噪器，再点确定按钮，软件就开始降噪了；
6：等处理完毕起名保存文件。
