About Audio Trimmer
Last updated: May 2026
OptiPix Audio Trimmer 允许您直接在浏览器中剪切和修剪音频文件。上传 MP3、WAV、OGG、FLAC、AAC、M4A 或 WebM 文件，即可看到可视化的波形显示。拖动波形上的选择句柄，精确选择要保留或删除的部分。添加淡入淡出效果以实现平滑过渡。支持多种格式导出，包括 MP3、WAV、OGG、FLAC 和 AAC，并可调整比特率。波形编辑器支持缩放、精确时间输入和键盘快捷键，以实现帧级精确编辑。使用 FFmpeg.wasm 进行高质量编码 - 所有操作都在您的浏览器本地进行。您的音频文件绝不会上传到任何服务器。
How It Works
该工具使用 Web Audio API 解码您的音频文件以生成可视化的波形。您可以使用可拖动的句柄或精确的时间输入来选择片段。然后，FFmpeg.wasm 会使用您选择的格式、比特率和淡化效果对选定的片段进行编码 - 所有这些都在您的浏览器本地运行。
Use Cases
- •剪切歌曲片段作为铃声
- •修剪播客的开头和结尾
- •提取 TikTok 或 Instagram 的片段
- •从语音录音中移除静音
- •为音乐制作创建音频样本
