Description

The first time you use this tool, you need to wait for FFmpeg.wasm to download and load.

This tool is built on FFmpeg.wasm, porting the industry-standard FFmpeg multimedia processing engine to the browser via WebAssembly technology. All audio processing operations are completed on your local device without uploading to any server, ensuring the privacy and security of your audio files.

The format for start and end times is: HH:mm:ss.SSS (hours:minutes:seconds.milliseconds), for example: 00:05:30.123, which means 5 minutes 30 seconds 123 milliseconds.
