About this tool
Trim audio online without uploading your file
AudioDock lets you trim the beginning, end or any unwanted portion of an audio recording directly in your browser. Choose the section you want to keep, preview the result and export the edited file without sending the original audio to a remote processing server.
Audio trimming is useful for shortening voice recordings, removing unwanted introductions or endings, preparing podcast clips, creating samples and cleaning interviews.
Unlike many cloud-based audio cutters, AudioDock processes the recording locally. Your file remains on your computer, phone or tablet during the operation.
