Trim supported audio files and export the selected segment as WAV. This workspace gives you an immediate, inspectable result without creating an account. Inputs are not uploaded by the tool, and original files on your device are not overwritten.
The browser must support the input codec. Audio editing exports uncompressed 16-bit WAV, which can be larger than the original. Peak normalization is not LUFS mastering.
No desktop application is required. Open this page in a current browser with JavaScript enabled. PDF, OCR and Markdown features load an additional engine on demand; an internet connection may be needed the first time.
The application does not upload or store your file contents. Results stay in this browser until you download or copy them. The server still receives normal page requests; see our privacy page for the distinction.
Check your input, units and options, then try a smaller example. Keep the original file and review important results manually. Browser format support and memory limits can affect file tools.
