What does the Audio Trimmer do?
The Audio Trimmer exports a shorter segment from one uploaded track. After you pick a file, the page tries to load duration in your browser using the HTML audio element’s metadata event; when that succeeds, the end field prefills to the full length and you can tighten it. Start and end accept flexible time strings: minutes and seconds like 1:05, plain seconds like 90, or hour-style 1:02:03 thanks to the shared parser. A live clip length line updates from your numbers, and Trim Audio stays disabled until end is greater than start and start is non-negative. Submitting uploads the file and sends numeric start and end (or a null end meaning use the detected file end on the server when you left the end field empty after metadata load). Progress shows uploading, queued, and processing until a download button appears.
Limits and tips
One file per run with a 100 megabyte dropzone cap. If duration shows as unknown—some codecs or containers block metadata in the browser—type an explicit end time so validation can pass. Very small clips are fine; ensure your end bound does not exceed the real length or the job may fail server-side.
Privacy
Audio is uploaded to Dynamic Duniya for processing and is subject to the same retention rules as other media jobs. Avoid confidential or rights-restricted material you should not store on a third-party service.
