Local editing and processing
Tools decode files in the browser to cut, merge, fade, adjust amplitude, or work with channels. Downloadable edits export as PCM WAV rather than pretending the browser provides unavailable output codecs.
Analysis, recording, and compatibility
View amplitude, detect low-level intervals, and inspect decoded properties. The recorder requests permission only when recording starts and keeps the actual format supported by MediaRecorder.
Frequently asked questions
Are audio files uploaded to Utilsha?
No. These tools process audio locally in the browser.
Can I load and download MP3?
The browser may decode MP3 when that codec is available, but edits download as PCM WAV. The extension is never changed by itself.
