## Validated conversion workflow (v11.1)

The actual workspace opens from **Open audio conversion workspace**. Import one or more supported audio files and optionally listen to the first one before processing. Choose an output preset or manually select MP3/WAV, sample rate, mono/stereo, peak/silence processing, and finishing. During conversion, **Cancel after current track** stops the queue between tracks; a currently running browser render cannot be force-cancelled mid-file.

Completed WAV files are checked for RIFF/WAVE/data headers, declared audio bytes, and sensible nonempty output. Each successfully processed recording receives its own download button. Batch filenames are deduplicated so two sources with the same stem do not overwrite one another inside a ZIP. Individual failures appear in the status/error area and are not silently described as success.

MP3 uses the JavaScript LAME encoder; browsers must be able to retrieve that free library from an external CDN unless already loaded. If the encoder cannot load because of a network block or an offline visit, choose WAV. MP3 encoding has not been independently certified across all browsers. Long files need enough memory for offline rendering.
