Converting MP3 to WAV does not restore details lost during MP3 encoding. It changes compatibility and editing behavior, not source quality.
What FLUX actually changes
The MP3 is decoded to 16-bit PCM and written into a WAV container. No lossy encoder or bitrate control is used for the output.
Your file stays with your browser
FLUX does not send selected files to its own conversion server. Processing is handled locally on your device, while versioned conversion modules may be loaded securely when needed.
