WAV compared with MP3
WAV can store uncompressed audio. MP3 is much smaller, but the conversion is lossy and cannot improve a low-quality source.
What FLUX actually changes
The media engine decodes the WAV stream to PCM, then encodes a new MP3 with libmp3lame at the bitrate you choose.
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.

Before you start
Audio conversion runs in your browser and depends on the codecs available to the bundled media engine. Very large files need enough free device memory.
