Ogg names the container
An Ogg file may contain Vorbis or Opus. Sound Flipper selects the qualified reader from the identification packet and then validates the stream. Other Ogg content, extra tracks or damaged page chains are not assumed to be ordinary audio.
Convert for a compatibility need
If a player accepts the original Ogg codec, another conversion may be unnecessary. MP3 is useful when the destination requires it, but both Vorbis and Opus sources have already undergone lossy encoding. A second lossy output can discard more information.
Presentation is checked before encoding
The reader resolves the actual decoded interval and retains float samples before MP3 encoding. Ogg Vorbis terminal granules are timeline positions, so the app does not simply treat their numeric value as a recording's sample count. Opus pre-skip, padding and required header gain have their own checks.
A practical comparison
For a downloaded Ogg lecture that a car player cannot open, confirm the destination really needs MP3, inspect the source and make one delivery copy. Listen to opening and closing speech and retain the Ogg original. See the Opus-specific guide and generation loss explained.

Can WAV restore quality lost in an MP3?
No. WAV can preserve the decoded signal without a new lossy encoding, but cannot recreate information already discarded.
Why was my file or output refused?
The actual codec, precision, layout or timing may fall outside the qualified subset. The app explains the restriction rather than silently reducing quality. See supported formats.
Does the maximum file size work on every device?
No. Limits are refusal ceilings. Browser quota and available memory may require smaller files. Physical mobile testing has not been performed for this preview.
