Questions and limitations
Are my recordings uploaded?
No. MediaInfo reads file chunks in your browser. The parser and its WebAssembly file load from Fiund, but your selected recordings and metadata are not sent to Fiund.
Does this verify dataset quality?
It checks readable metadata. It does not fully decode files, listen to recordings, identify duplicates, check permissions, or certify that a buyer will accept the data.
