MP3 edited on Ableton and exported as Wav Fakin The Funk can't detect original bitrate

[David]

Hello there, I edited some MP3 320 on Ableton and then exported as Wav, I passed on Fakin The Funk and the software says its a Wav,

The Fukin The Funk can not detect the original 320 bitrate?

How can I be sure the Wav or the 320 that I got someone did not make the same thing?

Cheers

Converting to wav is losless,
So when the mp3 was really best quality (320), then the spectrum is fully-qualified and cannot be distinguished from a plain "real" wav.
