Here is the FT8 WAV test file.
On an AMD64 machine:
1 second using the fast decode settings.
We were able to get the MSHV's FT8 engine to work on Android, thanks to the work done by https://github.com/sannysanoff/SDRPlusPlusBrown folks.
Around ~4.5 seconds to decode the same file.
This is why we can't really have full-blown realtime FT8 decoder(s) on Android just yet!
Idea: But we can surely use this full-blown FT8 decoder in our FT8 Decoder app which has no realtime requirements!
…
Side-note: The best FT8 decoding performance is given by WSJT-X_IMPROVED as of September-2025.
