I have some typical digital mode audio files available in the 'digital mp3.zip' ZIP attachment, MP3 files within, mono only on the left channel, based on my callsign. Not all modes are there but maybe some of the more common ones. These were created by WSJT-X 2.6.1 and the audio output recorded on a second PC using Audacity software. Any missing ones could be added to expand the library. I have the same files in WAV format but that ZIP is 10 times the size of the MP3 version.
The filenames follow this format : ft8 1800 #14 mono 14june23.mp3
FT8 mode, 1800 Hz, about 14 seconds long, mono (Left), creation date.
If you are trying to decode these via software, remember that you will probably need to sync the start to the 00 secs mark on the PC clock - typical accuracy required is within 2 seconds. Random play times will NOT work. You may need to convert to another audio format (eg WAV) depending on the software package's needs - Audacity is good for this task.
