This is the Polywav format. Import the POD00001.WAV file in Audacity and you should get all 14 tracks. Then you need to combine the stereo tracks (Left and Right tracks) Main mix is in track 1 (Left) and 2 (Right) Then you continue with the same method for the other Podcasts recordings (POD00002.WAV, POD00003.WAV, etc...) https://rode.com/en/user-guides/rodecaster-pro/recording-to-a-computer-via-usb
