When you upload audio assets, it should follow the following standards

• Audio file(s) must to be wav-file, sample rate at 44,1 kHz, stereo and 16bit. The file name must end with .wav
• We don’t distribute standalone short tracks that aren’t part of a full release product. Songs less than 30 seconds don’t receive payouts from the stores.
• The average track length on an album cannot be less than one minute.

We are working on allowing high-res audio upload via our platform. If you want to add high-res audio, please contact us.
