Author Republic demands that all files be 44.1Khz. But when I save an Audacity file as 44.1Khz and upload it to Author Republic, it uploads as 48.0Khz. Why? and how can I save it as 44.1Khz?
Make sure your Project Rate is set to 44,100Hz.
Then after exporting and before uploading, check the file format with MediaInfoOnline.
