In order to transfer your recordings to a CD, first you need to transfer them to a PC and then to a CD using a burning software. To transfer your files from iPad to a computer you can use iExplorer. This software will allow you to manage and transfer all files from your iPad. To create a CD with these files, I suggest you visit Software Informer's webiste in order to find a burning software.
