This is just my own suggestion, but I would personally render and work with a .WAV format when it comes to working within a DAW. There are "pros" and "cons" to using both. WMA is a Microsoft exclusive format, and it's not supported across the board by all media players and operating systems (considering it's Microsoft only). If you are working in a Windows environment, there isn't any harm in working with WMA files at all, and it will help you save space as .WAV files are indeed quite large. WAV files are an uncompressed format, which means they are exact copies of the original source audio. Since they're uncompressed, they do take up extra space that a compressed format wouldn't.

We hope this helps!
