MP3 is a common choice for sound-only playback. Keep your WMA originals while you check the converted files.
Three Steps to Your Output
Add the WMA Files
Select Add Media and choose your local WMA sources. Check the queue so that you export the files you intend to keep.
Set MP3 Output
Choose MP3 from the Audio category and review the bitrate and sample-rate settings. Avoid choosing a quality level higher than you need.
Convert to a Separate Folder
Choose Save to, then Convert. Play the new MP3 files and check their duration, audio and metadata.

Protected Sources
Rights-protected or damaged files may not be readable. This workflow does not remove DRM or bypass access controls. Use a readable source you are authorized to convert.
