Does the conversion of APE to FLAC with dBpoweramp retain the identical sound quality of the original APE files? If so, I'll convert all my APE files to FLAC. By the way, can this software convert many files simultaneously or only convert a single file each time?
Yep, absolutely, APE to FLAC: lossless to lossless. My version of dBpoweramp only converts single file or two at the time, so it does take some time, but to me at least, the quality of conversion etc. is more important than speed. So I usually let it convert overnight.
If you set it up correctly, dBpoweramp should be able to read the tags and convert to whatever format you prefer, and it should function without any extreme delay etc. on the Studio/Rocoo. This works for me, but could different for others.
